Sun Rice

Thanks to our new friend, Alison, we obtained materials to build first solar cooker here. The bill of materials is short:

  • a piece of metal rod
  • a piece of string
  • a mason jar

The construction we selected is one of most elegant and lightweight available (see http://sunnycooker.webs.com/ for details). It took us maybe an hour altogether (in two days, working as a team) to make the prototype. Continue reading Sun Rice

You adapt it to any size of material you have and it retains all proportions and angles, while scaling] and using solely descriptive geometry means. Fantastic! Continue reading CookIt Panel Cooker

Scorching hot

As you may read in the previous report, I did some extravagant work with the Valentine Box solar cooker, spending a lot of bubbles. While the cooker has proven its efficiency, I had some doubts about its durability. So I put it outside and let the sun do the testing.

Patience paid, as we can see below. Neither sprayed foam nor mylar silver foil were able to stand the scorching hot of Greek early spring sun. Even foam blocks melted at the bottom, although sightly. Even the thermometer broke, overheated. Continue reading Valentine Box Mark II
