Does anybody have any real scientific insight into the idea that PoW based Cryptocurrencies can harness energy from far away places that is already being wasted? We currently need to send most of traditional energy to our households, cars, manufacturing facilities etc. This cost of transportation to me is the key difference. PoW doesn't need this. Imagine putting some mining rigs in orbit near the sun and harnessing the already abundant solar energy. All you need to send back to earth is a few bytes. I know this is an utopian future but overall the idea of a people's currency is quite important for society, not just for speculation. Most of us I assume are tech people living privileged lives developing software for super rich companies in places with stable currencies and governments. We should realize this is not the case for many people - especially in societies where people cannot trust their countries' government or currency.
