America's "greenest street" provides a blueprint for sustainable urban development

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 part of the Blue Island/Cermak Sustainable Streetscape project which was introduced in 2009 with the aim of reducing overall energy usage by 42 percent.

EnergySails harness wind and solar power to cut ship fuel consumption

In the 400 years or so leading up to the adoption of steam power in the 19th century, sailing ships ruled the waves. In an effort to cut increasing fuel costs and reduce emissions, sails are set to once again prove their worth. But unlike the sails proposed by B9 Shipping and the Wind Challenger Project, Japan-based Eco Marine Power (EMP) is developing sails with an even more modern twist. Rather than just harnessing the power of the wind, EMP’s EnergySail can be fitted with solar panels to also harness solar power. Read More

Kite power getting off the ground in Germany

Despite offering numerous advantages over its rotating brethren, most notably the ability to reach the high-speed winds found at higher altitudes, kite-based energy systems are yet to really get off the ground in a meaningful way. But things are looking up. Earlier this year, NASA revealed it is investigating ways to improve the aerodynamics and autonomous flight control of kites for power generation applications, and now Berlin-based wind energy developer NTS GmbH has teamed with the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA) to make their own kite energy system concept a reality.

DARWIND5 wind turbine improves on an old design

Ontario, Canada has carved out a niche for itself as a hub of green technology. One of the latest clean tech innovations to come out of that province is DARWIND5, a vertical axis wind turbine (VAWT). Designed by Harvistor, it comes with a promise of more oomph than existing models for small-scale wind power generation. According to the company, recent tests showed that its technology can achieve 35 percent more kilowatt hours per year than current VAWTs for the same sweep area, besides operating at 25 percent lower heights than similarly priced market leaders.

WWII veteran creates bird-friendly wind turbine

World War II veteran Raymond Green, an 89 year old resident of Jackson, California, has created a working prototype of a "bladeless" wind turbine which is bird and bat-friendly, and very quiet in operation. Though still in development at present, Green intends his design to be produced in various sizes, from smaller personal versions to much larger turbines which could be implemented in wind farms.
