Qarnot’s wall-mounted heater doubles as a crypto-mining rig
As a student, I used to joke that my Xbox 360 doubled as the flat's central heating system. A few hours of Red Dead Redemption and boom, I could slip under the covers and fall asleep without an icy-cold mist forming around my breath. Qarnot, however, isn't joking about its new QC-1 "crypto heater." That's right, the startup is promoting its first crypto-mining rig on the inevitable warmth that its innards will produce. Generating Bitcoin and other "digital gold" requires expensive electricity, so why not save some money by heating your home at the same time? That's the pitch, anyway.

But French startup Qarnot has a better idea: Use that energy to heat your home.
