Re: In a heating dominated climate
>>"Maybe some clever company needs to create a new line of electric heaters that use their power for bitcoin mining (or cloud computing or whatever) instead of resistance coils. They can advertise "heat that pays for itself"..."
I seem to recall that someone did try and kickstart a similar idea, but it wasn't practical - basically, your initial install costs are so high compared to using traditional radiators or space heaters (and electric heating is so expensive anyway, compared to gas) that it's not a remotely attractive addition to an existing building.
Ahh, but have you seen my kickstarter for a gas powered bitcoin miner/heater? A better investment than my cold-fusion rig was (great mining, crap heating...)
