Read a great story in Parade Magazine over the weekend: http://www.parade.com/health/2009/03/solar-cooker-project.html.  This is such a great project on so many levels:

• It provides critically needed help in a desparate part of the world.
• It is strikingly simple and inexpensive
• It saves lives, both directly and indirectly
• It is a solution that is very earth friendly.

So by all means, after you have read this great story, go to http://www.jewishworldwatch.org/refugeerelief/solarcookerproject.html, read a bit more and definitely contribute – I have.

It will be interesting to see if this concept is adapted to de-salinization.  What a great way to get clean fresh water!
