A recent video piece on YouTube talks with Bernie Karl of Chena Hot Springs in Alaska. Always a character, but one can hardly be more passionate than him describing what geothermal offers him and his business in the state of Alaska.
Using water of around 80 centigrades, he produces geothermal power at around 5 US cents per kW/ hour. Using diesel that would cost him 30 US cents per kW/ hour. Having not only a hot spring pool, greenhouses but also an “ice structure”, he is fore sure inventive.
