Swedes to Use Body Heat to Warm Offices
(01-09) 05:33 PST STOCKHOLM, Sweden (AP) --
A Swedish company plans to harness the body heat generated by
thousands of commuters scrambling to catch their trains at Stockholm's
main railway station and use it for heating a nearby office building.
Real estate firm Jernhusen AB believes the system can provide about 15
percent of the heating needed for a 13-storey building being built
next to the Central Station in the Swedish capital.
"It just came up at a coffee meeting last summer. Somebody suggested:
why not do something with all this heat in the station?" project
leader Karl Sundholm said.
About 250,000 people pass through the station every day, warming the
air inside with their body heat.
Sundholm said the idea is to have large ventilators in the station
suck in the warm air and use it to heat up water, which will then be
shipped through pipes to the new office building.
The system will cost about 300,000 kronor (euro32,000; US$47,000) to
install, he said.
"All that's needed is a few pumps and some pipes," he said, adding the
station is already equipped with most of the required ventilator systems.
