Cheap Wind Turbine
 
Just to be clear, I have a 22' boat that is more than adequately served by a 50 watt solar panel, I have no need for more electricity.

Nonetheless, I found myself idly browsing wind turbines. I came upon this one on Amazon:
Happybuy Wind Turbine Generator 500W DC 24V Wind Turbine 5 Blade

Yes, "Happybuy" brand so you know it must be good!

But seriously, how crappy is this thing likely to be? What's the difference between marine turbines and backyard ones like this?

You know, just in case I want to put an icemaker on my boat.

"HappyBuy" sounds a lot like what my 'Thai' massager says....

It looks very similar to my "SunForce" wind generator.are the idiots so stupid to know they should call it WindForce?

Anyway, it's been fine for 4 years or so.

At the price you will have a happy ending.

At that price, I'd wager you'd be the most hated person in any anchorage or marina within a year. We had a cheapie anchored near us (not quite next to us) a few days back and we could hardly converse without shouting in our own cockpit because that boat's windgen made such a racket. I don't know if it was the blades or bearings, but it was awful.
Occasionally, we get invited aboard a boat, and they must shut off the windgen so we can converse in the cockpit. I've met a few folks who have noisy windgens who joke that they can tell the wind speed from the noise their windgen makes and one woman who thought the racket her windgen made was really 'neat' because when it was making all that noise, it was producing green power. I gently reminded her that now, instead of emissions pollution, she was making noise pollution. She did not think that at all funny.
I spent the better part of 2 years checking out windgens before I dropped my dime. No way I wanted to be a noise polluter!
But do consider that a windgen will probably average something in the range of a quarter to a third of an amp per hour, overall. Not worth the investment or noise unless you really need a few extra amps of charging at night.

I've had a few gf's where a very loud wind generator has been a benifit.

Iirc, there are 3 or so really good ones now...d400, superwind and another...duh, forgot it.

But youre looking at a several $k
And it is another system to manage..in addition to your solar

Northern lats with big wind and little sun, sure, thats your trick

The third quiet one is Rutland. Actually, I have no knowledge of the superwind and how quiet or long lasting it is. The three I chose between was D-400, Rutland & Aerogen, after a lot of personal experience and research.
However, just out of curiosity, exactly how must one have to "manage" either of these systems? Both my windgen and solar systems have been in place and operating for YEARS and I have done absolutely no "management" of either. They have also been maintenance free, which is very nice.

If wind generators are loud because of the bearings, I can see how expensive ones could be better. However, if it is just the blades, why couldn't a cheapo just copy the blade profile of a quiet windgen?

Cheap equals cheap and you generally get what you pay for but if you add the saltwater environment to the equation, you end up paying a lot more for the cheap stuff.
I could have bought 4 AirX windgens for about what I paid for my Rutland, expecting to get perhaps a year of reliable service from the AirX. So that means every year someone has to go aloft to change it out, never mind storing one aboard in case it fails prematurely. It also means at least twice the shipping if you order two at a time. I certainly am not going to try to save some money up front, only have it cost me much more time, work and money, in the end.
Cheap units have inferior wiring, inferior parts and inferior coatings, not just poorly designed blades. A few get lucky, but most who go for the cheap windgens are not especially popular in the anchorages. So, I guess it is a case, once again, of 'Do I feel lucky?' Well do ya,....?'

Copy the su33 and they have the j15
Lets try this again with the su35 engines...and expect something different...:)
