I hope he uses a large air filter before GPUs.
even pollen filters since I'm allergic to everything outside

Re: I heat my home by mining crypto currencies
#82I wonder if we could make it even better and make smart heaters that instead of wasting calculations actually do something useful, something like folding proteins or some other computing load that doesn't require huge network load and can be easily distributed (something like SETI@home but actually useful). In densely populated cities we could bury huge datacenters underground and use that energy for heating directly…
SETI coin should be a thing. It’s nice for people to fold without prompting or compensation, but the added incentive would most likely draw a significantly larger market.

#83What will happen to the cards once the crypto boom is over? There was a lot of trashed AntMiners out there after the late 2017 bubble, and with it a good amount of CAPEX written down.
they still make great LAN party GPUs. HL2 mp is not a problem and even ark runs on them somewhat

Welcome to Qarnot. https://qarnot.com/en/the-radiator-computer/
> The computing-heater warms buildings ecologically and for free, thanks to the waste heat released by embedded microprocessors. By performing complex IT operations... ... which are what, exactly?
looking through their tech stack and the hello world example and stuff I think you can put your own stuff i n it, but probably the most common stuff is 3d rendering.
on edit: I got a downvote so someone must think I'm wrong? the basis of my idea was - in the FAQ
https://computing.qarnot.com/en/FAQ
3D:
Blender, Maya, V-Ray, Guerilla
IA / ML / Big data or simulation:
Code Saturne FreeFem OpenFOAM PyTorch TensorFlow SickitLearn Spark
If there is a Docker image, we support the software! You can either bring your own or choose an existing one on Docker Hub. You can also ask our experts for help!
I expected the 3D stuff put up top made it the most used, but could be wrong in that. Obviously also some data crunching, ML tasks, but at any rate if my answer was wrong and so off base as to get a downvote maybe you could also just say why I'm wrong and what it's generally used for?
on second edit: developer documentation https://computing.qarnot.com/en/developers/overview/qarnot-c... made me think that maybe if you have one you can get your own api token and put your stuff on it, obviously you would have to pay them for that so not sure how it would work.
Re: I heat my home by mining crypto currencies
#85I'm not sure I understand the principle. A heat pump achieves a COP (coefficient of performance) of approx. 3-4 (e.g. by investing 1 kWh of electricity, a heat pump generates 3-4 kWh of heat by extracting from the surroundings, air or sole, 2-3 kWh). In this example, by pre-heating the air, you supply the heat pump with ~0.9 kWh of thermal energy (the miner will convert 900 watt directly to heat I would assume). So i…
On principle, yes. There are quirks - the COP is different for lower temperatures, and becomes 1:1 at around 5F (-15C). So preheating the air could improve the effectiveness at low temperatures, and I am guessing it might look like this:
- before: 1kWh in, 1kWh out - after: 1.9kWh in, > 1.9kWh out
However, if it was that simple, I suppose heat pump manufactures would include a pre-heating as built-in feature.
It's very likely that he reduced the energy consumption of heat pump by 50%, but at the same time he uses more than those 50% for mining and has a negative total result that is being offset by the profit from mining itself. Which probably nice for him, but not really for environment :)

'Proof of Useful Work', as opposed to proof of work, is a thing! https://eprint.iacr.org/2017/203.pdf
Any coins / tokens that implement this or something similar?
The proof of work in tokens has to be a net waste of energy; the idea is that the proof of work is costly enough to prevent a 51% attack.
Making the proof of work do “useful” things would lower the cost of said work thus lowering the barrier of entry to an attack.

Currently a Facebook datacenter in Denmark is supplying around 10.000 homes with heating.
You can argue that Facebook isn't actually doing anything useful, but still, it's better than to waste the generated heat.
Re: I heat my home by mining crypto currencies
#88Years ago when mining with a single gaming card was more common and viable, I lived in a rented room in a house owned by a live-in landlord who controlled the heating, and wouldn't turn it on for very long in the winter. Since electricity was included in my (fixed) rent, I was able to keep my room a few degrees higher than the rest of the house. However I must point out that you shouldn't do this in most circumstance…
In countries like France [1], electricity heating is the most environmentally friendly, at 40 g Co2/kWh, while gas (the cheapest and most common) is >250.

#89My mining rig will stay profitable until the ETH price is at ~900$
I don't think this is at all true. Even if the price of the crypto remained stable, the mining difficulty will keep on increasing as more miners join. So after a time, his mining rigs will consume more money in electricity than they generate in coins.

Produce electricity? I assume electricity was used to do the computation in the first place, turning into let's say 80% work and 20% heat. The idea was to use that 20% to heat our homes. The original electricity still needs to come from elsewhere.
Doing computations hardly stores any energy anywhere (the energy stored in, say, magnetization in a magnetic disk is pretty much negligible), so almost 100% of electricity is turned into heat. The problem with this ~100% efficiency is that, if your goal is heating, you can move way more than 100% heat with 100% electrical energy if you use, say, a heat pump.
Heat pumps are not viable in a lot of cases, in an urban setting, it's probably the vast majority.
So for the many cases were the alternative for heating would be burning fossil fuels, using electricity, ideally produced via renewable energy/nuclear, could be a superior alternative.
