5. Compound parabolic solar cooker

The object is to get the power of a parabolic solar cooker but without the need for perfection.  A compound parabolic dish does not need to be made perfectly and does not need to be perfectly pointed at the sun either.

Mine reliably gave about 2 hours of cooking without the need to repoint it at the sun. (Parabolics need to be repointed every 20 minutes or half an hour.)

This solar cooker can be made with a mud dome as a mold or as a mud or cob dish with tinfoil stuck on or from "petal" templates that are stuck together to make the dish. I made one in September 2008 and it gave good results.

I did the math for the compound parabola and rays of light in 2 dimensions.  But a dish is a 3 dimensional thing. Hopefully things are fairly correct. More up to date details on instructables dot  com under gaiatechnician user name. I intend to model the rays in 3 d on a small cob model with a laser level.

Others might be able to do it with pov ray, blender or cad software. I do not know how to use them. Brian White

6. The environmental fact book

7. GLI Thunderbird 10 KW kite based wind power system

8. GLI Firefox solar stirling engine

The choice of the names Thunderbird and Firefox is our tribute to the open source software community, not only to the people involved making Mozilla Thunderbird and Mozilla Firefox, but to all people involved in the community driven social production of software that is the Open Source movement.
