cdgrinci Posted March 7, 2012 Report Share Posted March 7, 2012 A lot of money was spent for this (development/distribution/manufacture), which in my opinion, is of minimal benefit. The article claims some reduction of CO2, but with ICE's spewing CO2 (in tons/year), how can a closed system (A/C, for the most part) do anything to alleviate CO2 levels. A drop in the bucket would be generous (in it's description), maybe a grain of sand on a beach would be a better analogy. The new refrigerant cost (currently) is 70 dollars per pound, is slightly flammable, requires special equipment to install/reclaim and is only being produce (in bulk) in one Chinese factory (currently). Too many 'red flags' for me. Chuck '19 CT6, '04 Bravada........but still lusting for that '69 Z-28 Link to comment Share on other sites More sharing options...
