Running on thick air
An engineer has promised that within a year he will start selling a car that runs on compressed air, producing no emissions at all in town.
The OneCAT will be a five-seater with a glass fibre body, weighing just 350kg and could cost just over £2,500. Its engine is less than a quarter the size of an equivalent diesel motor.
Driven by compressed air stored in carbon-fibre tanks built into the chassis, it can be re-filled with air from a compressor in just three minutes - much quicker than a battery car. Alternatively, it can be plugged into the mains for four hours and an on-board compressor will do the job.
The designers say on long journeys the car will do the equivalent of 120mpg.
In town, running on air, it will be cheaper than that.
Another eco-friendly feature is that when driven this car will be pollution-free!
This design is an intelligent step toward energy-saving transportation. It may also urge the big manufacturers to set economy and ecological targets.
