The cell, built by Medis Technologies, is - at least in concept - similar to a glow-stick or a hand-warmer. The user squeezes the cell to mix two chemicals together, and the unit runs until the chemicals are exhausted - about 40 hours. It comes with an assortment of connector tips, including those for USB ports, BlackBerrys and cellphones of various other models, MP3 players and similar devices. The company hopes to soon manufacture a version big enough to run a laptop computer, and later one that could run a whole house.
Google wants to build the platform for collecting, managing, and analyzing home energy information for… well, if they have their way, for everybody on earth. PowerMeter is currently in internal beta testing. About four dozen Google employees have home energy monitors to record their power usage (as proxies for the smart meters of the future). A Home Energy gadget on their iGoogle home pages shows them shows how much energy they are using. The gadget tracks historical data and forecasts future trends (similar to the displays available for some of Google's finance applications).
The National Center for Atmospheric Research (NCAR) has reached an agreement with Xcel Energy to provide highly detailed, localized weather forecasts to enable the utility to better integrate electricity generated from wind into the power grid. The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) will support the project by developing mathematical formulas to calculate the amount of potential energy produced by winds blowing at various speeds. The forecasts will help operators make critical decisions about powering down traditional coal-and natural gas-fired plants when sufficient winds are predicted, allowing the utility to increase reliance on alternative energy while still meeting the needs of its customers.
