Yup, you read that correctly, the Qarnot QC-1 ($3500) passively mines crypto-currency while it heats your home. If you’ve ever mined crypto yourself you know that video cards and processors create an incredible amount of heat. Qarnot has taken that nuisance and turned it into a feature. The QC-1 works by dispersing the heat two video cards and the processor in the unit into your home. The included app lets you monitor crypto markets, monitor the mining mode of your device, and activate a heating booster and mining level. It also has an option to choose the crypto you want to mine, including Bitcoin & Litecoin. And if you’re into mid-century modern furniture, you’ll love the looks of this heater with its use of wood and fabric.
