Industry water pumping and drinking water

The emerging uses of renewable energy are for agriculture, small industry, water pumping and cottage applications (sawmills and mechanical power). Furthermore, social services, such as education and health care can be supported by renewable energy. Water pumps driven by wind have historically played a role in rural areas. More recently, interest is growing in solar PV-powered water pumps, along with biogas for water pumping in engines run on diesel and biogas. Standalone energy systems can power small industries, thereby creating local jobs and opportunities. In fact, the development of mini-grids and industry goes hand in hand. As small businesses grow, the economic viability of mini-grids increases. With the availability of energy, new possibilities open up. Renewable energy can also power mechanical pumping and filtering (as well as ultraviolet disinfection) to provide clean drinking water. This is emerging as a potential major market in developing countries.

Using water resources for your power needs

1 Waterways can dry up in droughts. 1 Upfront costs are high, particularly for stationary water systems. In addition to the hydro generator, you need a good inverter to convert the raw voltages from the alternator into the standard household voltages that will run your equipment. Not many hydro generators are sold because so few people have access to a good water supply.

Heating and Purifying Water

Purifying Your Drinking Water

Here's a great bite-sized solar project for the do-it-yourselfer. Not only can you build a solar water-purification system such as the one in Figure 10-5, but you can also design it. Designing is just as much fun as building, and it's more rewarding because the system's entirely yours (unless it doesn't work, of course then you need to figure out how to blame somebody else). The system uses distillation, a process that can remove salts, microorganisms, and even chemicals such as arsenic, leaving you with pure H2O. Here's how it works If you leave salty or contaminated water in an open container, the water evaporates and leave the contaminants behind. If you heat the water, the process speeds up considerably.

Water Wells

What do you do when the creek stops running and the springs go dry Drill for water Drilling a water well is a cross between praying in church and high stakes poker in Las Vegas. Drilling is a high stress, big risk undertaking. Here's how to avoid some of the potential mistakes. Once the well comes in, then the water must be pumped from the well. Basic physics determines the rules of water transfer from well to usage point. In this area, we stand a fighting chance of seeing our work and money realized. Every well, water system, location, and water need is different. I am interested here in not making expensive mistakes during the potentially disastrous drilling phase. Find and use all the data that you can collect about water wells in your area. Any close neighbor with a water well can provide valuable information. Wells are registered in most counties. These records are public. The big questions are how deep and how much water. Some folks use a dowser to locate water. I have no hard...

Solar Water Systems

No space for a traditional two-tank solar hot water system No problem. Single-tank solar water heating systems offer great performance and high efficiency, all in one small footprint. A single-tank solar water heating system combines solar preheated water and backup heating into one tank, in contrast to a typical two-tank system, which separates these functions. Both singletank and two-tank solar hot water heating systems can save 55 to 85 on water heating costs, depending on your local climate. Considering that water heating is the second-largest energy guzzler in most homes, this translates into serious savings over the long haul, since solar hot water systems have an expected life between 15 and 30 years. But does one system have an advantage over the other When space is at a premium, a single-tank solar hot water system (left) offers high performance in a smaller footprint than a typical two-tank setup (right). tank. The element heats the water in the upper half of the tank, while...

Wind and Water Solar Power

Although solar PV panels and water heater collectors work only when there's direct sunshine, both wind and water are available at any time of day or night. Wind, however, can come and go, from minute to minute. Water resources generally don't vary much over the course of a day, but they can vary over seasons and are also subject to droughts when there may be no power available at all for extended periods.

Historic context and future projections

Worldwide, the urban population is increasing by around one million people per week. This includes people driven in from the rural areas by an increasing frequency of droughts and floods and other probable consequences of climate change. The challenge to provide basic energy services for the larger number of city-dwellers in future, in order to provide an acceptable quality of life for everyone whilst also reducing greenhouse gas emissions, is daunting (not to mention providing clean water, food, sanitation and mobility). Increasing the contribution from local renewable energy sources, together with using energy more wisely and efficiently than we do now, will become a major part of the solution.

Climatic And Environmental Factors

Meteorological records and from agricultural and forestry practice supplies a valuable data base from which biomass energy systems can be conceptualized and developed. Of these three factors, precipitation has the greatest impact because droughts can wreak havoc on biomass growth. Fluctuations in insolation and temperature during normal growing seasons do not adversely affect biomass growth as much as insufficient water. Ambient carbon dioxide (C02) concentration and the availability of macronutrients and micronutrients are also important factors in biomass production.

Disadvantages Of Ac Subs

(1) MINIMIZE WATER USE The less water pumped, the less energy consumed. Low-flush toilets can cut domestic water use in half. (The Eljer Ultra-One one-gallon model is available nationwide.) Keep hot water lines short. Consider waste-water recycling. Consider drip irrigation to make extra-efficient use of water. Use water timers so that irrigation is not left on by mistake. Catch and store rain water for irrigation. Plant drought-tolerant species and use mulch to conserve water in your soil.

Chapter Water Resource Considerations

Water Resources The quality of the water is another important factor in identifying water resources. If the water will be used as a domestic water supply, treatment may be needed. However, water quality may be less important for livestock watering and irrigation unless it contains harmful chemicals. Saltwater, for example, can burn some crops and damage soils. For use in a domestic supply, surface water must be disinfected and may require additional treatment, depending on the content and sizes of particles (suspended solids) in the raw water. Human and animal activities can pollute surface water, which can contain silt and other particles from floodwater. Depending on the content of suspended solids in the raw water, it can be treated by first using a simple sedimentation tank and a slow sandfiltration system (in a rural water supply). Next, the treated water can be disinfected with a chlorine solution or gas or by using methods such as ultraviolet light disinfection or reverse...

What Is Geothermal Power

Steam plants Steam plants use steam or hot water resources (generally, hotter than 300 F). Either the steam comes directly from the source, or extremely hot, high-pressure water is injected into the well and then depressurized (flashed) to produce steam. The steam turns the turbines, which drive generators that produce electricity.

