Germans Can Get Free Heating From the Cloud

judgecorp writes The idea of re-using waste server heat is not new, but German firm Cloud&Heat seems to have developed it further than most. For a flat installation fee, the company will install a rack of servers in your office, with its own power and Internet connection. Cloud&Heat then pays the bills and you get the heat. As well as Heat customers, the firm wants Cloud customers, who can buy a standard OpenStack-based cloud compute and storage service on the web. The company guarantees that data is encrypted and held within Germany — at any one of its Heat customers' premises. In principle, it's a way to build a data center with no real estate, by turning its waste heat into an asset. A similar deal is promised by French firm Qarnot.

      Heat can be used to run air conditioners too if the temperature of the heat is high enough. Connect the heat output to a Sterling engine connected to a compressor or pumps for evaporative AC. This waste heat might also supplement the heat source for water heaters. I assume buildings in Germany have restrooms where folks can wash their hands. Some may even have showers.

      The additional cost for renewables for German consumers in 2014 is 6.24 ct/kWh (and parts of the industry is exempt) which is less than other taxes paid on electricity. While solar is still expensive (but went down a lot) wind is clearly one of the cheapest source of energy.

      Well, if you're concerned about security you shouldn't be putting stuff in "the cloud" to begin with - it's far more likely that a crooked IT guy at the hosting company will be compromising your data than the random guy whose house contains the servers you're using today. As for reliability - that would be a mixed bag. Software wise, assuming redundant virtualized servers, etc. reliability should be largely unaffected. If anything it should increase since a single localized disaster can't take out nearly as much hardware at once. Hardware-wise, you will see longer down times due to house calls but that's visible primarily to the hosting company, not the customer, and the cost is likely negligible compared to the rent savings.

    I don't know jack about their actual achitechture but, if they do it right, then the loss of any one group of nodes wont matter.

    If that is the case, then this actually makes them highly resiliant to this problem. Lets say to actually shut them down meaningfully means shutting down 20 households. That is 20 warrants, at 20 properties, probably some number of jurisdictions, its a lot more work....and basically, wont happen accidentally because someone was an idiot.

    If you come out with a new gen that makes less heat it means it can be more dense so the overall heat per racks stays at least similar (and often goes up). You would need something where the next gen produces less heat but is more sensitive to it to produce an optimal next gen that puts out less heat.

    Server racks have been stable in power usage for quite a while. Generally speaking, if they cut the power consumption per 'X' computational measure(flops, CPUs, memory, etc...) in half they'll simply double the density of that computational measure.

    Besides, you're probably looking at a 3-7 year upgrade cycle on these racks. I'm sure they don't want to touch them too often.

    Such a confiscation would require reaching though multiple jurisdictions...

    One of the things the last 15 years should have taught us is to never trust the authorities to follow the 'law'. They can make it up as they go along. Many of these raids are just plain punitive shakedowns in nature, like a mobster breaking your kneecaps or kidnapping the wife and kids. Oh, you may be found 'innocent' in the end, but just try to get your time and money back.
