Why not build cars that uses air compressor?
Fast Fingers asked:
I am just wondering why that we have great engineers that came up with the air compressor to drive all the air tools, why can’t they just put the air compressor into driving cars? Besides, they can basically build a wind driven electric generator somewhere on the car to charge up what ever electrical sourse that will be use to pump up the air compressor…

In order to run a car with compressed air you would a pressure of the order of 4400 psi, and the power output is not nearly as great as that of an internal combustion engine. A hybrid is being developed though, c. air is pumped into the engine until the car reaches 40mph, then it uses air/fuel mixture for highway speeds.
First, an air compressor would be way too loud.
Secondly, wind is’nt enough to sustain a constant source of power to the compressor.
What happens when you are stuck in stand-still traffic on the freeway or on the street?
This is such a GREAT question. Why can’t we build a car that would run on something besides gas/oil? I’m not an engineer, so I can’t answer the question, but I sure wish we could find another way to not be so dependent on oil/gas (and not have to ride a bicycle in the rain/cold).
Mercedes Benz made a truck that runs on compressed air. I remember reading that in Motor Trend magazine. I can’t remember how many years ago I read that. It does exist, but the mileage you get is pretty bad before you have to re-fill with compressed air again.
Personally I prefer the Fred Flintstone lift and run system? LOL
Simple: Efficiency rules. Hydrocarbon fuel, even with all the losses is one of the most compact and efficient energy source that meets all the requirements for cars – including overall cost.
I don’t think it would be practical. But it is good that you are thinking outside of the box.
It’s not economically feasible or it would have been done. How about a gas (or diesel)/hydraulic hybrid? Hydraulic has no compression loss problems like air and has less heat loss than electric. Lots of industrial equipment already uses this method. Probably too expensive for cars.
I think the the law of diminishing returns would come into play.
I am impressed with the NEW UPS vehicle that uses compressed hydraulics to generate energy.
That has a cheap and functional way to add fuel savings to just about any vehicle.
You’re asking why we can’t make a device which produces it’s own energy. Search “Thermodynamics”.
