Friday Power Links: Data centers, battery investments, UV LEDs – and a quite good commencement speech
UV LEDs: If you’re interested in more on what HB LEDs are being used for in the non-visible light spectrum, Cary Eskow covered it nicely in this .pdf issue of his Light Matters newsletter.
AC vs. DC: Earlier this week I mentioned a 4-hour webcast that included on AC- vs. DC-power in the datacenter. I was able to watch most of the debate and got a lot out of it, especially the Microsoft guy’s steely-eyed disdain for the idea of risking so much on DC power when much of the gains could be achieved by following best practices. Watch the archived debate here.
Welcome to Las Vegas - Home of the technology superpower you’ve never heard of According to this UK newspaper article in The Register, at one time the Enron boys had a plan to make a market in Internet bandwidth. They got as far as setting up a state-of-the-art data center in Las Vegas before Enron imploded. Switch Communications bought the 407,000 foot facility and will soon be opening what it claims is the most energy efficient, tightly packed data center on the planet, with power density of 1,500 watts per square foot. Switch plans to build 10 more facilities just like it.
Detroit 3 to get U.S. money for plug-ins – A big chunk of this money is slated for battery research. Plus, the media hoopla about GM’s extended-range electric car, the Volt, has been high this week, and not coincidentally Toyota said, hey, it’s coming out with a lithium ion battery EV in 2010, too! But this is just reiterating their previous announcement that they would have a limited, leased run of the cars. Nothing new here, except for one thing – Toyota is playing catchup to GM, at least in the PR department.
Finally, this is the season of graduations and sitting through tedious speeches. (I just sat through a high school commencement, in the sun, in 101F degree heat. I know high school can be hell, but this was a bit too literal.) It was a pleasure to read the commencement speech that JK Rowling gave at Harvard. Funny, interesting, and inspirational.
