to go back to the original post:
"A motor by definition requires electricity and the magic of magnetics"
maybe 50GMC253 could clarify just which dictionary he uses? the one that doesn't consider pneumatic or hydraulic "motors" - and then he could elaborate on why so many [or few] insist that "engines" have to be thermal and "motors" have to be electric - and why he thinks magnetism is "magic"
