Reverse brayton cycle with bladeless turbo compressor for automotive environmental cooling

A method for cooling an automotive cabin, comprising:

• receiving engine combustion gases in a first turbine of a bladeless turbocompressor to drive a first bladeless impeller coupled to a second bladeless impeller of a compressor;
• receiving and compressing air in the compressor by the second bladeless impeller;
• receiving and cooling the compressed air from the compressor with an intercooler;
• and
• receiving and expanding the cooled, compressed air from the intercooler in a second turbine, the second turbine having a third bladeless impeller driven by the cooled, compressed air, the cooled, compressed air expanding and becoming further cooled thereby.

An apparatus for cooling an automotive cabin, comprising:

• a first turbine means for driving a first bladeless impeller from received engine combustion gases, the first bladeless impeller coupled to a second bladeless impeller of a compressor means for compressing receiving air by the second bladeless impeller;
• an intercooler means for cooling the compressed air from the compressor;
• and
• a second turbine means for expanding the received the cooled, compressed air from the intercooler, the second turbine means having a third bladeless impeller driven by the cooled, compressed air, the cooled, compressed air expanding and becoming further cooled thereby.
