This is a “videmail” communication from Solar Cities founder TH Culhane in Germany to field coordinators Hana Fathy of the Christian Zabaleen community and Mahmoud Dardir of the Moslem Darb El Ahmar community answering questions on how to adjust the panel angle and the cold water pipe in the hot water barrel to make the do-it-yourself solar hot water systems we build there function properly. To transcend cultural and language barriers, as well as time and space, we use Google Sketchup …

In the future, all of our energy will come from renewable sources. With traditional gas and energy costs skyrocketing, it is apparent that we need to find new ways to make energy production which are sustainable. We need to change our thought process about how we use the Earth and begin to convert our old energy grid into something sustainable.
There are some people who have already started thinking this way. New scientific breakthroughs in renewable energy are allowing us to create sustainable energy at lower and lower costs.
Using the right set of plans even homeowners who don’t know anything about construction or electricity can build their own alternative energy sources right in their backyards, such as wind power generators.
Homemade wind turbines can currently generate enough power to reduce the average household’s monthly energy bill by as much as 70% per windmill. With inexpensive plans they can also be built for as little as $200 using some recycled parts.
They can also be built with materials from a local hardware store and basic tools. An easy way to estimate how much power your wind generator can create:
Power(Watts) = (Wind Speed)^3 * (Blade Diameter)^2 * 0.00478
The speed of the wind makes the most difference because its value is cubed, then the blade diameter because its value is squared. Example calculation using a decent wind speed of 10mph and an 8 ft blade diameter:
W = (10*10*10) * (8*8) * 0.00478 = 305 watts/hour – x 24 hours and you can calculate 7.3 kWh generated per day by a wind power generator.
An average home uses about 12-20 kWh/day. Of course if you conserve your power you can reduce that to much less – even down to 5 kWh per day. So if you don’t have a great average wind speed in your area, a wind power generator can significantly reduce your power bill, and it may only cost you $200.
