Jacobs Wind Generator

N 1989 Jordan College Energy Institute (JEI) formed a partnership with Western Michigan University (WMU) to build and race a solar powered car, the Sunseeker, in the 1990 General Motors Sunrayce from Florida to Michigan. JEI had expertise in building light-weight racing vehicles. Despite an acute lack of funds, our entry, the Sunseeker, came in eighth in a field of thirty-two. The cars designed for this race are, of course, not suitable for everyday driving, but they do have some lasting...

Automagic Battery

WE MAKE WATER FROM YOUR GAS Hydrogen and oxygen battery gas catalytically recombined into pure water and returned to each battery cell. Keeps battery topped off for extended periods of time and reduces maintenance costs. Explosive hydrogen gas is virtually eliminated from the battery area. Corrosive spray and fumes are contained and washed back into each battery cell. Electrolyte kept strong longer, extending the useful power and life of the battery. HYDROCAP Vents simply replace the battery's...

Stereo Hell

Dear Richard, I am writing you in regards to our phone conversation last month concerning my trouble running my new stereo system. As you may recall, I had purchased a new Pioneer receiver(model VSX-37005) and CD changer (model PD-M430), and was attempting to run these on my Trace 2012 inverter. The CD changer worked fairly well on the inverter power. It did however require an external power switch to eliminate it as a phantom load and to prevent it from doing funny things when the inverter was...

Percent Increase In Windpower From Ft Reference Height

This Let's start back down in the other direction and find out what our minimum tower height might be. As the wind passes over the ground, it bumps into trees and houses and passes over hills and valleys. All of this causes friction between the wind and objects on the earth, resulting in the slowing down of the air mass. Because air is a fluid and reacts similarly to water, we can look at a stream to see this phenomenon in action. Water along the bank swirls and eddies around, while the water...

Gas Forge Diagram

An electric powered blower can be installed in the induction tubing just after the burner outlet. This will provide vacuum to start the burner and will feed fuel gas to the engine so that it can be started and run. The disadvantages are that the blower will be subject to the high heat and unconditioned gas leaving the generator. This will destroy the blower. Moving the blower downstream to the other side of the gas cooler might seem to be the solution here but you will find that the low vacuum...

We live in southwestern New Hampshire, and the weather often brings extremes of temperature and wind. Our home site is high on a hill top, open to the winds, and far enough from the utilities that commercial power has never been an option. My concern and reason for writing this is the increased interest in wind power that I see in Home Power. PVs are easy to live with. Once installed, they just sit there and work. Maybe PVs need cleaning once a year, or the snow swept off on occasion. Wind...

Good Chip Usal, You wrote of having trouble with a Technics turntable on Trace inverter power. I am surprised, and wonder if the noise is electrical noise producing sounds in the speakers with the music, or if it is physical noise from the turntable transformer and mechanism directly Back before there were small low cost efficient inverters, we used to convert Technics turntables to operate directly from 12 volt DC power. We did this to save power and make economical turntables available to...

Specific tasks require electric power. The better we know our appliances, the better we can estimate the amount and type of electric power we need. The emphasis here is on planning ahead and this saves thousands of dollars in overall system costs. Deciding which appliances are appropriate for electric power, and which are not. Selecting the most efficient appliance to perform a particular task is critical. Efficient appliances cost more to buy, but they are much cheaper to OPERATE. Before all...

Another path to a similar result is to heat wood in a closed container until it is hot enough for the chemical bonds holding the hydrogen and carbon together to break. This is destructive distillation, a quite different process from that of combustion since no outside oxygen is introduced. You might think that such a device would produce only hydrogen gas and carbon But that is only because I have kept this explanation oversimplified for clarity. The products of this process will depend on the...

The Pan American Health Organization is committed to eradicating polio in South America before the turn of the century. Solar energy is playing a major role in this campaign. Here is a story of how three Colorado solar educators are helping introduce photovoltaic technology to improve rural health care. PV powered refrigeration is the key. Polio once took the lives of hundreds of American children each year and left thousands crippled in its wake. That was until a vaccine was discovered in...

I live in a small town on the North Coast of California. We joke about being on the edge of the continent, but power lines run down Main Street and I get most of my power the easy way from the grid. We get some weather up here, and it takes the power out regularly a dozen times a year, sometimes for a day at a time, and so I put quite a bit of thought into surviving the times we are on our own - gas cooktop, passive solar and wood heat, gravity fed water, solar hot water. Kerosene lighting is...

Low Pressure Gas Storage Tank With Water Seal

Opslagtanks Biogas

Counterbalanced to control the pressure of the gas inside. Fuel gas is pulled from the gas generator by a simple centrifugal bower, which forces it through the conditioning stages and into the storage tank under pressure. It is desirable but not necessary to have a storage tank even if the gas is to be immediately used as fuel. Such a reservoir maintains a buffer supply of gas to even out any fluctuations in supply and provides an even, controllable supply of pressure to the end device. It also...

Electric Fence Schematic

Resistor potentiometer networks shown in the schematic, then your Time Machine will produces pulses as per the Timing Table shown above. This means that the pulses can occur as slowly as very ten seconds 0.1 Hz. , or as rapidly as one hundred thousand times per second 100 kHz. . This also means that the pulse can last as long as ten seconds, or as short as ten millionths of a second 10 js. . And this covers the frequency and pulse duration ranges needed to efficiently control even the most...

From a woman's point of view I have found that a lot of people mostly women are surprised that an elegant home may be maintained on renewable energy. Somehow the idea that renewables mean primitive or spartan living has been accepted, mainly by grid users. Comfort, style, amp function are all possible. Home power systems are available for every style of living, from small to full-sized family uses. This home is located 2.4 miles from the closest grid power. To bring power in would cost...

Copper Cricket Solar Water Heater

I have only one design principle apart that it should work whenever I engineer anything it should be simple. Thus I was deeply smitten by the concept of the Copper Cricket Solar Water Heater when it was first described in these pages HP 8 . It was the design I was waiting for to substitute the sun for our water tank's electric heater. No pumps, no electricity, no wires, no relays, no solenoids, NO MOVING PARTS -- and it would pump from the roof 30 feet above my tank in...
