Solar glazing chases sun from dawn until dusk

In the age of green energy we are seeing interesting new developments that marry building materials with the capacity to harness renewable power sources. Building integrated photovoltaic (BIPV) or concentrating PV technologies aren't new, but the ability to concentrate and maximize the capture of energy by tracking sunlight from dawn to dusk is. The Center for Architectural Science and Ecology CASE has unveiled a new Integrated Concentrating (IC) Dynamic Solar Facade which does just that - and it looks great! Read More

Honda's next gen solar-powered hydrogen fuel cell station for home use

Honda has begun work on a smaller solar hydrogen station prototype intended for use as a home refueling appliance. Capable of an overnight refill of fuel cell electric vehicles it is designed to be a single, integrated unit that will fit in the user's garage. Honda's next generation Solar Hydrogen Station, though not as big as the previous systems, will still produce enough hydrogen (0.5kg) via an eight-hour overnight fill for daily commuting (10,000 miles per year) for a fuel cell electric vehicle.

Calera and Novacem use concrete to capture CO2

Concrete seems pretty inoffensive. It just looks like mud, and appears to do nothing except sit there and harden. The fact is, though, concrete is the world's third-largest source of man-made carbon dioxide. Its production process accounts for at least 5% of the CO2 our species pumps into the atmosphere annually. Apparently, however, it doesn't have to be that way. Two companies are now using different technologies that not only make concrete carbon-neutral, they actually make it carbon-negative. Read More

Build your own electric car with Trexa

Trexa has revealed details of a lithium-powered, all-wheel vehicle development platform that will enable engineers and developers to create custom "vehicle apps", doing for builders of electric vehicles what the iPhone did for application developers. Modular and scalable, the standard Trexa platform will feature an aluminum, carbon steel tubing and thermoplastic shell containing open source and user programmable electronics and advanced battery technology.

Computer modeling indicates white roofs may be a cool idea

Previous studies have indicated that painting the roofs of buildings white could be a low tech way to reduce global warming by reflecting the sun’s rays back into space. Now the first computer modeling study to simulate the impacts of white roofs on urban areas worldwide has added more weight to such a proposal indicating that painting every roof in a city entirely white could cool the world’s cities by an average of about 0.7 degrees Fahrenheit or 0.4 degrees Celsius.

Healing of ozone hole could accelerate global warming

You'd think the healing of the hole in the ozone layer would be good news, but it seems that although every cloud is said to have a silver lining, they also have a gray one as well. The Antarctic ozone hole was once regarded as one of the biggest environmental threats, but researchers now argue that the ozone hole over Antarctica helped to shield this region from carbon-induced warming over the past two decades and its repair could actually increase warming in the southern hemisphere.

Sanyo Eneloop bike up close and personal at CES 2010

We met with Sanyo's David Cabanban Sanyo at CES 2010 and he was kind enough to speak to us about the recent Sanyo-Panasonic alliance as well as Sanyo's new solar panel that is translucent, allowing it to capture solar energy not only from on top of the panel, but also from light reflected off the ground. David also took us through the finer points of the eneloop bike we first spied in December 2008 and we jumped aboard for a test ride. The bike features impressive power-assisted technology that amplifies the rider's pedaling, making cycling up hills or at speeds of up to 15mph that much easier. Read More

Old tires find new life in cow mattresses

Cows have it hard. They’re bred to be empty-headed, they have to stand outside in the heat and cold, extraterrestrials occasionally do nasty things to them, and ... well, we won’t talk about what ends up happening to many of them. It’s nice, therefore, to see someone cutting the cows a break. Champagne Edition Inc, based out of Alberta, Canada, manufactures mattresses for the comfort and health of cattle. What’s more, they make the mattresses out of old tires, that might otherwise end up in a landfill. Read More
