The amount of energy they consume doing useless busy work is obscene and has completely negated all the progress we have made toward greater efficiency and lower environmental impact. --- End quote --- While I love crypto (technically and practially) I do TOTALLY agree that amount of energy wasted for Proof of Work crypto projects is enormous. That's why we are NOT ONLY focusing on crypto mining hardware and we are also providing immersion cooling ready 19/21'' servers [warranty included] for AI/ML/Rendering or any other type of HPC projects.

There's one who used to post in this forum (until the TEApocalypse), and she powers her rig using solar PV, and uses the waste heat to help warm her house. Granted, it's a pretty small set-up in the grand scheme of things, but it does show it's possible. |

Or make it something that uses less energy, but that's a harder problem to solve in the long term. --- End quote --- If it uses less power it's not going to be worth as much. If you try to make something that consumes little power, someone will just use bigger hardware that uses more power in order to mine it faster. I don't see any way to make it hard to mine that won't also encourage large amounts of power to be used. The entire concept is fundamentally flawed, and all crypto is useless as currency because it is so unstable. If you can make a lot of money investing in it then it's not a good currency. --- End quote --- I do totally agree with You James. Now imagine, that there is a project where You can share You computional power and get reward in crypto for doing that. It's already there. But in the end transfering that crypto closes the loop and we are at Your point again. As I have already written. I do love crypto technically but I do totally agree that it's wasting computional power for things that does not require that amount of power. Difficulty for confirming Bitcoin transaction is artificially increased. This is, sadly, how it has been designed. As I have already mentioned, several times, that is why we are not focusing with our technology strictly only on crypto but also on other applicatioins. But since crypto is with us and will stay with us and is using enormous amount of electricity it's essential to lower that power usege and RECOVER and REUSE all wasted energy. That's what we are doing. How much heat is generated by computers that are working? FlameIT - Immersion Cooling: Is this true that computers convert all electrical energy into heat? TL;DR: With fans removed and all equimpent immersed You can safely assume that that with 1kW of electrical power going into computer You are getting 1kW of heat Heat reuse example: We are heating hotel swimming pool This setup is capable of delivering, constantly 20kW (pumps and heat exchangers were calculated for this amount of heat). With 20kW of heating power You can for example heat 2000L from 10oC -> 60oC in 6 hours. Now keep in mind that 20kW heat source is constantly on. That's why 3kW of heating, constantly turned on is capable of heating 140m2 house to 21oC when there is 1oc outside. |

You can read about my first, proof of conept installation (still working) we have built back in 2018. https://flameit.io/assets/pdf/articles/onet-noizz-mines-cryptocurrency-and-heats-house.pdf Now, my PV installation got a bit bigger. As I have already mentioned, I love to experiment but on myself first ;) We can experiment WITH customers and we are doing that, of course, with their full awareness of what we are doing and what we are testing.

One could also use something other than energy as the limiting factor. There were quite a few smartphone mined coins back in the day which were limited by IP address, with VPN/VPS ranges blacklisted. Most of those failed by greedy exchange operators crashing them. The closed ecosystem they are based on also moderate the value of the coins produced, but introduced many other problems. In principle, there could be a cryptocurrency mined by seeding content. Basically providing an incentive to create a decentralized alternative to Youtube. But nobody has figured out how to make it work yet. |
