Are air powered buses next?

[zubzub]

made sense 'til the end when the narrator got all " the compressor on board compressing air for the car"....that was stupid...if the tanks can hold the pressure and the air can be compressed at a reasonable expense...seems to make sense.  the idea of plugging in the engine to compress air is actually quite good...may be able to be used for regenerative braking as well....anyhow clean energy storage systems will be the future for small vehicles....'tis true would make a good toad.
