I took this video a few nights back - what a fascinating contraption! https://www.youtube.com/paulwheaton12#p/u/0/GsDyp9gf17s
We milked goats for years , that stupid thing would be too slow and take more energy than hand milking .
Looks to me like one of those "Wow, this is great!" things that ends up in the pile behind the door. My first thought was "I can milk at least four times as fast as that - too long on the return stroke"
