Controllers have advanced more than any other part of the electric car over the...

Kitchen in the

We've all heard the saying about too many cooks in the kitchen. But what happens when you move your kitchen into the sun You get a myriad of solar cooker designs, great food, and lots of fun in the sun. We found this out recently at Home Power's 2nd Annual Solar Cooking Contest. Last February, we offered a challenge to our readers design and build a simple, cheap, and easy to use solar cooker that works well. The rules were simple the cooker had to cook, meaning it should boil water. The cooker...

The Renewable Energy Education Program (REEP) will be held at Solar Energy International (SEI). One to two week workshops are for owner-builders, people seeking careers as solar professionals, and people who want to do work in developing countries. The hands-on, how-to workshops offered September through November include PV, passive solar, wind, micro-hydro, solar cooking, food drying, and more. For a detailed description of REEP, costs and scholarship information, write SEI, POB 715,...

Handmade Hydro Homestead

In 1975, Matt and Roseanne Olson's diesel generator died. Faced with an expensive repair, Matt figured this was as good a time as any to build the hydroplant which he'd been collecting parts for over the past four years. With the help of his good neighbor and friend, Rod Ward, he set to work building a temporary fix for his generator problems. Eighteen years later, that temporary fix is still producing clean, renewable electricity. The old diesel plant has long since been traded for spare...

The energy economy figures were impressive with only 8.85 kWh of battery and 4.6 gallons of fuel consumed. That's 6.2 miles per kilowatt hour and 34 miles per gallon Assuming 0.08 per kilowatt-hour, a charge efficiency of 85 , and charger efficiency of 90 , the cost of the electricity amounts to 0.92. That means a buck's worth of electricity would...

Roof of our two story apartment building. The unbreakable panels rest on our awning, allowing easy removal to take to the beach, UCS (Union of Concerned Scientists) information tables, or PV demonstrations and speeches as well as for instant snow removal. The panels on the roof are wired for 12 Volts DC necessitating two 50 foot runs of 10 gauge Romex to the batteries. The section running through the window and to our control system is clad in conduit. A piece of scrap Styrofoam was cut to...

Cruising Equipment Co Seattle Wa A

Our new Kilowatt-Hour Meter was created for the Department of Energy to provide instrumentation for one hundred electric vehicles that participated in competitions this summer. The data gathered from the Phoenix 500, the Atlanta Clean Air Gran Prix, the American Tour de Sol, and the Ford HEV Challenge, is the largest sample of energy performance data that has ever been collected. The final report on this data is yet to be published, but the preliminary analysis has established the benchmark of...

The Gridman Cometh

Southern California Edison SCE has proposed a three year, 2000 kiloWatt peak , pilot program to provide photovoltaic PV generated electricity to users in their service territory where line extensions are uneconomical. How will this affect the development of the Renewable Energy market Read on Some of the details of the plan are still sketchy, but as it stands now, a potential off-grid customer will be handed a list of approved contractors. These contractors will pick from a list of standardized...
