Despite what recent charts might show, there are many who believe cryptocurrency is the wave of the future. If you want to hop on board that wave and stay warm during the tail end of winter, the Qarnot QC-1 is the heater for you. If you were unaware, mining cryptocurrency requires quite a bit of computing power. How much? Well, Iceland might not have enough electricity soon, so there’s that. Using that idea to their advantage, Qarnot created this space heater that uses a pair of cards to mine at up to 60 MH/s and heat your pad in the process, making heating, as they describe it, “a source of revenue, not an expense.” It connects with an app so you can control the heat and so you can keep tabs on all the magic internet money you’re making in the process.
