"Before long, we will look back and wonder how we made important decisions or discovered new opportunities without systematically learning from all av

A new technique could pave the way for improving the workhorse lithium ion battery used in automobiles, cell phones and other devices so that it can recharge in seconds RAPID RECHARGE: Scientists tweaked a battery material to permit a super-quick flow of charge-carrying ions in and out. A new twist on the familiar lithium ion battery has yielded a type of power-storing material that charges and discharges at lightning speed. The finding could offer a boost for plug-in hybrid and electric vehicles and possibly allow cell phone batteries to regain a full charge in seconds rather than hours. Scientists at the Massachusetts Institute of Technology (M.I.T.) report in Nature today that they devised a way for lithium ions in a battery to zip in and out about 100 times faster than previously demonstrated. "We took a basically great material called lithium iron phosphate [LiFePO4] and we tried to improve it further," says study author Byoungwoo Kang, a graduate student in M.I.T.'s Department of Materials Science and Engineering.

The trip from Salt Lake City to southern Utah's red-rock playground-thousands of us make the drive to Moab during a typical year-will never be the same. There, where U.S. Highway 6 starts its cut through Spanish Fork Canyon, stand nine breathtaking, milk-white giants-the busily whirring turbines of the Spanish Fork Wind Project. The windmills are 405 feet high, and their blades, which from ground level look deceptively slow moving, spin at 170 mph, says Spanish Fork Mayor Joe Thomas. He should know. Shortly before the official ribbon cutting at the wind farm in early October, Thomas got the chance to climb to the top of a turbine.

By office office office office office building green-and retrofitting existent buildings-the countries of North America could cut hothouse gas emissions by some-more than twenty-five percent North American homes, offices as good as alternative buildings minister an estimated 2. 2 billion tons of CO dioxide to a ambience each year-more than a single third of a continent's hothouse gas wickedness outlay. Simply constructing some-more energy-efficient buildings-and upgrading a insulation as good as windows in a existent ones-could save a whopping 1. 7 billion tons annually, says a brand brand new inform from a Montreal-based Commission for Environmental Cooperation( CEC), an general classification determined by Canada, Mexico as good as a U. S. underneath a North American Free Trade Agreement to residence continent-wide environmental issues.

What better way to save the world than to start in your own back yard? That's what Doug Rempel is doing - one SIP at a time. Doug is currently building an entirely energy efficient home next to Lillooet Lake, in Pemberton, B.C. The home is "off the grid" which means everything, from the solar insulation panels (SIPS) to the architecture of the home - with window levels and patio ledges based on sun path charts - is created to heat and cool in the most natural way possible. There is no hydro power or natural gas. "Energy-efficiency is a career as well as a passion of mine," says Doug.

The (UK) Telegraph has an article on the Vivace tidal / current power device I mentioned recently - Ocean currents can power the world, say scientists The technology can generate electricity in water flowing at a rate of less than one knot - about one mile an hour - meaning it could operate on most waterways and sea beds around the globe. Existing technologies which use water power, relying on the action of waves, tides or faster currents created by dams, are far more limited in where they can be used, and also cause greater obstructions when they are built in rivers or the sea. Turbines and water mills need an average current of five or six knots to operate efficiently, while most of the earth's currents are slower than three knots.

Scientists say that a type of rock found at or near the surface in the Mideast nation of Oman and other areas around the world could be harnessed to soak up huge quantities of globe-warming carbon dioxide.

"As fossil fuel prices rise, as oil insecurity deepens, and as concerns about climate change cast a shadow over the future of coal, a new energy economy is emerging in the United States,"� says Lester R. Brown, President of the Earth Policy Institute, in a recent release, "New Energy Economy Emerging in the United States"� . "The old energy economy, fueled by oil, coal, and natural gas, is being replaced by one powered by wind, solar, and geothermal energy. The transition is moving at a pace and on a scale that we could not have imagined even a year ago."�

Energy independence is still only a hypothetical goal for the U.S., but the owner of a tiny island off the coast of Connecticut says he has already achieved that feat and is offering his work as a model. Dean Kamen, inventor of the Segway and numerous medical devices, jokingly refers to his North Dumpling Island as an independent nation and himself as Lord Dumpling. Kamen claims to have his own currency and offers visas to visitors to the tiny island a few miles from Mystic, where he is the only resident.

Expatriate Australian solar power company Ausra was one of the companies that featured heavily in my post on concentrating solar thermal power earlier in the year. California Governor Arnold Schwarzenegger has opened Ausra's first plant, a 5 MW plant at Kimberlina in central California (the first to open in 20 years) which will generate enough electricity during peak hours to power 3,500 homes. Ausra's next plant will be a 177 MW plant nearby in San Luis Obispo County. The SMH quoted Schwarzenegger as saying "This next generation solar power plant is further evidence that reliable, renewable and pollution-free technology is here to stay, and it will lead to more California homes and businesses powered by sunshine. Not only will this large-scale solar facility generate power to help us meet our renewable energy goals, it will also generate new jobs as California continues to pioneer clean-tech industry".

Researchers developing alternatives to fossil fuels are working with everything from algae to babassu oil to corn, but a California company says it can recycle carbon dioxide into fuel. Carbon Sciences claims it has developed a way of using the CO2 emitted during the combustion of coal, oil and other hydrocarbons to create transportation fuels like gasoline and jet fuel. Should Carbon Sciences - or any of the other firms working on similar projects - accomplish this on a large scale, it could bring a reduction in CO2 emissions as well as an abundant supply of renewable fuel.

"Our opponents say, again and again, that drilling will not solve all of America's energy problems - as if we all didn't know that already. But the fact that drilling won't solve every problem is no excuse to do nothing at all.

Scientists working at Arizona State University's Laboratory for Algae Research & Biotechnology hope that tiny algae will be able to fuel jumbo jets. Now, their research is being spun-off as a $3 million research and commercialization collaboration between Heliae Development and Science Foundation Arizona to develop, produce and sell kerosene-based aviation fuel derived from algae. The researchers say they've already moved their work from the lab bench to a pilot-scale demonstration and production project.

Vermont's four largest electric utilities believe the state needs new generating plants to replace at least some of the power they buy from outside sources. As VPR's Ross Sneyd reports, the companies say the plants should be powered by renewable energy, such as wood or wind.

ntel on Thursday showed off a wireless electric power system that analysts say could revolutionize modern life by freeing devices from transformers and wall outlets. Intel chief technology officer Justin Rattner demonstrated a Wireless Energy Resonant Link as he spoke at the California firm's annual developers forum in San Francisco.

By changing the way that conventional silicon solar panels are made, Day4 Energy, a startup based in Burnaby, British Columbia, has found a way to cut the cost of solar power by 25 percent, says George Rubin, the company's president.
