There are a number of these mechanical devices (even a form of steam engine) - look up Hero of Alexandria. They didn’t make the leap to using these machines in a mass-produced, industrial manner though; mainly just as curiosities. History would have turned out so differently had they been able to make the leap.

No real way around it - getting to Jupiter takes time (especially for a heavy orbiter that can’t just zip by like the Pioneers, Voyagers or New Horizons - in which case it takes about a year). The SLS can do it in 2 and change, but it isn’t available (or even tested), a good fit with the spacecraft and would cost a neat billion more than FH.
