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.

Well, they said two or three plus solar cells. Didn't mention batteries for some reason. Even if I assume that everything the said is accurate, and that two or three plus solar cells (how many?) would generate enough energy, there's no mention of how you deal with when the sun's not shining AND the wind's not blowing.
So, yes, it's marketdroid speak. Any engineer would have known that it was misleading no matter HOW poor an engineer he was. Either that, or it's an incredibly bad translation that just happened to be grammatical.
