> Also, heating is a simple problem. Many things contain chemical energy that can be released. Cooling, on the other hand, requires you to defy natural law by convoluting the process. Your task is to take heat from a lower heat area and move it to a higher heat area. As mentioned in this guys post, this is accomplished by using a chemical that evaporates easily, letting it absorb the heat to evaporate, push it elsewhere and force it to condense, releasing the heat into the higher heat area by mechanical rather than thermodynamic process. This ingenuity has always amazed me far more than microchips and the various memory technologies we deal with.

No idea how well it'd work but I was playing with the idea of trying to 
build (or maybe buy? nah..) a really small compressor that could be 
build into a belt buckle and would run off a small battery (also 
included in the buckle.. and also the avaporation valve). Then I wanted 
to build a multi layer belt that had an inner layer of tubes that 
supplied the cooling and then, sepperated by insulation, a layer of hot 
tubes covered by something like a heat sink. I wanted to make something 
of a special shirt that'd reflect out the heat and keep the cool air in 
and have a lil fan that'd blow air from the cool side of the belt up 
through the shirt. I figure the area inside the average persons shirt 
not filled by their body wouldn't be a lot so you don't need to really 
move to much heat so it might work if you could manage to make the 
compressor and such small enough and find the right materials for making 
the belt itself.