Renewable and Solar Energy Technologies Energy and Environmental Issues

Abstract A critical need exists to investigate various renewable and solar energy technologies and examine the energy and environmental issues associated with these various technologies. The various renewable energy technologies will not be able to replace all current 102 quads (quad 1015 BTU) of U.S. energy consumption (USCB 2007). A gross estimate of land and water resources is needed, as these resources will be required to implement the various renewable energy technologies.

Hydrothermal Features

Hydrothermal resources are categorized as dry steam (vapor dominated) or hot water resources, depending on the predominant phase of the fluid in the reservoir. Although the technology is similar for both, dry steam technology i s not included in this Technology Characterization because dry steam resources are relatively rare. Hot water resources are further categorized as being high temperature ( 200oC 392oF), moderate temperature (between 100oC 212oF and 200oC 392oF), and low temperature (

Land Water and Critical Materials Requirements

No land or water resources are required for operation of the system (Table 4), which is installed on existing structures and uses rainwater for cleaning. The only critical material for crystalline-silicon PV modules is high-purity silicon . Silicon is one of the most abundant elements in the earth's crust, so the issue is not availability but the cost of purification. High-purity silicon is typically produced as either pellets or chunks of fine-grained polycrystalline silicon and is commonly known as polysilicon feedstock.

Productivity in different environments

It would at least appear that schemes for ensuring quick recycling of the water added are as important as expansion of the irrigation potential, and that really significant increases in biomass production must involve oceanic water resources, either by marine biomass production or by use of (eventually distilled) sea water for irrigation. Some terrestrial plants actually accept sea water irrigation, with some reduction in conversion efficiency (Epstein and Norlyn, 1977).

Main Results Of The Medcsp Study

The MED-CSP study focuses on the electricity and water supply of the regions and countries in Southern Europe (Portugal, Spain, Italy, Greece, Cyprus, Malta), North Africa (Morocco, Algeria, Tunisia, Libya, Egypt), Western Asia (Turkey, Iran, Iraq, Jordan, Israel, Lebanon, Syria) and the Arabian Peninsula (Saudi Arabia, Yemen, Oman, United Arab Emirates, Kuwait, Qatar, Bahrain). The results of the MED-CSP study can be summarised in the following statements

Directly Powering Pumps and Motors

Water supply systems Solar power is very useful for water supply systems. The most common applications are for household water supplies and agricultural and livestock needs. Of course, using utility-provided water is more economical in most places, but in remote locations, it's simply not available. The pipes and trenches that would be required to get to the desired site are often prohibitively expensive. And in these types of applications, providing utility electrical power which you'd need to power your own pump is likely also prohibitively expensive, so there's a double whammy. Solar water pumps can be located anywhere there's available sunshine and a relatively clean water supply (dirty water may be filtered, but filters clog up, and the pump flow becomes constricted, so the application quickly becomes maintenance intensive). The water supply can be a well, creek or river, lake, and so on. i Available sunshine, in average hours per day, and your need for a consistent water supply...

Exploring Water Heating Systems

Passive systems use no pumps to move the water. (However, this definition comes with an asterisk. When you use the pressure from your cold water supply to drive your system, you still have a pump somewhere it just belongs to your municipality Or if you're on a well, the pump is deep within the Earth.) Passive means no pumps or moving parts are in the solar system itself. Passive systems are cheaper because they're simpler and have fewer parts. But they're also less versatile. Active systems, on the other hand, are capable of outputting more energy and working under a wider range of weather conditions. I explain a number of systems in the following sections, both active and passive.

Livestock Water Requirement

The average daily demand (m3 day) is estimated for the month of high demand or the wind design month (month with lowest average wind speed). Also, the demand must take into account any growth during the design period, which should be at least 10 years. The water demand for livestock can be up to 90 L day (Table 10.8). Evaporation from an open storage tank, especially in windy and dry areas, will require even more water. Also, animals will only travel a limited distance from the water source, so there needs to be one water source per 250 ha to harvest grassland. If the water supply and grassland are communal, then there is the distinct possibility that the growth in the size of the herds will result in overgrazing, especially close to the water supply. The domestic water depends on number of people, usage, and type of service (Table 10.9). What is considered necessary in some countries or regions would be considered a luxury in others. In addition, people will consume more water during...

Supplementing Your Domestic Water Heater

An electric water heater supplying a family of four uses 11.4 barrels of oil per year. That's more oil than that consumed by a medium-sized auto driven 12,000 miles per year, at 22 mpg, which uses only 11.1 barrels. When you install a solar water heater to supplement your domestic water supply, you're producing all the energy on site, in your collectors. There's no pollution at all. Tapping into your hot water supply

Introduction Wessex Water

Wessex Water is one of ten water and sewerage companies in England and Wales, covering Somerset, Dorset, Wiltshire and parts of Avon. Energy is one of the company's largest operational costs average electrical power use is about 27 megawatts (MW). The company has about 8MW of biogas combined heat and power (CHP) generation capacity, of which 4.5MW is continuously operating, provided by spark-ignited gas engines fuelled by digester gas. It also has some 550 emergency standby diesel engines, totalling 110MW of capacity, whose primary function is to power essential services such as sewage works and water supply works during power failures, which happen, on average, a few hours each year. Of this number, about 33 units, totalling 18MW, are also used commercially in a number of nonemergency ways that we call 'load management'. This includes routinely feeding power into the local electricity distribution system and, ultimately, the UK National Grid. These generators currently have a...

Calvin Benson cycle common to C and C plants

The advantages of the C4 plants over the C3 are maximum under conditions of high light power density, high temperatures, and limited water supply. These are the conditions found in semiarid tropical regions. Sugarcane, a tropical plant, for instance, is a C4 plant. C4 plants also outperform C3 plants when CO2 concentrations are low. During the last glacial maximum (some 20,000 years ago), the CO2 pressure in air fell to 190-200 atm. This caused grasses to replace forests in many regions. See Street-Perrott et al. (1997).

