- Any wind electric turbine, as long as it is off the ground, can generate electricity. So the phrase "doesn't have to be very high up" doesn't mean too much, except that the rotor needs to be small enough to clear the ground.

- Next, any wind turbine is going to generate more power the further off the ground it is, in most wind regimes. So they're all going to need some kind of tower. Ideally, I think you would be looking for something that comes with a sectional tower.

- Yes, there are such machines. They are made in China and used in Inner Mongolia (maybe Mongolia as well) by nomads. I would guess they are simple, cheap, and not terribly reliable. No need to be too skeptical, though, this is definitely a workable application and one that is in use.

- There are some units made by members of the American Wind Energy Association (AWEA) that would be suitable for this application. Bergey Windpower Co. has an 850-watt unit (rotor diameter 2.4 m) that lists for $1995, and World Power Technologies has a 600-watt unit (2.1 m) for $980 and a 500-watt unit (1.5 m) (newly introduced) for $790. For further info on tower options, you should contact them directly.
