     No matter what he is doing, every human being gives body heat. The usual problem is how to dispose

of it. But the designers of the Johnstown campus of the university of Pittsburg set themselves the opposite

problem-how to collect body heat. They have designed a collection system which uses not only body heat

but also the heat given off by such objects as light bulbs and refrigerators as well. The system works so

well that no conventional fuel is needed to make the campus's six buildings comfortable.

     Some parts of most modern buildings-theatres and offices as well as classrooms-are more than heated

by people and lights and sometimes must be air-conditioned even in the winter. The technique of saving

and redistributing it is called "heat recovery". A few modern buildings recover heat, but the university's

system is the first to recover heat from some buildings and reuse it in others.

     Along the way, Pitt has learned a great deal about some of its heat producers. The harder a student

studies, the more heat his body gives off. Male students emit more heat than female students, and the larger

a student, the more heat he produces. It is tempting to conclude that the hottest prospect for the Johnstown

campus would be a hard-working, overweight male genius.
