Amid all the heat around cryptocurrency, one of the criticisms lobbied against the futuristic economy is the heat around cryptocurrency — that is, the massive amounts of energy that it takes to mine the currency and create blockchains. While French computing company Qarnot hasn't solved the energy issue per se, it's found a way to make the most of the situation with its newest product, the Qarnot QC-1.
Hard-working computers generate a lot of heat, as anyone with an old laptop has felt for themselves. And if laptops make one's thighs uncomfortable, imagine the temperature of a high-powered computer working non-stop. The Qarnot QC-1 does just that, operating around the clock to mine cryptocurrency. What's ingenious is that, rather than serving as a regular computer, the QC-1 also channels its heat outward, serving as a heater for consumer homes. The computer effectively earns the cryptocurrency of consumers' choice while performing a service that they'd need in their homes anyway.
