Los Angeles gets country's first fully alt-fuel transit fleet

Metro is now the only major transit agency in the U.S. with a fleet run entirely on alternative fuels. Officials say the shift has sharply cut emissions of cancer-causing pollution. After almost two decades of effort to reduce vehicle emissions, the Los Angeles County Metropolitan Transportation Authority retired its last diesel bus Wednesday and became the only major transit agency in the nation with a fleet that is totally equipped with alternative-fuel technologies. In an urban area where diesel buses began operating in 1940, the MTA now has 2,221 buses powered by compressed natural gas, as well as one electric bus and six gasoline-electric hybrids. Transit officials estimate that the elimination of diesel engines has reduced the release of cancer-causing particulates from the bus fleet by 80% and greenhouse gases by about 300,000 pounds a day in one of the smoggiest areas of the country. MTA officials say that compressed natural gas buses cost more to buy and maintain than those powered by diesel but that the increased expenses are offset somewhat over the long run by lower fuel costs.

Solar Shutters

The PV Solar Shutter is a perfect fit because it requires no roof space and no large battery banks, and is very easy to install and uninstall. Each unit can purchase its own shutters, have its own power source, and offset usage one window at a time. Even renters can, like any other window covering, take their shutters with them if when they move.

Apple Gets Patent for Solar Powered Gear

The sun may be in your iPhone battery's future. Yesterday, Apple received Patent No. 7,868,582 from the U.S. Patent and Trademark Office for powering electronics partially with solar power. The patent, which was originally filed in 2009, describes a system of using a solar panel for charging different portable devices, including a notebook computer, tablet, phone, or other handheld gadget. It specifically deals with converting the power from a solar panel to meet the power requirements of electronics. The system includes a voltage converter that ensures the available solar power can be converted and used to recharge batteries. The solar panel could either be embedded in the device or be removable, according to the patent. Although Apple has not yet released any solar-powered gadgets, it's clear that the company is interested in letting people use sunlight to charge when they can't get to an AC outlet. It's the fourth patent that Apple has received related to solar power, according to Patently Apple.

Dow to showcase energy-savings at International Builders Show

Dow Chemical Co. is set to showcase its most recent energy-saving innovations at the International Builders' Show in Florida. The company's Building Solutions team will be displaying a range of insulation, air sealing and renewable energy solutions for homeowners. "Building a high performance home starts with sealing the building envelope," said Dale Winger, residential market manager, Dow Building Solutions, in a Jan. 5 news release. He added that the products on display would reflect the growing demand for more energy-efficient homes. Latest developments include a variety of spray polyurethane foam products to reduce air and moisture infiltration causes by gaps and cracks in buildings, as well a selection of rigid foam insulation designed to meet the needs of specific above-grade wall applications. As well as polyurethane and other foam solutions, the company will be showcasing its Dow Powerhouse Solar Shingles, a solar-power product for residential homes expected to be commercially available in the US market by mid-2011. IBS 2011 is one of the largest annual light construction shows in the world and will take place Jan. 12-15 in Orlando, Fla.

Chevrolet Volt wins 2011 North American Car of the Year

The 2011 Chevrolet Volt got another marketing jolt Monday, when it received the North American Car of the Year. The car that runs on electricity for 40 miles (65 kilometers) before a backup gas engine kicks in beat out the Nissan Leaf, another electric, and Hyundai Sonata in the annual ceremony on the first day of media previews for the Detroit auto show. Forty-nine auto journalists from the U.S. and Canada made the picks. The vehicles are judged on innovation, design, safety, handling, driver satisfaction and value. It's the latest in a string of accolades for the Volt, which went on sale in limited markets in December and costs $40,280. It was named the Green Car of the Year at the Los Angeles Auto Show in November and Motor Trend and Automobile Magazine named the Volt the 2011 car of the year the same month. General Motors Co. Vice Chairman Tom Stephens said the Volt "represents the soul" of the new GM, on the rebound after enduring a government-led bankruptcy in 2009. GM sold between 250 and 350 Chevy Volts in December and Nissan's sales totaled less than 10 Leaf sedans in the past two weeks. Production for both is slowly ramping up. It will be well into 2012 before both the Volt and Leaf, which costs $32,780, are available nationwide. Early demand is strong: About 50,000 people already are on waiting lists. The Volts are being assembled in Detroit. GM predicts it will sell 10,000 of them in 2011 and between 35,000 and 45,000 in 2012. By way of comparison, Chevrolet sold 187,250 Malibu sedans in the first 11 months of 2010 with sticker prices that start at $21,975.

'Self-repairing' solar cells described

U.S. researchers say they've produced a new class of solar cells that can repair themselves much like plants do through photosynthesis. By using carbon nanotubes and DNA, scientists at Purdue University have developed solar technology aimed at increasing service life and reducing cost, a university release said Tuesday. "We've created artificial photosystems using optical nanomaterials to harvest solar energy that is converted to electrical power," Jong Hyun Choi, a Purdue professor of mechanical engineering, said. Photoelectrochemical cells that convert sunlight into electricity contain light-absorbing dyes called chromophores, similar to chlorophyll molecules in plants, that degrade due to exposure to sunlight. "The critical disadvantage of conventional photoelectrochemical cells is this degradation," Choi said. The new technology gets around this problem in the same way nature does, by continuously replacing the photo-damaged dyes with new ones. "This sort of self-regeneration is done in plants every hour," Choi said.
