Self-contained power and cooling domains

A method for providing for conditioning of a computer data center, the method comprising:

• supplying a working fluid from a common fluid plane to a plurality of power/cooling units distributed across a data center facility in proximity to electronic equipment that is distributed across the data center facility, at least one of the power/cooling units comprising an electric generator unit configured to generate electric power from the working fluid and output waste from the working fluid to a cooling unit to generate a cooling fluid from the waste to cool the electronic equipment, and at least one of the power/cooling units further comprise a unitary housing that encloses the electric generator unit and the cooling unit;
• converting the working fluid into electric power and cooling capacity at each of the plurality of power/cooling units;
• and
