Our waterways are becoming more and more polluted due to PFAS, plastics, medicines, drugs, and new chemicals made by companies that just hand over the responsibility of cleaning to plants paid for by public moneys. Detecting the different chemicals and filtering them out if getting harder and harder. Could the simple solution of heating up past a point where even PFAS/forever chemicals decomposes (400C for PFAS, 500C to be more sure about other stuff) be alright?
Lava is 800 to 1200C and regularly comes in contact with water, which turns into vapor in our atmosphere.
It’s not about bringing the boiling point to 500C, but getting the water (vapor at that point) to 500C.
So what I’m hearing is, we need to drill a hole into the earth’s mantle and just start shucking water into it.
