Title: SOLAR COMPETITION

OK, here's the competition:

Most innovative use of Navitron solar vacuum tubes for cooking food or drink.


Please post your experiments, however successful or otherwise. Prize will be a pound of Asda Premier Sausages, unless I can come up with a better prize in the meantime (hopefully!)

Hmm..........  >:(

I hope you are accepting retrospective applications  :)

I seem to have failed on the Solar shower piccy competition - despite being the first one to post in that one.

We had the idea in the office of using a demo tube to heat soldiers rations in Iraq or Afganistan. They would simply place the rations in the tube with some water in the morning attach it to their packs and after a few hours in the desert it would be ready to eat.
One big problem with the idea is the "battle friendliness" of the glass tubes. We didn't think they would like being shot at.

How about a slow cooker? A well insulated box constructed around the business end of the tube. Stick a heatsink (preferably made from diamonds  :P) over the rod end. Bung your casserole or whatever your cooking in the box and place in the sun for 8 hours or so...... Move over Jamie Oliver.

Just Googled it and it might have been done. No pics but lots of geeky talk about it.

the proof is in the pudding  - quite literally.

I think between us we have already made far more progress than anyone else (in the world) - a few simple experiments is worth far more than conjecture. Therefore...... we want to see the pictures!

Geoff is quite definitely in a different league at the moment (yes, of course retrospective entries count) - lets see some challenges!

Mike - unless the office is in Afghanistan surely there will be a problem with the length of the tube and the curvature of the earth ! :D
