I've made a new area in my website for projects. When I get the time I'll add a lot of past projects, but at the moment I'm most interested in getting this generator built.
Here is my solar thermo-electric generator page:

I'll add more details as I build the thing, and I'll add test results as I get them.
If anybody has any suggestions, I'm all ears.
We'll see how it goes.
