【题干】Passag3
Every human being, no matter what he is doing, gives off body heat. The usual problem is how to get rid of it. But the
designers of the Johnstown campus of the University of Pittsburgh set themselves the opposite problem – how to collect body
heat. They have designed a collection system which uses not only body heat, but the heat given off by such objects as light
bulbs 电灯 and refrigerators 冰箱 as well. The system works so well that no fuel is needed to make the campus's six buildings
comfortable.
Some parts of most modern buildings – theaters and offices as well as classrooms – are more than sufficiently heated by
people and lights and sometimes must be air-conditioned even in winter . The technique of saving heat 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
buildings and reuse it in others.
Along the way, Pitt has learned a great deal about some of its producers. The harder a student studies, the more heat his
body gives off. Male students send out more heat than female students, and the larger a student is, 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.
