Qarnot Unveils a Cryptocurrency Heater For Your Home (techcrunch.com)

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.

      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).

      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.

      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.

    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 wouldn't be secret, so it won't be anything particularly sensitive.

      Of course if you really are talking actual efficiency than co-generation engines https://en.wikipedia.org/wiki/... are the way to go. The most logical version in the low density domestic situation, a sewerage digester https://en.wikipedia.org/wiki/..., basically a large tank where you kitchen and toilet waste initially go, to start breaking down prior to going to sewer, specifically to produce methane, which you then burn in a gas turbine engine generator http://newenergyandfuel.com/ht.... Not quite the best design because you want to use the exhaust gases to heat water or your house and the radiate heat from the unit in say a clothes drying room and of course the electricity to go to your house battery (better balancing of energy needs between needing heat and electricity, of course if you have a heated pool, you can see real advantage in a domestic methane co-generation plant). You could use the energy to power bullshit crypto generation but in reality it would probably be smarter to sell the electricity you generate from mud monkey poo (earth primate faeces) back to the grid. How much electricity, how big is your family (a subtle dig at Americans there) and how big is your methane generation tank, and if you cogeneration plant is sized accordingly, will drive how much money you save or make, depending upon electricity and hot water usage.

      In fact those kind of installations should already be mass produced for default installation but mud monkeys are such a backward short sighted species often not able to see much beyond their own genitals (methane is ten times worse than carbon dioxide but who cares, I don't own any underwaterfront property, I wonder if they will develop house snorkels first, surf zone, probably not).

    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 thing. Even a utility with aging plants isn't going to become obsolete anywhere near as fast as a mining rig.

    If you don't like finance, you can always put the money towards a solar install if you're setup for that to work. The beauty of the financial approach is that you can do it anywhere--even in an apartment.
