accustic heat pump
I just came across some brief information on an acoustic resonating heat pump that uses no oil/cfc but sound wave pressure differential to operate the heat pump. How amazing!!! They had some small working models operating household refrigerators. Of course it still uses electricity however it is more effecient (no gas/oil to heat/cool after each cycle) and is a much greener option. Has anyone had any experiece with such a system or know more details?
thanks,
