The Air Car

The Air Car - zero pollution and very low running costs

Pros
- no pollution - operates on compressed air
- 1/10 the cost to operate of a gasoline car
- oil change > 1 litre of vegetable oil for every 50,000 km.

Cons
- top speed of 68 mph
- needs compressed air stations/compressors
- small production means not readily available
- to compress the air, energy is needed, so there is some pollution from whatever the electricity generation gives off

... unless of course the compressed air is produced with compressed air (which is produced with compressed air, which is...)
