Every human being,  36  what he is doing, gives off body heat. The usual problem is  37  dispose of it. But the designers of the Johnstown campus of the University of Pittsburgh set themselves the  38  problem — how to collect body heat. They have designed a collection system which utilizes  39  body heat, but the heat given off by such objects  40  light bulbs and refrigerators as well. The system works so well  41  no conventional fuel is needed  42  the campus’ six buildings comfortable.

A few modern buildings recover  47  , but the university’s system is the first to recover heat  48  some buildings and re-use it in  49  . Along the way, Pitt has learned a great deal about some of its heat producers. The  50 a student studies, the more heat his body  51  . Male students emit more heat than 52  students, and the larger a student, the more heat he  53  .
