what would be the hypothesis of the air battery/saltwar battery?

Answer 1

well an air battary was almost invented already. Ever heard of an air gun. you get an air compresser and anything you hook up to it, it can run. ex. air drill (mechanics use this). I am sure there are ways to further this invention to be compatable w/ ex radios or electronic devices. Same with a salt water battary. salt water, however would be less powerful because it is more dense that both air and fresh water, there for cannot hold as much pressure as air. Air would have more power and last longer than salt water.
