*60% efficient, Livermore [https://www.techbriefs.com/component/content/article/27739-harmonic-air-motor-offers-very-high-efficiency#:~:text=The%20Harmonic%20Air%20Motor%20developed,be%20manufactured%20at%20lower%20cost.]. Implies standard air motors are 10-20% efficient. But even with that - that is good.
