minus-squarePup Biru@aussie.zonelinkfedilinkEnglisharrow-up0·20 days agogeothermal typically uses chemicals other than water because they have a lower boiling point the specific chemical being cheap is relatively unimportant if it’s a closed loop. the cost is next to nothing compared to the whole construction

minus-squarenot_IO@lemmy.blahaj.zonelinkfedilinkEnglisharrow-up0·19 days agoshouldn’t it boil so that it can expands and makes pressure to move a turbine? why use energy to make a counter pressure

This kills the crab
well the Chinese already use co2 turbines irl so idk what you’re going on about
shouldn’t it boil so that it can expands and makes pressure to move a turbine?
