I was thinking you could make an air compressor out of something like this but you’d still have to cool it so you’re talking about a little electric water pump a little cooling radiator and you still somehow have to lubricate the Piston walls and the journals/bearings.. so you’re talking about some sort of oil misting device at the intake port for all 6 cylinders which is therefore going to get into the air that you’re compressing… Not a huge deal because you could make some sort of a catch reservoir in your air compression tank…Â People add oil to their air compressor lines to lubricate air tools anyway (sometimes.)
Still an interesting idea though.