The convergence of power networking supercartels and the disempowerment of democratic institutions

The electricity supply is one of the essential infrastructure components needed to keep a modern society running, alongside the railway, the post office (including the telephone network) and the water supply. However, wherever regional electricity boards have been transformed into public limited companies, even where the state remains the majority shareholder, they have since begun using their regional monopolies as a springboard for moving into other companies and sectors where their activities are not so geographically restricted. This process has been underway for decades in Germany in particular, whereas the nationalized electricity industries of other countries have remained tied to their original business. The German federal monopolies commission has on many occasions criticized the expansion of the electricity industry into other sectors as a serious distortion of the marketplace.

Policy recommendations for local governments

I An assessment of available energy resources, together with analyses of future energy demands and costs of alternative supplies to meet heating, cooling, electricity and transport demands, should be undertaken prior to promoting the use of renewable energy. The assessment should include the potential for renewable energy projects based around water supply, wastes, and land managed by the local authority.

The Best Projects for DoItYourselfers

The ways you can create a solar fountain are diverse plus you get to work with all kinds of interesting physics. In this project, you can make something truly beautiful out of next to nothing. You can even use the technology to provide a domestic water supply for a remote cabin. (See Chapter 8 for details.)

Description of the Technology

Hydropower technology can be categorized into two types conventional and pumped storage. Conventional hydropower development uses the available water from a river, stream, canal system, or reservoir to produce electrical energy. With most conventional development, water is constantly available. A run-of-river development on rivers, streams, and canal systems uses the natural flow to produce electricity. Water releases from single-purpose reservoirs for power production can be adjusted to match electricity demands. Hydropower production is just one of many purposes for which the water in multipurpose reservoirs is used. Other uses can include irrigation, flood control, navigation, and municipal and industrial water supply.

Methanol can also be made by gasifying dried sewage sludge. Such a facility is already being operated in Berlin by the SVZ subsidiary (Sekundarrohstoff-Verwertungszentrum) of Berliner Wasser Betriebe, Germany s largest water supply and sewage disposal company, where sewage sludge is blended with brown coal for methanol production.

System Application Benefits and Impacts

The environmental impacts of generating electricity from geothermal resources are benign relative to conventiona l power generation options. Geothermal power generation does not produce the federally regulated air contaminant s commonly associated with other power generation such as sulfur dioxide, particulates, carbon monoxide, hydrocarbons, and photochemical oxidants. Some, but not all, hydrothermal fluids contain hydrogen sulfide and or high levels o f dissolved solids, such as sodium chloride. Thus, with geothermal hydrothermal power generation, the bigges t environmental concerns are the possible emissions of hydrogen sulfide and contamination of fresh water supplies with geothermal brines. Hydrogen sulfide emissions are abated, when necessary, with environmental control technology , and ground water contamination is avoided through protective well completion practices. Generally, there is les s possibility of adverse environmental impacts with hydrothermal binary generation than...

System Description

The reservoir subsystem is developed by drilling wells into hot rock about 4 kilometers deep, and connecting the wells through hydraulic fracturing. Water, from a nearby fresh water well or other source, is pumped through one or mor e injection wells into the reservoir, where it is heated by contact with the hot rock, and then recovered through two or more production wells. 4. A shallow water well to provide water (or other source of fresh water).

Installer Perspective

When we went to do the site survey at the Beckett home, we saw that it was not an ideal site. We were concerned, since they have a wood shake roof with many different planes, a solar hot water system, and some shading from trees. We gave Will the options on the layout, and he decided to put as many panels on his roof as possible. This worked out to be 28 of the AstroPower 120 W modules.

Passive Solar Hot Water

My husband and I live on the Salmon River in very rural Siskiyou County, Northern California. Our cabin is about half way between two of the three historic mining communities located on the river. All three towns and the mountainous areas surrounding them are off the power grid. We use primarily microhydro and are now incorporating solar into our system. In the past we've heated our house and water with wood. There are portions of each summer here when high fire danger allows no stove fires. You can't even use a chainsaw in the woods then. Just because we can't have stove fires doesn't mean we can't have hot water. Supplementing our wood stove heated water system we added an amazingly simple passive solar water heater.

Heat Recovery in Nonresidential Systems

Commercial industrial hot water systems offer many opportunities for employing heat recovery. Examples of possible sources of heat include air compressors, chillers, heat pumps, refrigeration systems, and water-cooled equipment. Heat recovery permits a double energy savings in many cases. First, recovery of heat for hot water or space heating reduces the direct energy input needed for heating. The secondary benefit comes from reducing the energy used to dissipate waste heat to a heat sink (usually the atmosphere). This includes using energy and energy expended to operate cooling towers and heat exchangers. Solar hot water systems are also finding increasing use. Interestingly, the prerequisites for solar hot water systems also permit heat recovery. After the hot water storage capacity and backup heating capability has been provided for the solar hot water system, it is economical to tie in other sources of waste heat (e.g., water jackets on air compressors).

We've touched on these a bit already. The real beauty of a free-circulating system is that it operates with no fuel or power costs although it needs a back-up system, like any other sunpowered heater, to come on whenever the weather's bad. Thermosyphoning solar hot water heaters are generally not as effective as forced circulators in providing a large and dependable hot water supply, but here are some of the very good reasons why people put them in

Use of renewable energy sources for heat and fuel production

Although the potential of solar thermal collector systems is enormous, their contribution to the global primary energy supply is still rather low. Assuming 70 million m2 of installed glazed collectors by the end of 2001 and an average heat production of 600 kWh m2, the total global solar thermal heat production was about 150 PJ. This is equal to 0.04 per cent of the global primary energy demand. China is by far the world's largest solar water heater manufacturer and user. By the end of 2002, the accumulated installed area of solar domestic hot water systems in China was about 40 million m2. Greece had a noticeable installed area per capita of 264 m2 per 1000 inhabitants by 2001. Projecting these per capita numbers to the global population, the total installed area would increase more than 20 times. Table 1.15 shows the number of installations of the countries with the most significant solar collector markets.

