personal air-conditioner

 Portable device to provide multiple velocities of super-cooled air.

A small device that could be plugged in to any standard 110 outlet, that would provide a continuous stream of super-cooled air. This is a cross between a standard air-conditioner and a hair-dryer. The oscillating fan would be a thing of the past, replaced by this multi-directional CoolJet. With certain accessories and/or adaptors it could be used in the car, at the beach, etc. Why wait for mother nature to send a cool breeze, when you can enjoy the sun and start the breeze yourself!

great idea even simpler than yours http://www.coolstuf....com/desaircon.html
works on ice. is a hit success! [pashute, Oct 04 2004, last modified Oct 21 2004]

       Sure. Mount it on a baseball cap. Should look really good.   

       BTW, can it work on a few different voltages? Not everyone on the planet uses 110V / 60Hz, OK?   

       Oh, [linky].

       All the important stuff is 110/60, though. There are some very minor countries using oddball currents like 240/50 and the such.

       Sharper image and Misty mates have personal cooling devices, but these are either based on local cooling (neck only) or misting. Other devices use a bucket of ice-water, but they are appliance sized.   

       I recon the main problem for A/C type personal cooling is that much of the cooling is wasted - therefore the macinery needed to cool at such a high capacity is very large.   

       One solution would be to have a mini vaporization cycle unit blowing cold air into a puffy cold-suit. Of course, you'll end up looking like the Michelin Man.   

       If you want to do it and keep your figure, you may have to use the water-cooling devices that NASA uses. I've seen the refrigerant packs downsized to the size of a notebook.
