Clip-on wind turbine aims to supplement solar panels

Crowdfunding has come to the small wind generation field with an Indiegogo campaign intended for an interesting target niche: a small wind generator designed to be clipped onto solar panels. According to his pitch, Michael Ring has not only created a prototype, but calculated possible energy returns, targeted a price point and lined up suppliers for initial deliveries and has turned to Indeigogo to get his small startup off the launch pad.Read More

Opinion: Are "school of fish" turbine arrays a red herring?

Since we first looked at John Dabiri's hypothesis that vertical axis wind turbines should be arrayed like a school of fish to reduce the land area required for wind farm installations, the MacArthur Genius Grant recipient has continued to work on the idea. Following the latest round of coverage, Gizmag takes a deeper look at his concept, and wonders whether the idea of packing turbines into as tight a space as possible might overlook some wind energy fundamentals.Read More

Delft explores kite power for rural Africa

The University of Delft has a program devoted to kite-based generation systems, with 20 years of research and development under their belt since Wubbo Ockels, the first Dutch astronaut established it. Now, members of the team are exploring practical niches where the compromises of kite-based power might pay off. One has just completed a trip through Kenya, Tanzania and Senegal discussing opportunities for rural African kite generation with governmental agencies, universities and companies in the renewables space.Read More

Dodgy wind? Why "innovative" turbines are often anything but

Virtually every week there are articles about new and innovative methods for harvesting wind energy. And every week more megawatts of capacity from three-blade horizontal-axis wind turbines (HAWT) becomes operational, despite all of the contenders. Why aren't these innovative new products knocking the iconic HAWT off its perch? Is it possible to tell which are likely to be viable? These eight points are a useful way to assess which technology has potential, and which are likely just hot air.Read More
