Glasgow venue SWG3 has introduced its new power system, which creates renewable energy from the body heat on the dancefloor.
The heat from dancers is piped via a carrier fluid to 200m boreholes that are charged like a thermal battery. The energy then travels back to the heat pumps, is upgraded to a suitable temperature and then travels back into SWG3.
The owners say the new system, called Bodyheat, will allow them to disconnect the venue's gas boilers, and reduce its carbon emissions by about 70 tonnes of CO2 every year.
