Possible uses for Heat Generated by btc mining?

[Johnny Bitcoinseed]

I live in the Great North Woods and there is a frost nearly every morning now.  It's heating my house as I write this.

I should factor that in, wood and oil heat cost money.

I remember seeing some post state that you can use heat to covert it back to energy. Just that the technology is not mature enough and won't ROI. Maybe in the future we can.

second law of thermodynamics my friend i believe is what you will be trumped by here every time.  And the loss of energy through inefficiencies and just changing energy states.

I'm heating my house right now. last night it was -1c and I had to turn on my AC!

I put my miners' heat to good use:

Lolz, I am so ganna try this. Putting my bread in-between 2 GPU.

It's very low grade heat. Room heating is about all it is good for.

Well, my GPU can hit 80-90c depending on my overclock and setting. If I have like 7 and I can find a way to direct my heat. It would be lots of heat..

That's still very low grade heat compared to an ambient room temperature of 20C!

90C (very hot for a GPU) is 363K.
20C (room temperature) is 293K.

The maximum theoretical efficiency for this is 1 - (293/363) = 19.2%

So, at BEST, you can get 200W per 1000W.  Realistically, you'll be lucky to get half of that, for a rather major cost.

It'd be really cool to implement a wintertime driveway/road heater powered by waste heat.

Something like,
1. Run a bunch of pipes under the surface of a blacktop or gravel (probably easier) driveway or road
2. Circulate coolant through the pipes and through radiators (with fans) placed in the indoor mining room(s)
3. Coolant would be cooled outside under the road surface, transferring heat to melt snow/ice
4. Coolant would be heated in radiators in the mining rooms, drawing heat from the air and cooling the mining room.
- Optionally install temperature probes on the radiator inlets and outlets and automatically shut the system off if the amount of heat transferred out of the room drops below a certain threshold. (i.e., when it's too warm outside)
- Optionally put water blocks on mining processors and use heat exchangers to more efficiently transfer heat into the driveway coolant loop

Wouldn't be practical for everyone, but most people here in the Northeast US (and everywhere else it snows) hate shoveling snow off their driveway.  The constant heat produced by mining could always keep the driveway warm enough such that snow melts upon contact and never has a chance to accumulate. 

Although my plan this winter is to simply move some mining equipment out of the basement and into my apartment where I can enjoy the free heat.

Best use I found was

tropical fish tank or reptile vivarium

free heat for pets you would otherwise have to waste electricity on to keep warm.

Heating house in winter is not a bad idea, but you will turn off the miners in summer ? Because in summer it cost a lot of electricity to just cool your miners.

What do you mean? I tried warming my tea and it works

[Bitweasil]

That's a use for low grade heat. Not extracting energy with a heat engine.

The heat would be perfect for anaerobic digestion to produce natural gas for cooking/heating .

A usb gets to about 70 degrees centigrade .
I have 11 in a 20 litre bucket of oil ,average temperature 30 degrees .I can add more usb's to get the temperature to the optimum body temperature of 37oC.

Throw poo, wee ,and waste food matter,peeling and such in a 1000 litre container with the drum of oil sealed inside  ,after 3 weeks I have all the free gas I could need for a family of 5,just keep adding crap and mining coins = win .

I personally have produced gas and it felt really good to see a blue flame come out of shite .
I used an immersion heater to experiment but that was before asic heaters were invented lol

[waltermot321]

Best I can think of is use it as a warmer. Maybe toast a bread but would take hours
