Anyone tried a Windmill for power?

I saw this RV size windmill charger the other day and it looks like a potential solution/addition (to solar) for charging batteries while off the grid:

It has two different mounting capabilities, one for the ladder or the roof rack of an RV. I would think the roof rack of the tow vehicle could be used for an egg-style trailer like Escape since they do not have a ladder. Or maybe something could be rigged off the hitch. Like a pole that could be slipped on when at the site.

The advantage over solar is that this windmill could potentially charge over night or during cloudy, rainy skies. It does have limitations on winds > 35 MPH (you have to take it down) but it is an interesting idea.

I have looked at them from other manufactures before. Not a bad idea if you camp where you get enough wind to power them. We look for spots out of the wind for the most part.

Even though they don't have a mounting solution other than rails, no doubt you could hook it up in some way to work.

I wonder how tough they are, and how much you would have to worry about damaging them during transport.

I also wish they had more info on charge rates at different wind speeds.

All in all, a great idea though. Any idea that can keep those batteries from draining can only be good.

Living up north a number of years ago I looked into alternative power sources. We did have power so I never got past the research stage but some people without power did have wind generators. On the down side a higher consistent wind speed is required to get anywhere near the rated output and for the blade diameter you the power generated will be quite small. Them going over their rated RPM in a storm and self destructing is another issue. On the plus side apart from the initial cost you got "free" power with minimal maintenance.

The design shown in the picture is a lower speed unit so it is safer in a gust (likely no flying blades in a strong gust) and will begin to generate some power at a low wind speed. If you like to camp where there is a steady wind and choose a unit that has the desired output at that wind speed it could be a viable option.

I would be really skeptical but my knowledge is mostly about the huge ones. A lot of times the wind speed 200 feet above is fine but on the ground it is minimal or too intermittent to be much use. We tent camped in the midwest where the winds were constant so maybe there it would work. In general I bet it's not worth while taking it along however I'd like to be proven wrong.

Windmills aren't silent either, if a humming noise bothers you. I also wouldn't consider mounting to the trailer. If there's vibration, that would drive me nutz. YMMV

Most of what I would say has already been posted - lots of good points. One more issue: anywhere with other people (e.g. a campground), other people will likely have small-scale versions of the same concerns faced by large wind turbines... such as noise, appearance, risk to birds, and even safety.

I like wind power, but site selection is important in wind power; that seems incompatible with the inherent mobility of a travel trailer.

I see it as just one more thing to pack around and mess with. Why do that? If you are going to enjoy the great outdoors, keep it simple. The solar system that Escape installs has proven to be the best method of dry camping off the grid with conservation in practice. Live aboard vagabonds that sail the seven seas mount them on large sailboats and cats. But that's just part of life support.
