There are some situations where mining Bitcoin is a very good application of energy that will otherwise be wasted. Here are two that come to mind: 1. Flared gas from oil wells. Natural gas is a byproduct of extracting oil from the Earth. In the past this was vented straight to the atmosphere, which is a huge waste of energy and causes horrible air pollution. Capturing this gas isn’t useful for many applications becau…
I don’t mean to direct this at you individually (the sentiment is throughout these threads) - I can’t help but despair when a community of engineers lack the ability to come up with creative solutions for using surplus energy. There is always a better use of those energy sources than Bitcoin mining. Some ideas: Extracting co2 from air, electrolysis, desalination, etc.
Nobody is desalinating their own water at home using waste heat. Oil wells are often located in an area where it would make no sense to transport a bunch of water to desalinate (perhaps that's a good idea for sea-based wells though).
I don't know enough about co2 extraction or electrolysis, only that those also don't sound like things people are likely to do at home.
