It when the controller's light was red. This confusion originated from the previous experience of the locals running DC televisions off car batteries they used the batteries until they were dead. After some conversations concerning long-term battery health, I left the village with the confidence that the locals were up to the job of maintaining the system, and that solar electricity would thrive in the rugged hills of Las Pintadas.

Source Renner Petroleum, Eureka, CA Source Renner Petroleum, Eureka, CA The first thing I learned was, don't mix it yourself in your tank at home. If you decide to convert to biodiesel, first flush your tank of all the old dino diesel. Biodiesel has more solvent action than regular diesel. This means that when you blend it in your tank, it will ungunk all the sludge that is in the tank. An older tank will have an accumulation of rust, caused by moisture in the tank, and residue from impurities...

Our otherwise all-electric house came with a forced-air heating system driven by a 30-year-old Chrysler AirTemp, oil-fired, counter-flow furnace. It is a sturdy behemoth no longer manufactured, inefficient by today's standards, but in pretty good shape. This is not a unique story a quarter of all furnaces in use in the U.S. are more than 20 years old, inefficient by today's standards, yet still operating. Our furnace burned red diesel 2. Initially, we didn't want to think too much about burning...

Have Your Say

For a long, long time, energy activists have been looking for ways to turn our nation's dismal energy policies around. Watching our leaders promote dirty energy technologies instead of dealing with the real environmental, social, and economic problems that our energy policies contribute to has been frustrating and disheartening. Mainstream and lesser known environmental groups, individual activists, and renewable energy users have provided only stopgap measures, and have not been successful...

Inductance

Derivation From Latin inducere, to lead, bring in, induce. When you connect the positive and negative leads of a generator, battery, or other energy source to each other with nothing but wire in between, all the charges try to flow at once, with nothing but the size of the wire to stop them. This rush of charge (high current) is called a dead short or short circuit, and it's not pretty. It can lead to melted wires, damaged equipment, and fires. Electrical loads in a circuit provide a form of...

Info

I explained to the students that the voltage to the pump varies with the sunshine, and determines the speed of the motor. The torque load on the motor (how hard it is to turn) determines the current draw, and that is determined by the height of the water lift. We watched the voltage vary with the sunshine. The current stayed constant, as expected, because the height of the water lift doesn't change. The pump is supplied with a low-water probe. If the water level drops lower than...

However, Andrew has assured me the tubes will never freeze before the tank due to the natural thermosyphoning effect and the fact that ice will always form at the top of the system. Water is at its maximum density at 39 F (4 C), so the freezing water always rises to the top. The volume of the tank (at least half full) would require subzero temperatures to freeze. These units are common in China, where they use them in heavy freeze areas with the only freeze problems being the water in the send...

Since the mid-1980s, I've been designing passive solar homes for the midwestern United States. When I decided in 1999 to run my home office on solar electricity, I knew the supply and demand balancing act would be similar to passive solar design. I would have to make my office much more efficient and incorporate lots of electricity storage to get me through a week or more of continuously cloudy weather during winter. Motivated to be freed from responsibility for my share of the pollution caused...

Lately, I have heard that Congress is considering an energy bill that would give oil and gas companies billions of dollars in tax breaks and other incentives. They are also said to be reconsidering drilling in ANWR, and opening more federal lands to oil and gas exploration. This is totally outrageous. These companies have more than enough capital to invest on their own. They don't need any public money. This money would be better spent on installing billions of watts of solar and wind power...