Governance by provision

I Tax credits, reductions and exemptions. Tax adjustments are not usually able to be made by local governments but where it is possible in some manner, then they can be a useful tool to encourage renewable energy equipment manufacturers, consultants, designers and researchers to establish their business centre in a city offering generous benefits. Other examples include property tax credits given by local governments for installation of residential (Belo Horizonte, Nagpur) or commercial solar hot water systems.

Types of Systems and Applications

System configurations can also vary significantly. Hot water systems for northern climates include glycol-based (anti-freeze) systems where the heat transfer fluid remains in the collector piping at all times. Draindown drainback systems use water for the heat transfer fluid and are drained whenever the temperature of the collector falls below a specified set point. Integral-collector-storage systems, In which the collector and storage components are both exposed to ambient conditions as a single unit, are also used in active snlar applications. Cooling systems may use the solar-generated heat to regenerate a desiccant wheel or to desorb the absorbent from the refrigerant in an absorption chiller.

Short History Of Solar Technologies

Probably the most familiar kind of solar equipment to most people is solar hot water systems, which provide domestic hot water, pool heating, and space heating. Solar hot water experienced an explosion of popularity in the 1970s, thanks to generous federal and state incentives made available under the Carter administration. Unfortunately, the flood of money, directed at a less-than-fully-developed technology and market, led to a Wild West atmosphere in much of the industry. A goodly number of badly made systems were

Constraints and Opportunities

Since OTEC is an emerging technology in its early stages, potential infrastructural constraints are yet to be identified. They may include (1) problems of integrating OTEC plants into island electrical systems, particularly if large OTEC plants are required to achieve economic performance (2) integrating OTEC fresh-water systems into existing systems, while providing maintenance or emergency storage or backup (3) integrating cooling systems with hotels, etc., while providing backup capacity and (4) coastal right-of-way access for large water systems, that will distribute water to users, including return flows to the OTEC plants. Environmental issues may also be involved.

The spurred impetus has been given to developing non pollutant vehicles, and consequently, the clean cars driven by the fuel cells loading proton exchange membranes (PEMFC), which based upon Nafion, have been surprisingly developed.

Schauberger Repulsator

A few years ago my so-called pioneering patents were applied for in 26 countries. In almost every country the patent assessors declared that I was mad and some of them even refused to evaluate the patent applications. Of these about half have been granted to date. The remainder are about to be granted, although their possible practical application has not been understood by a single patent assessor. The substantiation of these patent claims, however, could not be refuted in the preliminary assessment. During this period the German patent attorney, who had been preparing my foreign patent applications, told me that all at once there had been second thoughts and that my patents had been granted one after the other. The truth of my observation had thus been recognised as correct. Their granting was therefore compulsory. This change of opinion had been provoked by very strenuous counterarguments during the preliminary hearings as well as through the publication of various articles in...

Things that Work Alternative Energy Engineerings High Lifter Pump

High Lifter Pumps

My water system is comprised of a spring which flows into a large 480 gallon settling tank. From there, the water flows at 6 gallons per minute through 3 4 inch Schedule 40 PVC pipe 26 vertical feet to my pump site. The pump then pushes the water up 158 vertical feet through 1 black rolled drinking water pipe (only 1 2 inch pipe is required). The 250 gallon tank at the top is suspended between two sturdy conifers about 20 feet above the taps in my home to obtain sufficient indoor water pressure. the barrels and seals become scored allowing leakage. The High Lifter comes with a filter which takes out much of the harmful sized particles which may flow from your water supply. The filter must be cleaned regularly to avoid loss of inlet pressure. If a lot of foreign matter flows with your water, then the High Lifter may not be for you.

The Artificial Production of Springwater

Water Charge Experiment

I have small devices in my possession with which I can determine the quality of water. The ennobled water flows through rifled pipes without touching the sides, i.e. it falls through the middle and lands on cone-shaped, metallic bodies placed below the pipes. Wires are arranged around the outer periphery, which are cross-connected. They become charged with the animalistic currents emanating from the water and conduct them to an electroscope (see fig. 23 & figs. 1- 3). One litre of water has to pass through this apparatus about 150 times before the flapping of the electroscope's foils weakens. Neon tubes glow with a rich, dark red initially, only to become brighter and brighter until the water begins to die and the light finally flickers and goes out. Consequently we imbibe hundreds of thousands of volts when we drink this healthy water, which can in no way be differentiated from a high-grade mountain-springwater. It was in this way that I discovered how to transform stale...

Figure Overview of subsystems and components for SOFC and PEM systems

Anode Recycle Sofc Review

Figure 1-14 shows a simplified layout for an SOFC-based APU. The air for reformer operation and cathode requirements is compressed in a single compressor and then split between the unit operations. The external water supply shown in figure 1-14 will most likely not be needed the anode recycle stream provides water. Unreacted anode tail gas is recuperated in a tail gas burner. Additional energy is available in a SOFC system from enthalpy recovery from tail gas effluent streams that are typically 400-600 C. Current thinking is that reformers for transportation fuel based SOFC APUs will be of the exothermic type (i.e. partial oxidation or autothermal reforming), as no viable steam reformers are available for such fuels.

Pond Aeration Photovoltaic Powered

The Danciger system has large oxygen requirements for a number of reasons There are two ponds and two venturi diffusers. The location is at a low altitude (6300 Ft elevation) and warm climate. Seasonal drought conditions and lesser water inflow often contribute to warmer water temperatures.

Excerpts from Letter No to Josef Brunnader

As a result of experiments with the first two models, possibilities for their improvement and simplification emerged which were quite surprising, which I will tell you about in more detail in the near future. This will be from Germany, where I am making more rapid progress, because there water scarcity is looming increasingly threateningly and therefore the authorities will be forced to make drastic changes. Indeed, in this whole sphere little can be done without compulsion.

