Jet-engine inspired FloDesign boosts wind turbine output


BOSTON--Start-up FloDesign Wind, one of a number of companies looking to shake up the wind turbine business, said a prototype of its jet engine-inspired turbine was three times more efficient at converting wind to usable energy than traditional designs.
The Massachusetts-based company is seeking to raise a series B round of $25 million later this year to deploy and test the real-life performance of its 150-kilowatt turbines, said CEO Stanley Kowalski III at the Cleantech Forum conference here on Thursday.
FloDesign Wind last year was spun out of aerospace engineering company FloDesign, which has supplied components used in military helicopters and fighter planes. Using its expertise in aerodynamics, the company is developing a wind turbine that more resembles a jet engine than a typical three-blade turbine.
Its plan is to develop relatively small turbines and market them for use by businesses, communities, or wind farm developers. The company is now testing prototypes, a process that will take at least a year, Kowalski indicated.
"I think it's exciting that there's an oligopoly (among wind turbine suppliers)," he said during a panel on Thursday. "There is a resistance to change and that's how things disrupt and we hope to be one of the disruptors."
Utility-scale wind farms typically use giant wind turbines capable of turning out one or two megawatts of electricity--enough to supply hundreds of homes. By contrast, FloDesign wind--along with a
other wind challengers--is developing its turbine for use in locations not well suited for large turbines, such as mountain ridge lines, or to customers that want to make power on site, such as municipalities or businesses, Kowalski said.
