we do. they are about the size of a solar panel, look similar and are on some roofs of houses in my area. the ones i'm refering to are not for boiling water, just for preheating so need less energy when it goes back into the [ger: heizungskreislauf]. all the ones i know are older then the current PV panel boom. fun fact, there are even concepts (and implentation, but i can't find it) for vacuum glas tubes that have a parabolic mirror around a black painted copper pipe, which should be able to generate ~400 °C "process heat". but they are not wide spread, cause PV is so much cheaper now

AFAIR you can't get new coal/oil because in the meantime there are fungi in the ground that would process the dead plants/alge/whatever was pressed to make the hydrocarbons. but i can't find the source of that info, so grain of salt
turns out we sort of have that. only it does not boil water, but heats the air so liquid hydrocarbons come out of it https://www.research-collection.ethz.ch/server/api/core/bitstreams/186f37f3-be00-415e-8bbb-439b66ee2b75/content
