Electricity for Beginners Resistors Diodes

The last Electricity for Beginners article in Home Power 31 used a plumbing analogy to explain how current flows in parallel and series circuits. We looked at Kirchhoff's Laws which tell us how to predict how much current will flow in different legs of a circuit. Now let's look at the fun part the pieces and parts that you can fit together to build circuits. Playing with these electronic parts is to play with one of the pleasant successes of capitalism. These little pieces are cheap, and you...

With today's cheap power, it is impossible to justify CCAT's solar and wind electrical system on money alone. The electrical system serves as an engineering political statement, as an education tool, and as a center for ecological R& D. On the other hand, CCAT's solar water heating and space heating systems are cost effective, even in today's energy glut. During sunny periods, water is heated by an active solar thermal system. One of CCAT's first projects was construction of two flat plate...

It's a whole lot easier to Alternator peak your alternator output after Field changing or shutting down nozzles with the rheostat than by changing out fixed resistors. The biggest problem that many hydro users have is overcharging. Eat your heart out, PVers With a constant 24 hour, 365 day power source, a battery bank should be looked at as more of a flywheel than...

The Paez

The Paez Indians live in southern Colombia in a mountainous land called Tierradentro literally, the land within. As befits a region with such a romantic name, their 200,000 acre homeland is isolated, rugged, remote, and scenic. Scattered throughout the mountains are 20 villages and 300 small settlements, home to approximately 45,000 people. The five largest villages have electricity the rest are unlikely to ever be connected to an electrical grid, because the landscape is too rugged and the...

Urban Sustainable Living

In 1978 the building was not remarkably different than thousands of American houses. Like most houses, it wasn't energy efficient gas and electricity were cheap. It dumped its waste directly into the city's sewer system. The food that its occupants ate was purchased from distant markets. Perhaps the only thing that distinguished this house on 16th Street and Cluster Lane in Arcata, California, was its scheduled demolition as part of an expansion of Humboldt State University HSU . The history of...

The Homebuilt Dynamo

Forbes reviewed by Mark Newell The Homebuilt Dynamo book presents complete details for what I consider to be the ultimate in homebrewed power projects building my own low rpm revolution per minute generator. A low rpm generator is ideal for simple and efficient generation of electricity from sources that often are in the 100 to 800 rpm range such as wind, hydro or, as Alfred and Julia Forbes do for their daily electric needs, a bicycle. As Alfred says himself, The Homebuilt Dynamo...
