German researchers are testing a unique form of public transportation that borrows the best from busses, electric cars, trains and trams without contributing emissions. The vehicle, named AutoTram, is fully electric, but instead of running on a single charge, it charges when it stops, gaining enough power in 30 seconds to move another mile.
The project comes from the Fraunhofer Institute for Transportation and Infrastructure Systems IVI in Dresden and aims to offer the convenience, routing flexibility and affordability of a bus, minus the noise and exhaust. It also addresses the problem of lengthy battery charging cycles. While most cars are only in use for a few hours per day, public transportation vehicles can be in action around the clock, offering nearly no battery charging opportunities. → Read More
What’s more impressive than a car that can do over a thousand miles per gallon? One that was designed by school kids.
In the UK, students from regional schools and universities took part in the annual Mileage Marathon Challenge near Leicester, England, each team vying to set new gas mileage efficiency records in a race around a track. Cars were allowed to coast, but had to maintain a minimum speed of 15 miles per hour. Students worked on the vehicle prototypes, many in partnership with design and engineering firms. → Read More

Airplanes release greenhouse emissions into the atmosphere and require enormous amounts of fuel to fly. A Boeing 747 can consume up to five gallons of fuel per mile. But what if planes could be powered by electricity? Though they won’t replace passenger airliners anytime soon, small, zero-emission, electric planes are flying today.
Engineers have been pursing electric flight for decades. In 1979, the Solar Riser became the first manned electric aircraft to fly. It used photovoltaic cells to charge a battery that powered an electric motor, but could only fly five minutes, at which point it could either glide or land.
Many enhancements have been made since, and several models of electric planes are showing signs of promise. Two of the most interesting planes to fly recently are the E430 and the SkySpark. → Read More

A lot of green apps focus on offering general tips for everyday actions you can take to help make a difference, which really doesn’t take advantage of the iPhone’s capabilities. Below are the top ten green apps across a range of applications, some of which could help you save money in addition to living on the greener side of the fence. → Read More
A new charger from Horizon Fuel Cell Technologies can help power your gadgets when there’s nowhere to plug into but the sun.
The Sunbox USB has a panel that can be attached outside of a house or tent that connects to a box with several charging ports. Horizon claims the unit can power an LED light included with the device for as long as 11 hours, so long as the panel sees the six to eight hours of sun it needs for a full charge. → Read More
Most green technologies gather energy above ground, but like Jules Verne, we want to take you on A Journey to the Center of the Earth. Alright, not even close to the center, but deep down nonetheless, where naturally occurring hot water can be turned into clean energy above ground.
It is estimated that the amount of heat within 30,000 feet below the earth’s surface holds potentially 50,000 times more energy than all global oil and natural gas resources combined. According to the Geothermal Energy Association, up to 6,400 megawatts of new capacity could be created from the geothermal projects under development in the U.S. But getting to that energy is proving to be a challenge. → Read More
According to SEC documents, Entech Solar raised $6.95 million, primarily from Quercus Trust, which owns 54% of the company.
The Fort Worth, Texas based company makes concentrating photovoltaics and tubular skylights meant to replace office and school lighting with sunlight. → Read More
A Stanford University research group says it found a way to more than double current solar power production efficiency. The technology uses both light and heat from the sun and is inexpensive enough that, if it pans out, it might be able to compete with oil.
Most current technology can either convert light into electricity at relatively low temperatures, or convert the sun’s heat at very high temperatures. Stanford engineers claim they developed a way to do both. → Read More
Smart window startup Soladigm announced today its plans to build a factory in Olive Branch, Mississippi. The Khosla Ventures and Sigma Partners backed company makes dynamic glass windows that can be tinted on demand to block excess light and heat.
