The amount of power required to compress a refrigerant to sufficiently
cool the air precludes any thing smaller than a good sized backpack.
And I would like to point out an error. The A/C process is the closest
thing you can get to a purely thermodynamic process. It's not a
mechanical process any more than the generation of sparks of static
electricity generated from a condenser charged with a Van De Graf
generator.

> 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.

So long and thanks for all the fish.
