Qarnot Unveils a Cryptocurrency Heater For Your Home (techcrunch.com) 65
Qarnot, the French startup known for using Ryzen Pro processors to heat homes and offices for free, is unveiling a new computing heater specifically made for cryptocurrency mining. "The QC1 is a heater for your home that features a passive computer inside," reports TechCrunch. "And this computer is optimized for mining." From the report: The QC1 features two AMD GPUs (Sapphire Nitro+ Radeon RX580 with 8GB of VRAM) and is designed to mine Ethers by default. You can set it up in a few minutes by plugging an Ethernet cable and putting your Ethereum wallet address in the mobile app. You'll then gradually receive ethers on this address -- Qarnot doesn't receive any coin, you keep 100 percent of your cryptocurrencies. If you believe Litecoin or another cryptocurrency is the future, you can also access the computer and mine another cryptocurrency. It's a Linux server and you can access it directly. If your home is cold and you desperately need to turn on the heaters, the QC1 is going to turn on the two GPUs and mine at a 60 MH/s speed. There are also traditional heating conductors in case those two GPUs are not enough. Qarnot heaters don't have any hard drive and rely on passive heating. You won't hear any fan buzzing in the background. You can order the QC1 for $3,600 starting today -- you can also pay in bitcoins. The company hopes to sell hundreds of QC1 in the next year.

I'm thinking generating supplemental heat for a water heater might be more useful in the summer.

Propane is used to power refrigerators and A/Cs in RVs using absorption refrigeration techniques (the old ammonia cycle concept but with safer fluids today). Since any heat source would work, I would think these systems could be adapted to utilize heat from GPUs. The fluid could be circulated straight through the heat sink.

After spending $3600 on the unit, how long will it take at average mining rates to recover your investment, and after that does it mine enough per hour to pay for the electricity used to run the unit?
I mean, I'd gladly sell a device that paid out a penny a day for only $3600. The customers would break even in only 986 years, and after that it's pure profit!
Yup, P.T. Barnum greatly underestimated the sucker proliferation rate.

This is only true if you use electricity for heating, which is generally a dumb thing to do.
If fuel is available, it is better to use it directly to generate heat, rather than using it to generate electricity, and then using the electricity for heat. Or even better, to co-generate both heat and electricity.
If fuel is not available, and you really have to use electricity for heat, it is most likely going to be better to run a heat pump rather than a GPU.
But this seems to be targeted toward dumb people anywa

Dumb perhaps, but common practice in apartments - they often don't even have a gas pipe. You need to either deal with the hassle of propane tanks, and lose half the output to ventilation to get rid of the carbon dioxide they produce, or just use an electric heater.

I am currently mining with my PC and my house is heated by it. So, as someone who already does it, I can tell you that it's awesome during winter, and then it sucks hard, because you need to cool your house more than when not mining, obviously.
So unless you live somewhere in Iceland or up in the mountainside, you will only heat your house half the year, effectively doubling your ROI time.
Shortly put: those 3600 dollars? Most of them you'll never make back.

If you are already heating with electricity, your "cost of electricity" is effective $0.00/kwh rather than $0.10/kwh since you are paying for the energy whether you run this rig or not.
Using http://whattomine.com/coins?ut... [whattomine.com] it seems like right now the system would generate $3.27/day working on Ethereum(ETH), so it would take 1101 days of heating to generate the $3,600 purchase price. That's 3 years and 5 days of heating - much better than the 3 years, 8 and a half months if you are paying $0.10/kwh, but st

There is that.
I was just looking at a client's office where a system doing file backup duties is located in a space that is heated by electricity. For the most part, the system is idle as the scheduled backup tasks are not running constantly and don't actually use a lot of computing power. We have considered setting up something like mining software or Folding@home to do something useful with some of the energy being used to heat the space. Not running the software in the summer would be a good idea. One sh

The most interesting use of processing power for mining a cryptocoin I've heard of is Render Token. Instead of trying to find an arbitrary hash, the processor renders 3d graphics as part of a cloud-computing job. Thus, useful work is accomplished. However, I'm unsure why the cryptocoin angle is necessary when it could be given a standard monetary reward. Presumably each frame rendered has to be verified by another worker to ensure you didn't cheat in the rendering, and the contents of the scene/render would

Only relatively warm climates use electricity for heating because the cost is just too high once you have to run the heat more than a few weeks out of the year.
That said, if you're going to mine anyway, might as well do it in the winter as the heat produced will be useful instead of wasted. It's definitely not "free heat" if you normally use gas or oil to heat your home, though.

To know whether "$3600 + electric bill + BitCoin-conversion" (assuming this is only good for the winter months of 1, maybe 2 years) is better than just heating your house with gas or a heat pump we need to know what the consumption and bitcoin generation speeds.
My heating costs are about 3c/kWh and BTC is not worth my investment of time and money, but I know most people use gas or electric at much higher rates. Unless this optimized the rate of production, not sure if it's worth.

Brand new heat pumps these days are efficient down to 20-something Fahrenheit. Mine is 15 years old and the cutoff where it will no longer provide sufficient heat (with a modern smart thermostat controlling the secondary gas stage) seems to be about 30F but then again my house is currently very badly insulated (R13 in the attic).

Compare the efficiency of resistive heat to a heat pump.
Heat pump is several times more efficient at producing the same amount of heat.
So yep, most of the electricity will be converted to heat, but in a very inefficient manor.

If you're heating your home you'd be paying that electric bill anyway. Whatever work is done in the meantime, ultimately the machine will convert pretty much 100% of the input watts into watts output as heat.

Many utility stocks yield in the 4 to 5% range. At 5% yield, a $4000 purchase of shares yields $200/yr. Depending on your rates, this might be close to paying for what a cheap $100 resistance heater would consume, or it might not. YMMV depending on how often you use such things.
Of course stocks aren't risk-free; but you don't even have to chose your local utility--you can evaluate your appetite for risk in the market. I think in most cases, a good utility stock is far more likely to hold value than this
