Plus, some guy, somewhere has designed the "helix wind generator" or something like that... I briefly saw it on the Green channel...
Basically, it's like the old lucky strike cigarette advertisement... it's a sign that can get wind current from any direction, and spin. This is great in like... Detroit, where wind can come from anywhere.
It can also take very light winds, and still be useful, meaning that it's more efficient than a standard wind turbine. It's designed to be used on rooftops and such in areas where it's not prudent to use standard wind technologies.
