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.

I felt encouraged by his words and began to swim more calmly.But my clothes stuck to me like a heavy weight.I could hardly stay above the surface.
Counsel saw this.“Shall I cut them?”he asked.
With a knife he cut my clothes from top to bottom and took them of quickly while I swam for both of us.
Then I did the same for Counsel,and we continued to swim near each other.
But we were in serious trouble.The crew(船员)might not have noticed our disappearance.
And if they had,they could not return because the rudder(舵)had broken.Counsel thought of all this,and calmly made his plans.We decided to wait for the ship as long as possible,because we had no other hope of safety.I suggested that we save our strength so that both of us would not be tired out at the same time.This was how we did it:While one of us lay on his back,quite still,with arms crossed and legs stretched out(伸直),the other would swim and push him along.We changed every ten minutes or so.In this way we could swim for hours,perhaps till daylight.The crash(破裂声)of the ship and the whale(鲸)had appeared at about eleven o’clock.We had about eight hours to swim before daylight.This seemed possible,if the sea remained calm.
