Hot little bodies keep cold schools warm in Siberia
8 July 2061
A local school in Siberia at Yakutsk, a city of 100,000 people, has been built with a heating boiler no bigger than that found in many local homes. Instead, the heat is being supplied by the warmth given off by the three hundred children who attend the school.
During the day, the heat from their bodies is stored in the walls and ceilings and is then released overnight to keep the school warm for the following day, and to keep it at a cosy temperature of 20°C, even when the temperature outside falls to minus 40°C. The secret is a new type of wall insulation which is proving so successful that there are now plans for all future buildings in this part of Russia to be constructed from it.
In the last school where I taught the annual heating bill was in excess of 100,000 new roubles a year (equivalent to $10,000) and still we always felt cold” said one of the teachers, Ivan Ivanovich. “Now we need have the central heating on for the day before school starts, and once the children are in the building it remains cosy all day and is still warm when we come in the following morning.”
