At some locations it costs $900 to drill a well, and $100 to build a small lined water pond, if crytocureenicy miners had a waterproof coating, like immersable phones, then immersive water cooling from cold groundwater could cool the mining rigs, every farm golf course and dwelling on 1/8 of an acre could do this. The water moving fans provide orders of magnitude more cooling at much lower and longer lasting fan speeds. Interestingly, watering lawns, crops, and orchard trees with warm water could increase orchard yield and lawn vibrancy. Similar ideas like server farms cooled with ocean water already exist. Some apartment complexes and hundred or thousand room rental housing and brief stay lodging companies make their own heated water centrally, these multidwelling companies could use crypto currency mining to generate all their heated water while earning crypto currency profits. If there is 1 rental lodging unit per 400 people at 40-60% occupancy then that is the electricity paid for, and environmentally neutral equivalent of 700,000 crypto currency miners, although you then divide that with 10 to represent two half hour showers, with hot water tanks full of hot water on standby per lodging rental. Similarly, hmo and private sector medical facilities and hospitals, private schools, hot water heaters at any/much of commercial real estate, could quadruple that to anywhere from 20-40,000 watts for each of 10 million water heater applications at just the US, tripling that number to include Europe and Asia hot water uses generates an environmentally cofunctional, no additional electricity required generation of 100-170 - 1000 million dollars of newly mined crypto currency every 24 hours, or 36.5-365 billion dollars per year at 2021ad crypto currency valuations.
It is possible a completely new internet of things appliance, the domestic and commercial hot water heater, with or without tank that mines cryptocurrency can be introduced. The regular people that use these hot water heaters in their dwellings would actually earn money when they took long showers, or wash garments or vehicles or dishes in warm,. The companies that make hot water heaters could seamlessly and without consumer involvement vend new hot water heaters for just $11, with complementary installation and split all the crypto currency earnings via PayPal or direct deposit 49/51 in favor of the person or company with the dwelling. The water heater making company could use modular construction to simply slide in more powerful computers at the existing base of hot water heaters Periodically The person with the dwelling would get their choice of crypto currencies to mine, or multicurrency (2 that are less than 72 hours old, 2 that are 3 years old, two that are 7 years old) basket, for those optimistic that log growth phase would sometimes occur in some baskets. This strongly benefits the computer engineering of more energy efficient computers and memory as each billion domestic and commercial hot water heaters could get a computing and memory upgrade every time computing power doubles, electricity use halves (germanium) or durability under 100% load doubles (such as from same area of chip, but double thickness height of transistors, lasers zone-refining the pn junction at manufacture, isotopically pure semiconductors, As well as plasmonic chips).
Other iot crypto currency miners or cloud computing resources that generate warmth are prewar ming building hvac air wherever people warm dwellings and commercial real estate and prewar ming restaurant food making appliances
