Ya know it amazes me that WNDT is adding other technologies to the tamer to make it more viable. Batteries, solar, the hydrogen crap that knownothing was selling us...all the while the product Brock touted as the miracle turbine is still just morphing into a pig with lipstick.... the costs of this design is not affordable for the clients...nor does the ducted element create so much energy that it even justisfies making it. Smarter people have already done this in the past... MFerraro
