EcoATM pays you for your used mobile phone

By - October 6, 2009 0 Pictures
Even though many people are aware of the importance of recycling their mobile phones, it is reported that only about ten percent of used phones actually make it into a recycling program. Would people be more diligent with mobile phone recycling if it was not only convenient, but lucrative as well? An EcoATM machine currently being trialed in Nebraska, accepts your used mobile, scans it to assess its market value and rewards you with a retail coupon or gift card. Read More

Google investigating smart charging solution for electric vehicles

By - October 5, 2009 2 Pictures
A lesser-known fact about the operator of the world's most popular Internet search engine is that it's been running a small fleet of hybrid vehicles for the past few years to support its effort to reduce CO2 emissions, cut oil use and stabilize the electrical grid by accelerating the adoption of plug-in electric vehicles. Google engineers have put the cars through numerous tests to both prove and improve electric vehicle technology whilst publishing the results on the Internet. More recently, Google has confirmed that the fleet is currently running smart software to enable communication between the grid and the vehicles. Read More

Helix looking to use mobile phone towers for wind energy generation

By - October 3, 2009 5 Pictures
Later this month, Helix Wind Corporation will deliver its first test wind turbines to Eltek Network Solutions Group for installation at two test sites in Nigeria. Sites in the US are also set to take delivery of test modules. The turbines will provide a clean energy solution for mobile phone towers and if tests prove successful, could see wind power being rolled out to hundreds of sites over the next few years. Read More

New 'green' geopolymer concrete delivers win-win for industry and the planet

By - October 2, 2009 1 Picture
Concrete is the most prevalent building material on the planet, and though the world would be pretty flat without it (not many tall buildings and structures), it does come at a price – around 5-8 percent of all human-generated atmospheric CO2 comes from the concrete industry. A culprit is Portland cement, the binding agent in concrete. It’s the most widely produced man-made material on earth. Production of Portland cement is currently exceeding 2.6 billion tons per year worldwide and growing at 5 percent annually. To halt these alarming pollution figures, innovative research on geopolymer concrete, along with ways of using a waste byproduct from coal-fired powerplants, is being conducted by Dr Erez Allouche, assistant professor of civil engineering at Louisiana Tech University and associate director of the Trenchless Technology Center.

Populous unveils stunning design for 2014 Winter Olympic Stadium

By - October 1, 2009 2 Pictures
Global design company Populous has been selected to design the main stadium for the 2014 Winter Olympic and Paralympic Games to be held in Sochi, Russia. It will seat up to 40,000 people and is expected to incorporate a number of eco-friendly features. Echoing the striking Beijing Olympic swimming venue, the exterior of the stadium will be sheathed in a crystalline skin which will be translucent during the day and come alive at night with the color and spectacle we have come to expect from modern-day Olympics.

Trashing existing fuel sources could cut global emissions by 80%

By - September 30, 2009 1 Picture
If there’s one thing there seems to be an endless supply of, it's garbage. The idea of turning the trash that currently ends up in landfill into a fuel to combat the growing energy crisis and tackle carbon emissions isn’t new. Companies like Waste2tricity in the UK are already looking to convert waste from business and industry into clean electricity. Now scientists in Singapore and Switzerland have added credence to the idea, saying that replacing gasoline with biofuel derived from processed waste biomass could cut global emissions by 80%.

Color matters: GreenSun Energy colored solar technology

By - September 24, 2009 4 Pictures
One of the most common ways to turn the sun's energy into electricity is by persuading silicon to give up some of its electrons. But it's also quite expensive, so any innovation that helps reduce the cost of solar cell production is welcome. Researchers in Israel have come up with a cell that uses only 20% of the silicon in a standard cell yet yields similar amounts of electricity. It does this by diffusing any light that falls on its surface and sends it off to photovoltaic collector strips on each of its sides. And it doesn't even need bright sunlight to operate. Read More

Keeping hybrids cool under the bonnet reaches boiling point

By - September 23, 2009 1 Picture
As an increasing number of hybrid-powered vehicles move from concept to completion, technology is battling to keep pace with some of the less-publicized technical challenges found among the complex electronics aboard these land- and air-based vehicles, computers and other devices. For instance, how do you effectively cool the electronics in a high-power electric motor that propels a passenger car from 0-60mph in under 10 seconds and uses regenerative braking to stop? Researchers in the U.S. believe the secret may lie in understanding precisely how fluid boils in tiny ‘microchannels’, which has led them to develop formulas and models that will help engineers design unique systems to cool high-power electronics found in today’s and tomorrow’s devices.
