Fascinating concept.
I've seen this done by a Dutch company as well. The name escapes me for the moment. Trouble was (for North Americans at any rate) that it was 230V/50Hz. Both wind and water would need in-line gearing to match the high design speed of the generator. Otherwise it would need a complete redesign to slow it down. Wonder what the efficency is? The web-site does not have that info...
