Mag Wind Turbine

So everyone knows... This turbine is a drag-based vertical axis wind generator. At best it will be 50% as efficient per unit of cross-sectional area as a more traditional horizontal axis turbine (like one from Southwest Windpower, Vestas, Siemens, GE, etc.).

I add the caveat "at best" because these wind turbines would likely be put on rooftops, or areas where the wind flow is severely disrupted by ground objects (as opposed to a turbine mounted on a tower). Better to not waste the metal.

The last question has to do with the fact that mechanical losses are the minor consideration in wind turbine design after placing your turbine in reach of the best resource (usually height or general location) and optimizing the coefficient of performance of the turbine itself, which is the % of energy that you can actually extract from a given wind. Given the geometry and diameter of the electrical portion of the wind turbine I imagine that you have (size relative) elevated electrical losses.

Better to compare your product to the competition that already exists. Several obvious problems: 1) Wind is naturally going to be slower at the level of a rooftop as a result of atmospheric conditions (boundary layer friction). How is this better than a 12-25m mast on a rooftop? 2) Interesting to use the rooftop as a wind collector to direct flow. Nonetheless, what is the performance like when wind is from the other direction? 3) What is the C(p) of the turbine over its cross-sectional eq?

What is the performance like when wind is from the other direction? Do you not see this thing is alike from all angles? The wind direction does not matter with VAWTs.

A VAWT in general is the same from all directions. A VAWT installed on a rooftop is NOT the same from all directions. When the wind blows perpendicular to the roof the air should accelerate at the apex of the roof; this is the primary benefit of this otherwise inefficient wind turbine - you are artificially increasing the "effective" cross-sectional area of the turbine by placing it in an area where the wind reasource is greater. ..so my question stands.

i dont think that will work in the south with Hurricanes..

BRAVO!!!!! Bless our world!!! Bless our way of life.

WOW COOL.

Better than that Maglev one.
