RE: [SG,DS] Power Armour Weapon

Water is good because it's cheap and available.  There is higher tech
stuff like liquid sodium and such but they are nasty to deal with and
you can't just pour your canteen in the reservoir to re-fill it.  Once
you move away from that convenience, then you might as well use
mechanical cooling (a la those funky new refrigerators for the car) or
passive cooling.

For instance, in WWI when running low on water for their MG's it was not
unheard of to contribute to the fluid supply by using recycled human
water.	Since there was no active pumps for cooling, you didn't worry
about contaminants (like urea or salt) blocking up the works.
