Very few things impress me as much as this did. It has taken a clever idea to the next level of simplicity. I was expecting something similar to the one AvE took apart, but this one is completely different.
I'm not sure if the cells are custom made or if they are standard zinc air cells, but the way they've been used is extraordinary. Do standard zinc air cells liberate gas when discharged slowly without a ready source of oxygen?
New Holland made many different models of square balers through the 1960's, and they all had similar components. In fact, modern square balers share many of the same general components. Using my New Holland 269 square baler as an example, I explain how the baler works, from incoming power through the PTO all the way to throwing a completed bale into the wagon, including the operation of the knotters. I also give maintenance tips and how to adjust the baler to make good bales.

When I toured that off-grid house in college, they had a microhydro system that was pretty neat. Microhydro is fantastic if you have water on your land, because water power is constant and is very energy dense. Even a fairly small stream with a decent head can produce quite a bit of energy.
I chisel plow the manure that we spread so it breaks down faster! By incorporating the manure, you'll lose less Nitrogen to volatization.
Frequency regulation on the grid is a big thing.
