solar powered hotdog cooker?
it can her passive of active, but what will heat a hotdog up the fastest? i was thinking if i didn't want to use solar pannels to cut a box into a curve and line it with tin foil and do it that way but i want to know what will be the fastest
well.. it depends. if you do it with electric solar panels (sized acordingly) you could power an electrical heater instantly (as long as you have enough sunlight of course)
on the other hand, electric solar panels are an expensive technology, a lot to expensive for your hot dog
the easy way to do it would be a thermal collector (like an aluminium plate with water tubing atached). the sunlight heats the plate, the plate heats the water from the tubing and the hot water boils you hot dog. easy, cheap but it might take some time till the water will reach the temperature
