More Juice

It's hard keeping up with our power needs...electrical that is. There is a little bug in my system, for some reason my battery charger won't charge at full speed while we are away from the dock, using the generator. What this means is that I have to run my generator somewhere between 3 and 4 hours a day to charge the batteries. In a classic domino effect my refrigerators don't cool down all the way...because of the batteries being low.
So, how to solve this problem? I have 4 solar panels, and no room for any more, so I turn to the wind. Perhaps a wind generator can pick up the slack. A quick look-see on the internet had me gasping for breath. What! 2500 dollars!
Okay, let me let you in on one of my biggest vices, I think I can do "anything". Oh, it's a vice alright. In my defense, I inherited this genetic glitch. Awareness is half the battle, I try to fight it, but when I get hit with something like $2500 for $300 worth of parts, well, I lose control. My vice is at the wheel, yet better than younger days when other parts of me ruled over my common sense!
I started searching the internet for the parts it would take to assemble a wind generator of my own. I'm looking at about $400 bucks for a nice size unit, 600 watts in 25 knots of wind, and 100 amps in 12 my estimates. This should give me about 100 amps on a typical Caribbean day, which my refrigerators would just love to eat up.
The tricky part is balancing all the parts, the size of the motor with the size of the blades, and the size of the tail, and a half dozen other components. Oh, and making it not look homemade is important to me. Getting materials here in Puerto Rico has proved a challenge. After a tank of gas, and a day of running around with no luck, I just gave in to the convenience of Amazon.
Here are the blades, the motor, and nose cone.

This is the mount which I'm in the middle of fabricating.
I'll keep you up-to-date on the progress, but right now I've got to take advantage of a great weather window to sail to St. Thomas. See you soon!
