Cars powered by pressurized air was already invented why is that no attention has been given to it?

Question

I am wondering why the latest invention of cars run by pressurized air seems not to be gaining support. It is very cheap to maintain said cars. If the prices of oil products keep on increasing, why, this alternative is not given special attention?

Answer 1

cuz they are about as useless as a nun's ****, or **** on a bull!! too labour intensive to keep changing and refilling the overweight tanks, short range, and more green house gases arecreated burning coal to create electricity to power the air compressors to re-fill the tanks, as well as transporting the filled tanks and returning the empties to refill than is saved.for every mile you drvie the tanks have travelled 60!!!think abt that when you figure your going green! btw it takes 16 gallons of regular diesel to get 1 gallon of bio diesel to the consumer, still think your saving the enviroment?

Answer 2

1. high weight of air bottles

2. low capacity of air bottles (and therefor, short range)

3. long recharge time for air bottles or constant labor changing them

4. no market for them

1 and 2 could be solved with new materials (thick steel weighs a bloody ton). 3 would require massive infrastructure changes, but could be overcome (pull into a station, they switch in a full bottle, you drive away). 4, though, is the big problem. if people don't want it, nobody's going to make any
