- Yes but they do so with a large AC line-powered compressor plus a large
- storage tank (a "battery", if you will), and the things that are powered
- are relatively small.

- An air tank big enough to replace the gas tank in even a lightweight car
- would be much bigger than the car. Fittings and so on to handle that much
- pressure would be "interesting". Especially the non-permanent connection to
- the air pump at the "recharging" station.

- Actually this is an advantage. First of all by doing all the "burning" in one
- place, you can realize economies of scale. Second, it will generally be
- cheaper and easier to install one really good pollutant filter on the power
- station's stack than to put little ones in all the cars.
