Qarnot (QH-1) - Making buildings smart with free computing waste heat

QH-1 heats buildings by reusing waste-heat from microprocessors performing high performance computations remotely.

Given that data entres consume 3% of the world's electricity, QH-1 takes advantage of this lost heat and uses it as a heat source to warm rooms. Through a disruptive and distributed infrastructure, it provides cloud computing where computing power is no longer deployed in concentrated data centers, but split throughout the city. Buildings become "smart" because of QH-1. It offers free heating, Wi-Fi, an auto-scheduled heating mode, remote control, voice command, air quality monitoring, fire alarm detection, presence and intrusion detection. QH-1 heats social housing units and building offices for free while computing remotely for major banks, 3D animation studios and research labs.
