This is just a geothermal unit with the evaporator built around the load and instead of air to air transfer through convection it is air to air transfer through radiation... nothing but smoke and mirrors. The problem with efficiency and A/C is the excess heat generated by the compression element of the Refrigeration Cycle. The closest thing to 100% efficiency is achieved through absorption chillers that utilize an internal chemical reaction based off of external heat to produce compression through a metered system... neat idea though. Heating systems that utilize the same process are different though - you can achieve greater than 100% efficiency with the use of flash gas bypass designs that will say for example produce 1.5 tons of heat in a 1 ton system.
