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(校园)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 and refrigerators 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 sufficiently heated by people and lights and sometimes must be air – conditioned(使用空调的)even in winter. The technique of saving heat and redistributing(再分配)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, Pittsburgh 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 that female students, and the larger a student is, the more heat he produces. We may conclude that the hottest prospect for the Johnstown campus would be a hard working overweight male genius(天才).

The transition from old fuels to new will be slow, as will the development of new technologies that present feasible alternatives to fossil fuels or help eliminate food and water problems. All current technologies are inadequate, and new ones will probably not be commercially possible by 2025
