Stanford cooling tool may improve performance of athletes, soldiers
.... With such devices, you could send a soldier in a chemical
protective overgarment out into the desert, where he would normally have a limited survival time, and he could survive indefinitely with peak cognitive function." The technology is patented and has been licensed by Stanford's Office of Techno...
