Sweden to Harness Body Heat of Commuters
It was only last year that I began to fully appreciate the concept of incidental heat gains within buildings - heat gained indirectly via a window facing the sun, the heat generated from electrical appliances and rather surprisingly, the heat generated from our own bodies.
I thought the latter would be insignificant. Not a bit of it.
In fact, whilst sitting down, we provide the same amount of heat as a 60 watt light bulb. This can increase to 250 watts depending on the type of exercise we are doing.
