Not the Onion: Some Americans Trying to Heat Homes with Bitcoin Mining

Bitcoin mining generates heat which is unwanted and wasted in data centers so...

The NYTimes reviewed one of devices:

This Space Heater Mines Bitcoin While Keeping You Warm. (But Not Enough to Pay for Itself).

...Others use the heat from their own in-home cryptocurrency mining to spread warmth throughout their house. "I've seen bitcoin rigs running quietly in attics, with the heat they generate rerouted through the home's ventilation system to offset heating costs. It's a clever use of what would otherwise be wasted energy," said Jill Ford, CEO of Bitford Digital, a sustainable bitcoin mining company based in Dallas... "Same price as heating the house, but the perk is that you are mining bitcoin," Ford said...

At TC Car, Truck and RV Wash, Peterson says, the owner was spending $25 a day to heat his wash bays to melt snow and warm up the water. "Traditional heaters would consume energy with no returns. They installed bitcoin miners and it produces more money in bitcoin than it costs to run," Peterson said. Meanwhile, an industrial concrete company is offsetting its $1,000 a month bill to heat its 2,500-gallon water tank by heating it with bitcoin. Peterson has heated his own home for two-and-a-half years using bitcoin mining equipment and believes that heat will power almost everything in the future. "You will go to Home Depot in a few years and buy a water heater with a data port on it and your water will be heated with bitcoin," Peterson said.

Experts like Derek Mohr point out that "home computers, would have almost zero chance of being helpful in mining a block of bitcoin."

I think Hasbro should bring back the Easy-Bake Oven as "The Easy-Bitcoin Oven"

At least there is some concern about the reuse of of the heat-pollution of the bitcoin mining.

I'd rather the idiocy at least reduce home heating.

in greenhouses, a throw back to the green roof craze of the 2010s. Greens and tomatoes are especially well suited to rooftops because they are quick cycle and relatively high value crops. Some supermarket chains played with putting them on top of some urban food stores -- literally "vertical integration".

The typical house has a 150,000 BTU per hour furnace.
That's around 158 million joules per hour.
That's 43,888 joules per second.
A home data mining operation provides over 43,000 watts of waste heat each second?
The typical home only uses 35-40 kilowatts per day.
That's one heck of a "home" computer".

75-cents worth of electricity netted less than 15-cents worth of bitcoin. Also that the appliance was only suitable for space heating.

150K seems quite high for most homes, even in Zone 5 -- "50 to 60 BTUs per sq foot" x 1600SF = 80,000 to 96,000 BTU

We have a circulating hot water system that's 125k BTU, and we don't have a big house. Just average size.
I know that's right because it's stamped right on the spec plate on the front.
And it was sized by a guy we knew to be expert in this stuff.
It's possible that they size water systems higher because the high heat capacity of the water stores that energy do well.
Not sure

and it said it was a great idea.

Said that heating homes with AI would be even better! A "bubble" yes but a warm bubble.
