Scalability of a single pod is illustrated. A pod deployment can be implemented for a given power rating or a given water flow or a given power supply current. A server with a power rating of 1.44 MW and a water flow rate of 100 gpm is the repeating element. Power density in the server body (excluding bus bar connections) can be as high as 2kW per cubic inch in some embodiments. Required water flow rates are lower than in previous systems due to high energy efficiency. Note the small volumes required to produce powerful systems. The accompanying power station will be sized according to the power requirements, differing for choices such as a grid substation, solar, wind, nuclear etc.
