A glycol chiller is the right solution if you're using a long-draw system - meaning you would like to have your chiller several feet away from where you plan to dispense. This system implements the power of glycol to move beer further distances, while still keeping it cold from keg to tap. Propylene glycol is combined with water to create a chilled mixture that's pumped from the glycol power pack through the cooling lines that run parallel to your beer lines. Propylene glycol, a non-toxic, food-grade antifreeze, is the main component that's been used for many years in food-processing systems. Glycol cooled draft beer dispensing systems are typically used in commercial applications such as bars, restaurants, and stadiums.
So there it is, all finished up! I took it for a test drive in the model A Ford. I didn't want to break it, so I never took it over 25 miles per hour, but it seems to perform well (considering). In a 25 mph wind it produces about 60 watts (5 amps into a 12 volt battery), so I think I can give it an optimistic rating of 100 watts...not bad for a 1 day project made entirely of wood. Obviously, it's not made to hold up over the long term, it was merely a fun little test, but I think the alternator provides some interesting data. I feel pretty sure now that with little work one could definitely build a very useful alternator completely from scratch. By simply increasing the diameter some one could get a LOT more output from a very similar machine. Of course, using better bearings would be wise, but I like the use of wood, because it is a material which is widely available, and easily worked with the simplest of tools. Thanks for dropping in and letting me show off this silly windmill!
