Wind Lens Turbine Design
The way to go?
The more I read about the "wind lens" turbine design, the more convinced I become that this is not a "snake oil" deal like EEstor and their "vapour ware" super battery.
Some fair sized upscaling of the design is now taking place. The brim could also keep the "BATTY" people happy, as a net could be stretched over it thus saving wildlife from becoming sushi!!
