"There are many advantages to using compressed air as the energy means to operate machinery; air is plentiful and renewable. The AOE system uses no fluids, doesn't draw water into the system which affects micro-organisms nor does it use submerged turbines that can kill marine life. Manufacturing and transporting compressed air has some unique advantages, "compressed air has little weight," explained Jim Matei, "so a 10 gallon tank full of compressed air weighs only marginally more than the same tank empty. Furthermore any leak is totally benign."