Small Hydropower Technology

Hydropower is the energy and power obtained from running water. Water resources vary widely in regional and local patterns of availability. The supply is dependent upon topographic and meteorological conditions as they influence precipitation and vapotranspiration. Quantities of water stored are dependent to a large extent on the physical features of the earth and on the earth's geological structure. The amount of energy produced at a specific site is directly prnpnrtinnal tn the amount of flow and the available head.

A The Hydrogeology of New York City

Brooklyn Queens Aquifer

The geology of Brooklyn and Queens is very different from the geology of the other boroughs. Where The Bronx, Manhattan and parts of Richmond are predominantly underlain by bedrock with little if any soil covering the rock surface, most of Queens and Brooklyn have very thick surficial deposits of unconsolidated material overlying the bedrock basement. These deposits range from clay to gravel and are from zero to over 1,000 feet deep. The sand and gravel aquifers include the Upper Glacial, Jameco, Magothy and the Lloyd. These aquifers areall extensively used as sources of ground water for eastern Long Island. The most widely used aquifer for municipal water supplies is the Magothy Aquifer. The Lloyd aquifer is the deepest aquifer, directly in contact with the underlying bedrock. The Lloyd is a restricted use, protected, aquifer only available for use by communities that have no other option for a water supply, such as barrier island communities that find their shallow wells become...

Geodomes Camera Ready Inches Wide By Inches High

Water System The pipe that drops from the well top down to the pump is called drop pipe . We use flexible black polyethylene pipe. Get drinking water grade pipe, not utility grade pipe or irrigation tubing. It should have at least a 100 psi rating. This flexible pipe allows easy installation and removal by hand, without the need to disassemble joints every 20 feet. Water well professionals are accustomed to larger 120 240 vac pumps and use one inch pipe or larger, of a thick, rigid variety. This type of pipe is not appropriate for these pumps. The low power pump will not kick when it starts, so it does not require heavy-wall pipe (or a torque arrestor) for support. Wire for low voltage power transmission must be relatively large and expensive to minimize power loss. If the distance from your home's power center to the well and down to the pump is more than 200 feet, the expense may be high. A dedicated system may be cheaper, particularly if batteries are eliminated. This is called PV...

Solar thermal domestic water heating systems

Thermosiphon Flat Plate Schematic

The heating of domestic water involves much higher temperatures than for swimming pool water. The simple absorbers used for swimming pool heating are in most locations not suited to domestic hot water systems because the absorber losses due to convection, rain and snow as well as heat radiation are unacceptably high. Domestic water heating systems typically use collectors that have much lower losses at higher water temperatures. These are either flat-plate, evacuated flat-plate or evacuated tube collectors and are integrated with collector storage systems. Collectors for domestic water heating are described in the section on solar collectors, p85. A complete system for domestic water heating consists not only of a closed collector to heat the water. Further components such as a hot water storage tank, pump and an intelligent control unit are needed to ensure a hot water supply that is as comfortable as we expect from conventional systems. A system where the water flows directly...

Baseline Potential with RDD

Additional hydroelectric power sources that were not considered in the NHS or FERC resource data include those projects that require additional R,D&D to further develop the equipment and technology. For example, the use of free-flow turbines in flowing rivers has been estimated to have a potential of 12.5 GW. This concept is unique in that very little civil work is required, and the plant can be installed without creating a water impoundment area or disrupting flow. Equipment has been developed, but the concept should be tested. Irrigation canals, domestic water systems, ultra-low-head (less than 10 ft) sites, and small-scale sites (less than 1 MW) may also provide additional resources. It is estimated that these projects could provide an additional 5 GW. R,D&D to develop new, inexpensive equipment is needed to make these sites feasible. Therefore, it is estimated that the baseline potential can be increased by 17.5 GW with an aggressive R,D&D program.

Water Pumping with Solar Electricity

The two major water systems for domestic use divide by water source. If your water source is shallow (less than 15' vertical) from your pump location, a shallow well or surface pump will suffice. These pumps are less expensive, operate at low voltage DC and are of positive displacement design which increases overall system efficiency.

Solar Powered Water Pumping

A quiet revolution is taking place in the way water is pumped beyond the electric power lines. Solar power provides a welcome alternative to fuel-burning generators, cumbersome windmills and tedious handpumps. Over 20,000 solar pumps are in use throughout the world. Most of them are small systems for remote homes, livestock and village drinking water. Solar pump controllers deliver high current even in low light conditions by increasing the current at the expense of lower voltage (the electronic equivalent of low gear). This automatic transmission allows pump operation throughout the solar day, however slowly, even in moderately cloudy conditions. These controllers are known as maximum power point trackers or linear current boosters . A system designed for reliable output in cloudy climates may have an oversized array to assure a more constant water supply. A water system with a very deep well or one that's distant from the house will often use a low-flow solar pump at the water...

Excerpt from Patent Letter to Munich Patent Office

By reason of research work carried out over more than 30 years, I can provide irrefutable proof that centrifugal acceleration triggers off decentrating, reactive forces. Through the hitherto unnoticed, instantaneous pole-reversal in the lower world of bipolar basic elements, decomposive forces evolve in the media of water and air. This results in the killing off of noble bacteria. In the dying water symptoms of decay appear and pathogenic bacteria come to life, leading to the development of cancer. For this reason the unreal systems of motion taught in all universities are the true cause of cancer. Plasmic disturbances occur, which for lack of adequate replenishment of qualigen, lead to the death of the cells, if metallic toxins form on the cellmembrane. This happens as a result of the accumulation of certain metal ions, to which the oligodynamic extermination of pathogenic bacteria by silver ions is also attributable. These do indeed disinfect the contaminated water, although further...

