Methods of compressing air at over 100% efficiency are possible using a temperature differential and the ocean.
But unless we are compressing CO2 exhaust from a power plant what’s the point of a gigantic underwater air column?
And if we did
why waste it in an inefficient air motor that has just as limited of a range as a Hydrogen or Early BEV vehicle?
Compressed CO2 would have more value in industry than blowing a car.
The only advantage of an air car is free air conditioning, maybe nice in Solcal but not fun up north.
