Talked with my brother nostr:npub1ajv7m32k0cpgzha32qszsh304qusjvwwmavus0ttktzldms4xzusuftppj at least 100 times about this, lol.

The major difference in cost is entirely with whether you get the heat from electricity or something much cheaper like gas. But dryers are *always* electrical. Which means miners are the perfect match. The one drawback is upfront cost versus the amount of time they will be idle.

The best value would likely be in a laundromat or something similar where they will have a higher time in operation.

(Also would need one of the pools that pay out per hash, rather than per block found)
