On the Horizon and Here Today: LED Alternatives to Linear Fluorescents
March 4, 2008 09:08 AM - Glenn Hasek, Green Lodging News

NATIONAL REPORT—In meeting rooms, back of house and other areas of your hotel, chances are great that you are using T-12 fluorescent lamps or the more efficient T-8s to illuminate large spaces. At least two companies—ilumisys, Inc. in Troy, Mich., and LEDdynamics, Inc. in Randolph, Vt.—are trying to replace these linear fluorescents with LED alternatives that are more energy efficient and safer for the environment. Fluorescent tubes include mercury and despite recycling efforts, 500 million to 600 million lamps end up in landfills each year. LED alternatives do not include mercury.

Aging Hybrids Rejuvenated?

Both Toyota and Honda make excellent cars. The motors, the bodywork, the interiors, the transmissions, the electrical bits, all first rate. Sure, there are occasional problems, some expensive to fix, and sure, items wear out and have to be replaced, but both companies build cars that can be driven 150,000; 200,000 perhaps as much as 300,000 miles with a little love and care.

Body Heat…and Power

Concerns about climate change and greenhouse gas emissions are instilling a new dynamism –and fueling something of a renaissance - in alternative energy research and development. It’s increasingly apparent even to lay observers like myself that there’s potential energy – in widely varying degrees and at widely varying scales – in natural processes all around us.

Amazing solar shingles inspiried by leaves
March 2, 2008 08:42 AM - ENN

While the future of solar technology seems to rest on nanotechnological innovation, these GROW panels by SMIT are fairly remarkable. Inspired by leaves, these tiny generators do one better than their biological counterparts, drawing power from the sun, but also capturing energy from the wind as they are jostled by the breeze.

Richard Branson's new push, biofuels; coconut oil fueled airliner
March 1, 2008 09:18 AM - , Triple Pundit

Richard Branson, the business man that makes headlines seemingly every week. This time, it is for a green cause, he made history by becoming the first commercial airliner owner to fuel a flight with a partial load of biofuels. The debatable point is this, it took the oil of 150,000 coconuts and some babassu palm oil to power only 20% of one of four fat tanks on one of his 747 Virgin Atlantic airliners. The headlined trip launched at Heathrow airport and touched down at Schiphol airport in Amsterdam, making the mark on what some would claim could be a revolution in environmentally responsible aviation.

Physics lab completes world's largest jigsaw puzzle
March 1, 2008 09:05 AM - Reuters

GENEVA (Reuters) - A 100-tonne wheel, the last piece of an ambitious experiment that scientists hope will help unlock the secrets of the universe, was successfully lowered into an underground cavern on Friday. It is the final major element in the ATLAS particle detector, the largest of four detectors being hooked up to the world's most powerful particle accelerator which the European Organisation for Nuclear Research (CERN) hopes to start up around the middle of 2008.

Conti's lithium-ion cell to power Mercedes hybrid
March 1, 2008 08:06 AM - Reuters

FRANKFURT (Reuters) - Daimler's luxury brand, Mercedes-Benz, will launch an S-Class hybrid next year equipped with a lithium-ion battery supplied by Continental in what Daimler said on Friday was a crucial technological breakthrough. "The Stuttgart-based automaker is the world's first manufacturer to have succeeded in adapting lithium-ion technology to the demanding requirements of automotive applications," it said in a statement.

Keeping the Carbon In the Car
February 29, 2008 09:25 AM - , Green Pages

The Georgia Institute of Technology wants to make a hydrogen-fueled vehicle that separates and stores carbon dioxide until it can be sequestered The Georgia Institute of Technology has thrown one more idea into the mix: a zero-emission, hydrogen-powered car that would separate carbon dioxide from liquid fuel and gather it for sequestration underground or in the ocean. Further down the line, the scientists envision transforming that captured CO2 into more fuel, creating a sort of cycle.

Liquid water found flowing on Mars? Not yet
February 29, 2008 08:50 AM - University of Arizona

Liquid water has not been found on the Martian surface within the last decade after all, according to new research. The finding casts doubt on the 2006 report that the bright spots in some Martian gullies indicate that liquid water flowed down those gullies sometime since 1999.

Antarctic boulders may point to sea level rise
February 29, 2008 12:20 AM - Reuters

OSLO (Reuters) - Boulders as big as soccer balls show that a thinning of West Antarctic glaciers has become 20 times faster in recent decades and may hold clues to future sea level rise, scientists said on Friday. Rocks trapped in glacier ice start to react like clockwork when exposed to the air because of a bombardment of cosmic rays. Scientists studied boulders by three glaciers to find how long they have been out of the ice and so judge the pace of thinning.
