Comment on How much power can a 1kW wind turbine produce for your home? - Engadget
HerbGrower@slrpnk.net 7 hours agoI see them from time to time, usually on sailing boats or coastal beach cabins where I presume they can slowly charge a battery over a long time with probably not much power production.

On sailboats? Huh. I was just looking into converting to electric, a lot of them do regenerative charging through the prop.

Yeah, not sure what it powers. Maybe radio battery and if you are sailing you probably have wind at least.

I mean was it actually a windmill generator? I have windmill-looking things on my boat for measuring wind speed and such (they are small). It’s just that using the actual sails to pull your boat along, and then using the speed to turn a water turbine on the hull is way more efficient. Especially since there’s no meaningful difference between a motor and a generator, apart from which way the power flows.

Seen similar ones on holiday buildings along others with solar panels too though. Aren’t the windspeed ones much smaller? These were probably close to 1m diameter.
