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.

    On a lighter note: Decades after NASA's Apollo missions, people are having some laughs over transcripts of astronauts' humorous conversations aboard the spacecraft. For all their technological sophistication, the Apollo command module had a relatively primitive system for managing human waste.
