Pretty much what the headline asks, any one with input? I'm looking at one that claims 4,000 watts with a 22 MPH wind.
Sounds nice to have, but when you´re aboard you don´t even want them on a boat near you... To get an idea what I´m talking about take your vaccum cleaner, switch it on at low power and put it in the next room with the doors open. That compares to the noise level of a rather quiet wind generator with a useable bit of wind outside. Even if you´re really stubborn about it I´d guess you certainly don´t want to listen to it for hours, let alone days... But if you´re out a lot in rather remote areas you might even think about living with it rather than running the diesel powered radaddel machine.
