INF hardware NRG energy data mining

  • For Hewlett Packard Fellow Chandrakat Patel, there’s a “symbiotic relationship between IT and manure.”
  • Patel is an original thinker. He’s part of a group at HP Labs that has made energy an obsession. Four months ago, Patel buttonholed former Federal Reserve Chairman Alan Greenspan at the Aspen Ideas Festival to sell him on the idea that the joule should be the world’s global currency.
  • Data centers produce a lot of heat, but to energy connoisseurs it’s not really high quality heat. It can’t boil water or power a turbine. But one thing it can do is warm up poop. And that’s how you produce methane gas. And that’s what powers Patel’s data center. See? A symbiotic relationship.

  • Financial house Cantor Fitzgerald is interested in Project Moonshot because it thinks HP’s servers may have just what it takes to help the company’s traders understand long-term market trends. Director of High-Frequency Trading Niall Dalton says that while the company’s flagship trading platform still needs the quick number-crunching power that comes with the powerhog chips, these low-power Project Moonshot systems could be great for analyzing lots and lots of data — taking market data from the past three years, for example, and running a simulation.

    ocean fertilization might induce increased marine aerosol (DMS) emissions leading to further cooling effect but also changes in precipitation

    first time I hear about this!!! Is there any peer reviewed paper reference to this? should impact missions like GOCE!!
  • Nina Nadine Ridder on 08 Dec 09
     
    There are (even in Science): http://science-mag.aaas.org/cgi/reprint/314/5803/1253.pdf There is also a group at UCAR (lead by S. Solomon, one of the Gods in atmospheric research) who are analyzing this effect: http://www.ucar.edu/news/releases/2006/thermosphere.shtml

    for the drag effect, this is well known in fluid mechanics, we use the Knudsen number, which explains this phenomenon ... for a perfect gaz though!

    No. People SHOULD look at alternative views to be more informed. Criticism of areas of science is a GOOD thing, it helps science to grow. Unfortunately, when it comes to this issue, people, including ACT members have a closed mind and do not want to listen to alternative view points. But I am sure many people in the group have seen it before. Have you?

    This is why i always post crazy stuff .... its disruptive. ..... although sometimes its a joke ;)

    For the first time, researchers have shown that they can capture CO2 from the air, and convert it directly into methanol, which can then be used as an alternative fuel, as well as for hydrogen storage, in fuel cells, or as a building block for plastic.

    Solar power to suck out co2 during the day and make it fuel finally solves global warming?
