Clip-on wind turbine aims to supplement solar panels

By - August 1, 2013 5 Pictures
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.

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

By - July 23, 2013 7 Pictures
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.

Crowdfunded solar-powered classroom leaves the grid

By - July 5, 2013 3 Pictures
Aaron Sebens and his class of fourth-graders from the Central Park School for Children in Durham, North Carolina hit Kickstarter back in March to try and raise enough money for their classroom to go off-grid. A rather modest target of US$800 was smashed within a day by the kindness of the international community and, at campaign end, the kids found themselves with the handsome sum of $5,817 to spend on the purchase and installation of a roof-mounted solar energy harvesting system. A wind turbine was added to the shopping list, and just two months later, the 208ers threw a huge "Flip the Switch" party to celebrate leaving the grid. Sebens reports that the classroom has been running on renewables ever since. 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

UGE replaces 4K wind turbine with mysterious mid-range VisionAIR

By - May 22, 2013 7 Pictures
Urban Green Energy (UGE) recently unveiled its newest vertical-axis wind turbine, the VisionAIR, as part of an installation at the Beijing International Garden Expo. The company confirmed to Gizmag that the VisionAIR is replacing its former 4K turbine, last seen adorning the top of an EV charging station, as its standard mid-sized option for customers. Compared with the previous model, the new turbine's design aims for better efficiency at moderate wind speeds, which UGE plans to integrate with its hybrid energy projects. Read More
