The problem is that the air compression operation is only about 25% efficient and the air motors are only about 80% efficient.

A lot of electricity for not much motion.

Compressed air vehicles are used where fire safety is at a premium. The US Navy operates a compressed-air locomotive at its ammunition storage depot at Pearl Harbor.

Compressed air stuff has been around since the 1870s and is well-developed. Does it ever occur that if this refined technology made the least bit of sense for transportation, it would have been adopted long ago? Is everybody's brain so corroded by conspiracy theories?
