Right now, if you go into a gas station to fuel up your vehicle, you may find an air pump for filling your tires. In the near future the compressed air pumps may fuel our vehicles. A motorcycle with a current-generation compressed air tank can go for about 30km, nearly two-thirds of a typical day’s commute in the US. That completely eliminates lots of ground-level pollution, and the air could easily be compressed using renewable power sources. The same thing goes for cars.
