Good stuff. Another good source of heat that can be converted into yada yada is geothermal power and there are commerical companies already doing this. The greatest challenge we face is the stranglehold big corporations have on maintaining the status quo. They’ve invested trillions of bucks in the dead and dying heat transfer paradigm. That is the number one problem we have with climate. The solutions are already known but there’s great resistance and it spills out from the fossil fuel industry to politics. Vladimir Putin is ultimately acting to protect the fossil fuel paradigm for instance. See Rachel MAddow’s “Blowout” or my own “The Age of Sustainability.”
