Transmitting energy via compressed air has been around for at least 125 years. Do you not think that if it did not have show-stopper, it would have taken over in that time. Are 125 years of engineers morons? Do you think compressed air was squelched by some sort of oil company conspiracy?

No. There is a show-stopper.

Air compressors are ony about 25% efficient. The rest gets thrown away as low-grade (unusable) heat.

Compressed air power is OK where you do not want a build up of heat, like industrial tools or in an explosive environment.
