The US energy secretary says the quiet part out loud: the tributary $750 billion in energy purchases the EU has promised in its Trump deal is meant to lock Europe into “long-term” energy dependence.

    Long-term the alternative should be running turbines off of mediums with lower boiling temperatures close to Natural temperature differences we can find to boil and cool a medium with very little extra energy. But we can’t do that because of oil.

      Wait, this is an idea I’ve not heard before.

      The idea would be that turbine efficiency would increase because the alternative evaporating compound, traditionally water/steam, has a lower boiling point?

      Or is the idea that the lower boiling point allows for ecologically preferrable heat sources?

        Yeah for instance there are ammonia boilers that boil ammonia at 80° f and cool it at 60° and take advantage of natural temperature variations to do it. With the right medium you could use this in anywhere from Antarctica to Death Valley. With the right engineering.
