This is the first time I have seen something like this. Take a look at this
PORTABLE Air Conditioner. Rolls around on wheels and can be set up like a
simple fan as long as there is 110 volts and someplace handy to hold the
water and exhaust the heat. Incredibly overpriced but shows how small these
things are getting.
