Heating Homes With Bitcoin

Bitroots

“If you're using electric heat where you live, then your computer's heat isn't a waste.” — Satoshi Nakamoto, 2010

The race to develop Bitcoin-powered home heating systems is hotting up, with several stylish devices now on offer. Bitcoin mining generates heat as a byproduct of computation. Rather than venting it outside, a new wave of startups is turning that heat into a feature, producing certified home heating devices that mine Bitcoin while warming your home.
