A Patent for a Liquid Nitrogen Tank-Fan Air Conditioner

This Perpetual Copyright and Patent by Anthony J. Fejfar and Neothomism, P.C., (PA) and the American Public as a Public Domain Copyright and Patent (2011 C.E.) of a Liquid Nitrogen Tank and Fan, Air Conditioner, is described, below, as follows: You use a high pressure steel tank, with dimensions of approximately 12 inches log and 4 inches in diameter, and fill this tank with nitrogen gas under high pressure, which turns the nitrogen to liquid nitrogen with a temperature of approximately 40 degrees F. below zero. You seal the liquid nitrogen cold tank and place it in a air conditioner box with insulation on three sides, and an insulated slat on one side. You then place a high power fan in a position so that it blows air over the liquid nitrogen freeze tank, and thus blows cold air into the room where it is placed. The electric cost for such an air conditioner should be about $2 per month or less.
