ideas for portable cooking
i am participating in a competition <portable cooking>. i need to built up a model without using any battry or generator in order to rise the temperature of water which is placed under the sun. therefore, i need some ideas to built the model so that the temperature of the water will experience a great rise in a short period...

Can you use chemicals? Or is it PURELY just solar-powered?

How about a fire. I find nothing heats something up quite like a fire

Re: ideas for portable cooking
trishelen mentions that it must be "under the sun", which I interpret to mean "solar powered". If that is what trishelen means, then I think that solar concentration is the way to go. Hence, I referenced a *very* detailed thread regarding this, in post #3.

It is possible, with solar concentration, that one could start a fire and also heat the water directly from above. This would raise the temperature *very* fast!

You're no doubt right and I agree. Either a mirror or lens would be the way to go - whichever is readily available. I also would agree the charcoal via solar parabolic thread (which I found fascinating) would be a good resource.

Good luck trishelen