Chapter Selecting Power and Sizing Renewable Energy Water Pumping Technology

Ethiopia Water System Distribution

Wind has been a traditional energy source for centuries and is still commonly used in many developing countries. It has been harnessed to separate grain from hay and to sail boats. Since the early 13th century, wind has been used to pump water to dewater polders in the Netherlands. Small wind pumps, made of wood, have been used in France, Portugal, and Spain for pumping seawater to produce salt. Then the American wind pump, made of steel with a multibladed fanlike rotor, became the most popular water pumping technology. It was introduced for domestic water supply and railroads in the late 19th century and later used to water livestock in the early 1900s when millions of cattle were brought to the North American Great Plains. During the last 100 years, more than 8 million windmills have been manufactured in the United States, and the design has proven so successful that it has been copied around the world. Today more than 1 million windmills are in use, mostly in United States,...

Ram Pump Calculations

Ram Pump Calculator

Figure 8.9 shows the general layout of a pumping system using a hydraulic ram. The water supply flows down a strong, inclined pipe called the 'drive pipe'. The potential energy MgH of the supply water is first converted into kinetic energy and subsequently into potential energy mgh. The kinetic energy is obtained by a mass of water M falling through a head H, and out through the impulse valve V . Operation is as follows Such considerations have led to an almost complete cessation of dambuilding in many industrialised countries, where the technically most attractive sites were developed decades ago. Indeed in the USA, dams have been decommissioned to allow increased 'environmental flow' through downstream ecosystems. However, in many countries, hydroelectric capacity has been increased by adding turbine generators to water supply reservoirs and, for older hydropower stations, installing additional turbines and or replacing old turbines by more efficient or larger capacity modern plant....

Biodiesel In Cambodia

Jatropha is a perennial shrub native to subtropical regions, notable for its high-oil-yielding seeds and ability to grow in regions prone to severe drought. It has been gaining much attention in Southeast Asia for its potential as a cash crop. It grows fast in full tropical sun, up to 5 meters tall with a tough stem, thick succulent leaves, and lime-sized fruit containing five oil-rich seeds. One hectare of Jatropha can yield more than 1 ton of seeds per year, or more than 1,500 liters of oil, depending on rainfall.

Be Sure That The Ampacity Rating Of All Wire In A Circuit Meets Or Exceeds The Fuse Protection Rating Of The Circuit

Locate batteries, inverter, ac battery charger, and distribution panel near each other. Also, locate the distribution panel as close as possible to very large loads and as central as possible to all other loads. This will shorten wire runs and for some circuits, reduce the wire size required. Water Well Pumps Consider a slow-pumping, low power system with a storage tank to accumulate water. This reduces both wire and pipe sizes where long lifts or runs are involved. An ARRAY-DIRECT pumping system may eliminate a long wire run by using a separate PV array located close to the pump. (For more about water system design, see our article Solar Powered Pumping , HP 11.)

The generator can power loads too large for the inverter. It can also recharge the system's batteries via the charger built into the inverter. Roger and Ana's well uses a submersible 240 vac water pump to fill a large cistern which gravity flows the water to the house. The generator supplies 240 vac for the pump. Roger is investigating putting his water supply on solar too, but that's another story

Energy and the Economy

Available in the energy sector, allowing for a transition to low-carbon venting pathways. Given the current composition of the energy sector, this is unlikely to happen overnight but rather through a series of decisions over time. Adaptation decisions have begun to address current climatic risks (e.g., drought early-warning systems) and to be anticipatory or proactive (e.g., land-use management). With increasing climate change, autonomous or reactive actions (e.g., purchasing air-conditioning during or after a heat wave) are likely to increase. Decisions might also break trends, accelerate transitions, and mark substantive jumps from one development or technological pathway to another (Martens and Rotmans 2002 Raskin et al, 2002a,b). Most studies, however, focus on technology options, costs, and competitiveness in energy markets and do not consider the implications for adaptation. For example, McDonald et al.(2006) use a global computed general equilibrium model and find that...

Energy and the Atmospheric Environment

Even though the natural circulation in the atmosphere provides scavenging effects, continuous and long-term loading of atmosphere might lead to undesirable and dangerous situations in the future. Therefore, close inspection and control should be directed toward various phenomena in the atmosphere. Among these there are more applied and detailed research needs in order to appreciate the meteorological events in the troposphere, ozone depletion in the stratosphere, pollution in the lower troposphere and trans-boundary between the troposphere and hydro-lithosphere, energy, transport and industrial pollutants generation and movement, effects of acid rain, waste water leakage into the surface, and especially ground water resources. It has been stated by Dunn (1986) that several problems have arisen from the increased use of energy, e.g., oil spillages resulting from accidents during tanker transportation. Burning of various energy resources, especially fossil fuels, has caused a...

Letter to Dr W Busselberg

In the periodical TAU you will see the treatise on water resources management.4 Your desire for further articles I am unable to satisfy, because these writings have been suppressed everywhere. I have only one copy of each, and The publication or the manuscripts concerning the decomposition of drinking water, domestic water, blood, and the cause of cancer are so alarming that it is unwise to speak of them here in Germany. The whole secret of all scourges is to be ascribed to over-oxygenated water - water that has been treated with chlorine, quartz lamps, or subjected to oligodynamic processes. When combined with anodic substances (artificial fertilisers), such water produces bacteria in a very short time. I have furnished doctors with evidence and set down the necessary interrelations in writing, because nobody has dared to publish the true causes, otherwise almost all drinking water supply-pipes would have to be rebuilt. Equally inevitable would be the prohibition of the fertiliser...

Energy and sustainable development Principles and major issues

Effect1 and lead to significant climate change within a century or less, which could have major adverse impact on food production, water supply and human, e.g. through floods and cyclones (IPCC). Recognising that this is a global problem, which no single country can avert on its own, over 150 national governments signed the UN Framework Convention on Climate Change, which set up a framework for concerted action on the issue. Sadly, concrete action is slow, not least because of the reluctance of governments in industrialised countries to disturb the lifestyle of their voters. However, potential climate change, and related sustainability issues, is now established as one of the major drivers of energy policy.

