Ultra efficient turbo-compression cooling

A method of turbo-compression cooling, the method comprising:

• receiving, from a power generation system, heat waste in a waste heat exchanger;
• heating a first working fluid using the heat waste in the waste heat exchanger to a superheated vapor;
• generating mechanical power through expansion of the first working fluid to a lower pressure in a turbine, the expansion of the first working fluid rotating one or more turbine vanes;
• condensing the first working fluid to a subcooled liquid in a condenser;
• pressurizing the subcooled liquid through a mechanical pump to re-enter the waste heat exchanger;
• transferring the generated mechanical power to a compressor, the compressor configured to receive a second working fluid;
• compressing the second working fluid thereby increasing the pressure of the second working fluid;
• cooling the second working fluid in a cooler;
• expanding the second working fluid to a lower pressure in an expansion valve;
• rejecting heat through a liquid coupled evaporator from circulating cooling fluid to the second working fluid,
• wherein the turbine and compressor are magnetically coupled one to the other and hermetically sealed one from the other, thereby coupling and sealing the power cycle and the cooling cycle, and the first working fluid and the second working fluid are optimized such that the turbine and compressor rotate at the same rotational speed and the turbine and the compressor have an isentropic efficiency greater than eighty (80) percent (%).
