The newest AI boom pitch: Host a mini data center at your home

Qarnot's residential mini data center delivers free hot water while earning you up to $300 monthly from server heat reuse. Each QBx unit runs at 1.5 kW thermal output, outperforming Amazon devices chief says a new smartphone is “just not the goal”'s typical electric water heater in energy efficiency. According to Qarnot, the system offsets about 2 tons of CO2 annually, which is 40% better than standard data center waste heat solutions. Homeowners considering this must weigh a $4,500 upfront cost against potential savings—a calculation faster than the average home energy upgrade ROI.
