Also interesting is hydraulic energy storage. Any entrepreneurs want to take a shot with this system? http://license.umn.edu/technologies/z07054_hydraulic-ener

  >Hydraulic energy storage systems store energy by compressing air similar to a battery storing energy in an electric circuit. Wait, did you read the article? :)

    Hydraulic systems and compressed air systems are usually regarded as separate things. Maybe the distinction is a bit arbitrary and the former can be regarded as a subset of the latter but there you go. edit: Google says hydraulic transmits power through fluid, compressed air through air/gas.

      Pneumatic vs hydraulic is about compressible vs incompressible fluids. (Naturally, hydraulic oil is also a much better lubricator and an exceedingly superior sealant than oiled air).
