Same applies to geothermal.

lava is really hot use lava to boil water use steam to turn a generator free electricity!

Have we still not been able to progress past all power generation being “use water to turn a generator”? Humanity figured out the water wheel then just kept making it more complex.

How about “use air to turn a generator”? Now that’s original. Or photovoltaics, I guess.

So I’ve tried starting a perpetual windmill and it made money on only fans but it turned out the be an electrical loss overall… Had to abandon that attempt, back to the drawling board, I think I messed up somewhere.
