Hi, just found this sight, and have questions. I've been trying my hand at building a wind generator. I'm new to all of this, as you will probably be able to tell by some of the questions I ask. First, a little history about what I've done. I started out with a 40' tall, 3 leg Aeromotor windmill. I put one side of a 3/4 ton free floating pickup rearend in the top of the tower for the pivot. the free floater style has the hole through where the axle goes through the hub. I then took another car style rearend, made a cradle out of a 1 ton bud wheel. The whl. is welded to the car rearend so that the pinion points through the center of the wheel. The 8' aeromotor prop is mounted to the wheel flange on the car rearend. Then the whole assembly is bolted to the truck hub in the top of the tower with the truck wheel and lug bolts. This points the pinion down through the center of the tower. I then connected a shaft to the pinion flange, to drive an alternator mounted in the tower at the platform level of the tower. This setup drives the alt. 3 1/2 revolutions to 1 revolution of the prop. In looking on the internet, I decided not to use a delco alt.. I switched to a treadmill motor that I had. It is a 2 1/2 hp dc motor. I've got the tower all up with the motor mounted in it, but I'm still making the tail furling mechanizm, so I haven't put the drive assembly up yet. When I do, though, hopefully it will be generating from that time on. Sorry for going on and on. This is my first attempt, so I admit I know very little about any of this. Now to the questions. I was wondering if I can short the motor across to cause it to act as it's own braking system for extended lengths of time, say when a storm with high winds are coming, without damaging anything? This might be for days at a time. I live in NW Mo., where we get tornados once in a while. My main reason for starting this project was for decoration, then things started changing as it progressed. I plan to make a battery bank at the base of the tower to power a small water pump for circulating water from an old hand pump, to a cast iron tub/watertrough, and maybe some christmas lights on the tower. I also thought about running a line to the barn to hook up to my machinery as battery maintainers. My other question is, if it makes enough power, can I hook this type of a setup to the grid and maybe cut my electric bill down a little. I do plan on getting a controller and dump resisters, once I find out how much, if any juice this puts out. I'm sorry again for taking so long to get to the point. Thanks a lot for any info anyone has to share with me.
