These are just like warm clothes in winter, but just opposite. e.g. keep these specially made shirt and pants in refrigerator; These clothes will absorb and then store the coolth for long time. (may be 2-3 hrs);
After cooling these clothes in fridge, for may be 10-30 mins, they are ready to wear for 2-3 hrs, after which we can repeat the process.
This will be more energy efficient compared to using AC for cooling entire house.
These clothes may be padded with compact, lightweight material ( passive), or padded with thermocouples, in the active version.-- VJW, Mar 18 2011 Like this? http://www.mscooling.com/koolmax [mouseposture, Jul 03 2011] I'm not sure the thermodynamics is right... 30min cooling (in a fridge at 4°C) versus 2-3hrs wearing. It seems unfeasibly assymetric if you ask me, but then people said much the same about Uncle Beff's beard and yet it worked.-- MaxwellBuchanan, Mar 18 2011 Agreed. In that case one will have to keep clothes in the refregerator, for 2-3 ours. If one keeps a pair of these, than this can be managed.-- VJW, Mar 18 2011 [marked-for-deletion] no idea. Needs more language than "specially made shirts and pants".-- daseva, Mar 18 2011 If the people get in the fridge as well, they can stay cool indefinitely.
[+] cool idea.-- pashute, Jul 03 2011 random, halfbakery
