Helix Wind Turbine

The Helix Wind Turbine can generate more power with lower wind speeds.
Peninsular India is supposed to have generally lower windspeeds than northern India, and so perhaps turbines like this would be particularly beneficial there.

It has a power rating of 2 kilowatts, which is quite significant. It's also claimed to be less harmful to birds. If you visit the Helix website, you'll see they have a 5kW model, too.
Why can't Indians economically manufacture things like this, instead of cursing the power utility half the day?

The thing seems to have quite a lot of surface area on it, too. I wonder if that surface area could be further used to collect solar power? Just a thought.
