Energy Efficiency - Data Centers



In our current project we deploy a distributed datacenter in peoples homes with 120 Gbps fiber. We connect the water cooling of the CPU and GPU directly into the heating of homes and offices. Power comes from $0,02 per kW solar and wind in the neighbourhood. The waste heat is not wasted, it is sold to the homes and offices. This saves up to 95% in energy at 30% the capex.
