[QUOTE=JanGeo;88465]Actually some company just developed a gas turbine electric power system that raised the efficiency to over 60 % don't remember the exact numbers but they recirculated the hot gasses withing the turbine and end up venting only 300 degree exhaust and when used to provide heating raised the total efficiency to over 90%.
I don't think this is the one your referring too.
http://pesn.com/2005/04/25/6900086_J...ortex_Turbine/ This set up needs a platinum coated turbine. Enhanced inlet/out vortex generation. A thermocouple outer shell wasted heat to electricity for HHO generator. A condensator to feed the HHO generator.(they had those on some WW2 planes you know....minus the HHO.) It all can be done without bulky heat exchangers. The exhaust temps would be like a high eff furnace 70 to 100F.