Chapter Lessons Learned

As renewable energy technologies continue to evolve in terms of efficiency and cost reduction, more and more systems will be installed in many developing countries. Renewable systems are becoming even cheaper than conventional systems, especially for small to medium applications. Using wind and PV systems for village home systems (such as for solar home systems and battery charging) is cheaper than the traditional kerosene or car battery lighting systems. Similarly, use of renewable technologies for water pumping applications becomes more attractive for rural water supply, livestock watering, and small irrigation systems. Systems installed in the last decade have demonstrated that well-matched wind or PV designs based on proper resource assessment can operate reliably with minimum maintenance.

Weighing your options

You can design a system reasonably well without professional guidance. Still, climbing around on a roof and soldering pipes isn't for everyone. In addition to your own skills, here are some factors to consider when deciding whether to install a solar water system on your own

Completing the flow system with valves and monitors

L Drain valves Drain valves are part of every solar water system because they are the means to drain the fluid out of the system (maintenance, weather safety, and so on). Ball valves are most reliable they use a spinning ball with a big hole, constrained in a socket. They're either on or off.

Environmental analysis

Legionella can multiply significantly in domestic hot water systems and thus become a danger for human beings if they get in contact with the infected water. However, this is not a problem specific to solar systems, but this problem has also occurred in solar systems in the past. As legionella die quickly at a temperature of approximately 60 C, this danger can be easily limited by appropriate technical measures. Tests have also shown that extended storage periods, exceeding by far the requirements of DVGW recommendation (German Association for Gas and Water), do not necessarily lead to a multiplication of legionella 4-22 . If the corresponding DVGW regulations are observed, the multiplication of legionella can be safely avoided. These requirements have been fulfilled for all modern solar systems. Out of the system layouts analysed in this chapter, this problem might only occur with regard to the system SFH-III having domestic hot water storage. In all other systems legionella will...

How Should You Insulate Your Storage Tank

How much insulation is enough It's theoretically impossible to over-insulate a solar hot water system, but here are some minimums There should be at least 3-1 2 inches of fiberglass insulation or its equivalent behind the absorber plate in the solar collector, as we already know. There should be at least 1-1 2 inches of insulation on all pipes in the system, and there should be at least 6 inches of insulation around the storage tank.

Forced Circulation Systems

To keep things simple, we'll divide the heater into its three major parts (1) the collector loop, (2) the hot water loop, and (3) the thermostatic controls. Then, we'll trace the flow of antifreeze fluid from the storage tank (beginning at the very base of the collector loop), to the collectors and back through the heat-exchanger coil. Next, we'll follow the path of the water, beginning at the cold water supply, as it goes through the solar storage tank and existing hot water tank, to the house itself. Finally, we'll explain how the control system operates.

Resource Sustainability

Large scale biofuel production is not only energy intensive but it could have an adverse environmental and social impact. Such development requires substantial water resources with the result that water tables in areas of intense cultivation have been lowered to unacceptable levels. Expansion of biofuel crops could also speed up tropical deforestation with the associated lowering of CO2 absorption and threat to extinction of thousands of species of animals and plants. If such crops are encouraged through subsidies, food shortages may occur if land previously used to produce food is lost. It could be concluded that the biomass path, unless used wisely, may cause serious environmental impacts.

Public Sector Perspectives On Renewable Energy Economics

When calculating the costs of projects, taxes are generally iynored, because they du nut represent real resource costs needed to develop a project. However, when discussing taxes, we should distinguish between distributive and allocative taxes. Distributive taxes are, essentially, ways that governments appropriate part ot the rents ot a given project that is, they simply distribute rents from one group to another. Allocative taxes, on the other hand, could be viewed as payments for government services. An example might be property taxes that pay for water supply. When doing a benefit-cost analysis, it is important to distinguish between these two types of taxes because the latter group, allocative taxes, actually are payments for real resource inputs often called social infrastructure.

Gemini Space Missions

The main electrical power source for the two-man Gemini vehicle was an ion-exchange membrane fuel cell built by General Electric under contract by McDonnell Aircraft Corporation (Oster, 1962). The hydrogen and oxygen reactants were stored cryogenically, and the water product was used as drinking water for the crew on long missions. The first mission with the fuel cell was Gemini 5, which flew August 21-29, 1965.

Other Applications

The first practical application of fuel cells was in space, where reliability far outweighs cost. The cells work with the hydrogen and the oxygen already available for other uses in the spacecraft and provide valuable drinking water as an output. GE SPFCs started the trend at the moment AFCs are more popular they were used in the Apollo program and currently supply energy for the space shuttle and for the International Space Station.

Cattle Saloon

He erected a stationary module mounting rack onto the frame of an abandoned house trailer. Don's quiet generator uses Solarex modules wired in two series parallel arrays. After passing through a controller the current powers a DC motor which turns a Solarjack pump jack. The unit is used at two separate locations during all kinds of weather. Heavy turnbuckles latch the trailer firmly in place. Each water well is fenced to keep cattle at a safe distance. It's many miles of hard riding in unbelievable chill factors from the main ranch house to either well. The winter range normally has plenty of grazing and shelter for cattle. With ground heat stored in the massive concrete cisterns and trough, seldom does Don have to chop ice for livestock. Critters need water even in cold weather. They do much better when their drinking water is reasonably warm.

Energy Cascade

This is important not only for turning salt water into drinking water (distilled water), but the unit can also do water pasteurization (see the solar puddle article). Further, the solar distillation unit will be a very important part of our system to make ice by chemical methods as well as for the harvesting of moisture (water) from the air.

