Bobbing for Energy in the Pacific Northwest
December 17, 2007 4:50 am | CommentsEnergy News: Most of Earth's surface is covered with free, green, non-depleting energy -- the movement of ocean waves -- and scientists say that power could be a major contributor to electric grids if only it were easily captured. So, researchers at universities such as Oregon State, and at start-ups such as Finavera Renewables and Ocean Power Technologies, are experimenting with special buoys that transfer movement into energy.
Smithsonian Plans LED-Spangled Banner
December 5, 2007 6:36 am | CommentsEnergy News: The 40-ft. x 32-ft. American flag defended at Fort McHenry in 1814 was made just a few years after the dawn of the incandescent lamp, and now Smithsonian preservationists will protect it further with modern LED technology.

Energy From Your Tranquil Pond
November 30, 2007 11:24 am | CommentsEnergy News: There are biofuel critics who say America can never grow enough raw material for the technology to be affordable and ubiquitous, but some scientists believe algae is a better option. At the University of Minnesota, they're figuring out how to make algae grow very fast, and how to get up to 15,000 gallons of oil per acre -- that is 750 percent more yield than
Get Your Low-Energy Computing with a Catch
November 27, 2007 11:21 am | CommentsEnergy News: Three stories about energy efficiency, focusing on computers, landed in my inbox today -- with a big fat asterisk attached. The stories are: Google Plans Renewable Energy Push -- they want to make one a gigawatt of clean energy cheaper to produce than the same amount of coal; HP Enters Two Renewable-Energy Contracts -- they're using solar and wind power for facilities in San Diego and Ireland; and Climate Savers Computing Initiative Empowers Smarter Computing Choices -- there's an online catalog of green desktops and servers, but it's only for companies that pay to join
Gone With the Wind, Part 2: Maglev Tech
November 27, 2007 5:44 am | CommentsProductive Product: What if you could eliminate all of the material friction in a windmill? (And why is this our third consecutive Efficiency Zone lead in question form?) No ball bearing is that good, but you could use maglev technology to just suspend the turbine blades in air. Magnetic levitation is more common for high-speed train research
Gone With the Wind, Part 1: The Sailboat
November 27, 2007 5:40 am | CommentsProductive Product: It was good enough for Columbus, Magellan, and Ellison, but is wind power -- the sail -- better in some cases than modern engines for oceanic cargo ships? A few companies are voting affirmatively. A blogger for Network World writes, "A kite the size of a football field will provide most of the power for a German
Nuclear Bathtub Full of Controversy
November 26, 2007 5:57 am | CommentsProductive Product: What if nuclear power were mass-produced in portable battery-like containers? That's the mission of Hyperion Power Generation, a start-up based on the research of Los Alamos National Labs scientist Otis Peterson. The bathtub-sized device with no moving parts could power 25,000 homes for five years, and Hyperion is poised to build 4,000 around
Utilities' Perspectives on Green Biz
November 26, 2007 5:29 am | CommentsEnergy News: "Making a Business of Energy Efficiency: Sustainable Business Models for Utilities" is the topic of next month's Edison Electric Institute meeting in Washington.
