I've always been interested in wind power. Had several different turbines but never a vertical axis always horizontal. Might be worth a try but I think if they are too cheap you may come up against a fundamental flaw in terms of build quality. If you can design this out by modification then it could be okay I suppose. The cheap horizontal axis wind turbines do seem to suffer from some serious quality issues. I've got a second hand Aero6gen turbine I have not yet installed. Cheap eBay deal last year. They are ace. Made in england amazing build quality but no longer produced sadly. Real good piece of gear. I need to replace the yaw axis bearing as its wobbly. I ran one of these (aerogen 6) for a couple of years in the early 00s and it was remarkably effective but to be fair that was down the K&A where it is quite breezy. If you do go for one of the vertical ones u?I'd be interested to know how it works out  Not averse to having more than one wind unit on the boat ! |

I met someone with a couple of vertical ones this year. The straight bladed ones, the build quality looked good. He said there's less vibration and noise. His where on short masts as well so easy to put up take down. I was posting to see if anybody knew if they are any good. I'm sure the ratings are exaggerated but they are so cheap if they where half of the rated watts they would be good.

Interesting, however a quick google found what looks very similar (size, design etc) and it was rated at 400W in a 27mph wind, with very little at wind speeds below about 6mph. So where I moor, most of the time there is a bit more of a breeze, but unfortunately it’s only a few mph, so I suspect I would not get much power.

I bought an AirX 400 cheap from a neighbour, not tried it on the boat yet, but VAWTs are probably better. Afaik the air x needs higher wind speeds, though I believe there is a kit to convert it to an Air x Breeze, for power at lower wind speed.

It's that thing though of extra power in the winter even if you could get a regular 50w out of one it would be valuable extra this time of year. These Chinese ones are getting cheap enough to have ago at. It won't be this year though. |

Looks like something you would use to knock up the muck for the Brickies!! |

That’s very true, even if you could get an average of say 2 amps output on a typical day then over 24hrs that’s about 50Ahrs, which would certainly keep the lights on and water pumps running, though like solar there will be days of nothing. |

I don't think there is enough wind available onshore at the moment. Unfortunately most of the wind farms coming on line tend to be offshore. Perhaps once they start to farm onshore wind we'll see more availability.
