I work for a large company (>50,000 employees). IT recently rolled out a new "video delivery service." The system delivers videos to everyone's desktop. The system is designed by Kontiki. It's basically an enterprise BitTorrent tool which Kontiki prefers to call, "peer-assisted."

Efficient in terms of energy produced versus energy available. Not energy into the generator versus energy out.

With current windmill designs the windmill is not generating electricity in very high and very low wind conditions. Currently, windmills run only in medium wind conditions. Other times the windmill could be in a brake position to protect it. With the invent of this new generator, the windmill can produce energy at lower wind speeds and the medium wind speeds.
