Eco Whisper Presents a Unique Design in HAWT

There seems to be a lot of variation in the design evolution of the vertical axis wind turbine. But it's not every day that you see a dramatic design departure in horizontal axis wind turbines. So it is refreshing to see the news about the latest technology launched by Renewable Energy Solutions Australia.

It's rated at 20KW peak capacity with zero noise pollution and a low cut-in speed. The 30 blades (6.5 meter diameter) make it more visible to birds and bats. And it spins to capture the prevailing wind direction without the use of a tail fin. It instead relies on a "dynamic slew drive." While we're not entirely sure what that is and how reliably it functions, it certainly sounds impressive...or rather it sounds like a whisper.
