A great concept at the 2012 Los Angeles Auto Show is the Mercedes-Benz Ener-G-Force: a zero-emissions vehicle with zero tolerance for citizen misbehaviour. The Ener-G-Force is a police vehicle and a fuel-cell vehicle. It’s a Mercedes-Benz G-Class underneath, and channels the vibe of a G-Class off-roader circa 1979.
A streetscape that includes natural landscaping, bicycle lanes, wind powered lighting, storm water diversion for irrigation, drought-resistant native plants and innovative “smog-eating” concrete has earned Cermak road in Chicago the title of “greenest Street in America” according to the Chicago Department of Transport (CDOT). Opened in October 2012, the first phase two mile stretch is […]

When it comes to adopting new technologies, particularly solar, farmers and owners of agriculture-related operations have often led the way. Farmers make good pioneering cleantech users for several reasons: They have a lot of space to deploy first-gen technology, particularly for equipment that’s heavy and bulky; they’re heavy energy users who seek ways to reduce […]
After the big BPA scare of aught nine I decided to switch from using my Nalgene bottle, just to be on the safe side. Normally I’m not one to throw away perfectly good water bottles willy-nilly just because I heard that something might possibly be not the healthiest. At least, not without reading the research […]
The other ZEHST (zero-emission hypersonic airliner) model that was unveiled at the Paris Air Show 2011 was EADS’ VoltAir. VoltAir is an electricity-driven aircraft that could actually rule the skies in the next 25 years. This futuristic and innovative, all-electric airliner will function on two modified lithium air batteries that will have the capacity to […]
Solar panels aren’t the only option for homeowners when it comes to using renewable energy to cut power bills. Sales of wind turbines for backyards and rooftops are growing strong. There’s been major growth in the last ten years with more than 10,000 wind turbine units sold in 2009 compared to 2,100 units in 2001. […]
