I am looking at moving soon, and with that I will have a lot more room to brew. This leads me to thinking about building a brewing sculpture. I have kind of an odd thought though, I'm trying to make as eco-friendly a brewstand as possible.
To that end, I would like to use batteries to power my pumps (DC of course), grain mill (Drill motor, so also DC), etc. I would like to have a small solar panel and wind generator to recharge the batteries. I would really only need to run the pumps for transferring wort. The grain mill wouldn't run long either. I am thinking about using a couple of car batteries.
