The electric solar wind sail, or electric sail for short, is a new,
revolutionary method for moving in deep space. The electric sail
promises to solve a long-standing problem how to move about in the
solar system without consuming much rocket fuel. The electric sail was
invented in Finland in 2006 as a byproduct of basic research of space
plasma physics, and is now being pursued by an international team
consisting of different groups mainly in Europe.
The electric sail consists of

A dual power source sectional wind turbine tower.
A multi sectional dual power producing wind turbine tower, that has a singular shaft section that is engaged by ratchet mechanism from the turbine sections to drive the generator, where one or more turbines can be turning dependant upon the height of the airflow stream, thus ensuring the slighter breeze power production is not lost as would be the case with a large single tower having to turn

I invented a VAWT (Vertical Axis Wind Turbine) design that needs a lot of work but it appears to be a good basic concept for mechanically controlling moving blades. The thing that appeals to me about VAWTs is that they only need a support structure 1/2 as tall and overall they are 2/5 as tall to be expose to an equal amount of effective wind area. I believe they can be cost effective because they
