Urban Wind Turbines

A Dutch company has launched a new type of wind turbine that is small enough to fit onto the roof of a house. The turbine looks like a Nautilus shell, and their website explains how it works:

Most today's wind turbines require that a difference in pressure between the front and the rear side of the rotor blades be maintained in order to be effective. However, this difference in pressure also has a negative effect called "drag".

Our turbine rotor captures the kinetic energy of the wind due to its speed, and, by reversing the wind and reducing it to almost zero Beaufort converts it into mechanical energy. By doing this the wind speed's effect (in kinetic energy) on the rotor is maximized and "lift" is obtained by the wind's acceleration over the rotor plane.

    I don't understand how you can have an airfoil that doesn't exhibit drag.

    Well, Stupid...

    You can't understand how their device works, because you missed where they explained that they developed and used alternative laws of physics to design it:

    [We] "developed new theories and techniques that more closely follow the natural laws of physics for energy."

    http://dearchimedes.com/who-we-are/ [dearchimedes.com]

    See!!! When you develop your own theories, that outperform everyone else's laws of physics, it's easy enough to build friction-less airfoils.

    Can't wait to see how they harness perpetual motion theory to make the world a better place.

      With perpetual power comes perpetual responsibility and nobody wants perpetual responsibility.

            Well, he has an "image," upon which humans are based. I would have to presume that "image" is some variation on the concept of a body of some sort.

      If we can turn human stupidity into an energy source, we'll be set for a very long time.

      They're going to strap magnets to the corpse of Sir Isaac Newton, and put a stator coil in his casket, so they can generate all the electricity they could ever need, from the process of him spinning in his grave.
