Saw an interesting item on the local 6 pm news tonight.
A Cape Breton guy was demonstrating a heating system he constructed.
It was based on a 'heat pump' principle, but instead of the water pipes
being buried in the ground to extract warmth, he ran them through a 'magic
box' that somehow brought the water from room temperature to 134 deg F.
He wouldn't say what his magic box contained... but it was only the size of
a large tool box.
He says a number of manufacturers are calling him for info, but he'd like to
see the product constructed in him area to provide employment for the
locals.
According to him...this thing could heat your house for the price of
electricity to drive the pump.