Our home doubles as an eating area and office for the Cape Tribulation Tropical Research Station, operated by the Australian Tropical Research Foundation. Behind it is a 30 m (100 foot) high gully with a stream that only flows during the wet. At the top is a small permanent spring which provides our drinking water. During the wet, this gully fairly cascades with water

Richmond County

The outwash deposits located in eastern Staten Island are similar to the outwash deposits found in southern Brooklyn and Queens. Both units are capable of ground water yields in the hundreds of gallons per minute to thousands of gallons per minute. However, unlike the Long Island outwash deposits, the outwash on Staten Island are limited to a maximum of 125 feet. The proximity of the outwash deposits to New York Bay places this aquifer in danger of salt water intrusion from over pumping. Therefore, a system of five New York City drinking water wells was limited to pumping less than 5 million gallons of water per day, although the wells were capable of significantly higher yields. These wells have not been operated since the early 1970's. Geothermal systems return the water pumped out to the aquifer, so they should not increase the risk of saltwater intrusion. Salty or contaminated water will increase the maintenance required for wells and well pumps. The Palisades Diabase is...

Power to the People

One late night about a week into the project we were awakened by 2 earth shaking explosions. The next day we found that the Contras had blown the main power lines 15 miles from where we slept. These were no firecrackers. Much of Northern Nicaragua was down. When we left for Managua a week later, the only evidence of electricity I saw was at our project. A striking impression was that of hundreds of people hauling drinking water on their backs for miles. The city's water treatment plant is electrically operated. Two facts were evident 1) the real burden of terrorism is born by the common people, and 2) those of us that produce our own power are free indeed in times of civil strife.

Third World

Thirsty Did you get some water from a lake and don't know if there are little buggies floating in there that will cause stomach problems or an infection Put the water in the solar oven and get the water to 160F+ for at least six minutes. This will pasteurize the water and kill all but the most hearty of microbes (like what might be growing in a swamp). Boil the water boil (212F) in a solar oven for five to ten minutes will kill everything. You can install a distillation column (see elsewhere in the book) attached to the solar oven (like what's on top of a moonshine still), and you can distill off the water vapor, condense it, and the water will be about as pure as fresh rain. Even more, you can distill your own urine. Put a bucket of urine in a solar oven, boil the liquid, distill off the water, and drinking water will be produced. The only thing left will be heavy salt water. Fresh urine is sterile, with no bacteria. The nitrates and minerals in our urine are food for bacterial...

Energy and Society

Although an adequate supply of energy is a prerequisite of any modern society for economic growth, energy is also the main source of environmental and atmospheric pollution (Sect. 1.6). On the global scale, increasing emissions of air pollution are the main causes of greenhouse gases and climate change. If the trend of increasing CO2 continues at the present rate, then major climatic disruptions and local imbalances in the hydrological as well as atmospheric cycles will be the consequences, which may lead to excessive rainfall or drought, in addition to excessive heat and cold. Such changes are already experienced and will also affect the world's potential for food production. The continued use of conventional energy resources in the future will adversely affect the natural environmental conditions and, consequently, social energy-related problems are expected to increase in the future. A new factor, however, which may alleviate the environmental and social problems of future energy...

Pwag g

Starting from this assumption, the power PWa resulting from the respective water supply can be calculated using Equation (2.25). qWa is the volume-related flow rate. According to this formula the product of flow and utilisable head basically determine the power of the water. Large heads can generally be achieved in mountainous areas, whereas in lowland areas mainly the flow assumes high values. A certain water volume VReservoir can be held back in times of high precipitation. Also for that type of storage, the water resources equation (Equation (2.21)), including inflow, outflow, and occurring leakage and evaporation losses, applies. Additionally the discussed conditions apply to the power and work that can be provided by the reservoir. The power depends on the time period required for emptying the reservoir. The stored energy EWa is defined by the size of the reservoir and thus by the stored water volume and the utilisable head. Equation (2.26) applies.

States) that was the focus of the ASP. Several quads (10 Btu) of fuels were projected for the various available resources. Other areas, from Florida to California, could also be considered. Microalgae systems actually use fairly little water, compared to irrigated crop plants. In addition, many waste and saline water resources may be available and suitable for microalgae production. Many CO2 sources are available, and algal ponds could be purposefully co-located with CO2 sources, or even vice versa. This is already being done at a commercial microalgae facility in Hawaii.

Controlling the sunlight in your house is easy and inexpensive, and it can have a major impact. You can heat water with the sun any number of ways to help around your house. When you understand your home's ventilation schemes, you can install solar fans and make your house much more comfortable, as well as keep the monthly power bill down. And you can buy solar systems that can power your boat, RV, or remote cabin. I also touch briefly on wind and water resources, the neglected cousins in the solar power family.

Previous Work

The earliest published geological information on the Hot Springs Mountains is the report on the geology of the Fortieth Parallel (King, 1878). Russell (1885) briefly described the area in his famous monograph on Lake Lahontan. Vanderburg (1940) compiled information on the mining districts of Churchill County and gave a brief description of activities in the Desert district, which lies in the northeastern portion of the Hot Springs Mountains. Axelrod (1956) mapped a small portion of the Hot Springs Mountains in detail while studying the fossil flora of the area. His work represents the most detailed compilation of stratigraphy and structure to date. Geologists of the Southern Pacific Land Company conducted reconnaissance field mapping and mineral occurrence inventories in the 1950's and early 1960's (unpub. reports of Southern Pacific Company). Harrill (1970) conducted a water resources appraisal of Granite Springs Valley and surrounding areas, which includes a part of the Hot Springs...

Hydropower Energy

Another possible conflict between adaptation and mitigation might arise over water resources. One obvious mitigation option is to shift to energy sources with low greenhouse gas emissions such as small hydropower. In regions, where hydropower potentials are still available, and also depending on the current and future water balance, this would increase the competition for water, especially if irrigation might be a feasible strategy to cope with climate change impacts on agriculture and the demand for cooling water by the power sector is also significant. This reconfirms the importance of integrated land and water management strategies to ensure the optimal allocation of scarce natural resources (land, water) and economic investments in climate change adaptation and mitigation and in fostering sustainable development. Hydropower leads to the key area of mitigation, energy sources and supply, and energy use in various economic sectors beyond land use, agriculture, and forestry.
