To answer your question, yes it is possible. However the main problem here is that the electricity producing generator (off of a gasoline driven engine) is probably made to turn at an extremely high RPM. These RPMs are not feasible for a wind turbine to safely operate at. Not to mention at the diameter you will need to match your power output. So to solve this problem you could devise a clever gearing system, however that would take probably more work than building an alternator that is more fitting for low RPM operation.

It's possible, but probably not practical. Like Prfesser said, the windmill would have to be HUGE and mounted quite high off the ground, which would necessitate a large and very strong mast with a rotating top (to keep the windmill facing the direction of the wind. On top of that you'll need a differential gear (and a way to regulate it) to keep the shaft speed of the generator constant.

If you're asking if a windmill can put out 1800 watts from a suitable generator, yes, it's possible...

It's going to be a pretty big job. The wind must provide enough oomph to turn the generator. That kind of windmill is not small. http://www.otherpower.com/otherpower_wind.shtml indicates that a 1000-W windmill needs to be about 10 ft in diameter. Presumably an 1800-W device would be roughly 15 feet in diameter. And for reasonable efficiency the device will need to be mounted way up in the air--40-50 feet or so.

If you already have the generator, you'll need to gear it such that the wind turns the generator at the proper speed.

Good luck.

Ummm...not sure what you mean? A windmill that puts out electricity is a generator; it doesn't "power" one.

Are you asking how to attach propeller-like blades to a generator motor so that it can be turned using the wind, rather than a gasoline or diesel engine?
