Nah.  Air compressors work with electricity so all that will be needed is a battery to run the compressor motor in order to recharge the tank.  There will be a need for some lubricating oil in the compressor motor as it has moving parts but that's it.

My feeling is that you'll get more power (torque) from a pneumatic-compressor driven system than a pure electric system - though they have improved the latter recently.  We'll see.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
