In the United States, one of the leading researchers into heat recycling is Paul Brenner, a computer scientist at Notre Dame University in Indiana. Brenner’s interest in recycling started because the computers were running very slowly. The reason was the cost of cooling them, _____ Brenner decided to look for ways to reduce cooling cost.
Unlike the Finnish system, which used water to heat cool, he used the computers themselves. First he experimented with a small set of computers placed in an office, but connected themselves with the university’s a data center. When the office was cold, work was sent to these computers and the room pon warmed up. When it was warm enough, the computers stopped working.
