Water and steam just too goddamn convenient. Super high latent heat so it can move a ton of energy with a quick phase change, works at reasonable pressures and temperatures, stays liquid all the time when you want it to so pumps work, and it’s so readily available as to be damn near free. Super cool!
also almost non-corrosive, non-toxic, doesn’t damage ozone layer, zero global warming potential, non-flammable etc (lots of organic rankine cycle fluids fail one or more of these. tradeoff is utilization of lower temperature sources)
zero global warming potential
This one isn’t right. Nobody will complain about you releasing it, but it’s a quite strong global warming gas.
I like piezoelectrics and kinetic generators. The only two methods of generating electricity I know of that don’t involve steam other than solar panels.
At least, I think they’re different… Is a standard copper wire+magnet generator pizeoelectric? Or is it simply the operation is similar in that you generate electricity from moving things together? Like the difference between tiny little things in your shirt that generate electricity as you move around vs those flash lights you shake to charge.
