Local engineers find way to lower computer network costs: DC power

Data Center power

Engineers at the Lawrence Berkeley National Laboratory and some technology company partners have demonstrated that DC power distribution in computer data centers can save up to 15 percent or more on energy consumption and cost.

Better yet, it can be done with commonly available products. Could it be an example of what Silicon Valley venture capitalist Rob Day says here is the sort of business that could and should be done now? In other words, one that will help lower energy costs and do good by mitigating global warming? Rob says it again here this morning (he is practicing what he is preaching, judging from his latest investment).

  • DC power is a bit like the rotary engine. A great idea but you pretty much have to have a GOOD reason to use it.

    This is Rackable System's claim to fame. They can fit more machines in a rack if they use DC and save power. The problem is that NO ONE has DC... you seriously limit your choice of hardware if you use DC.

    Its becoming a problem though so maybe more people will install DC power...
  • I've been saying this all along, DC is superior to AC.
