If you've ever seen the movie "the hunt for red october" (tom clancy novel), it says how a submarine has a silent propulsion system. they explain it as a jet engine for water, but with no moving parts. i was just curious if this is even possible, and if it is, how it would work.
I've been looking at the site, and i like it, im only a jr. in high school, so i don't understand too much of the real technical stuff yet. but i think im leaning toward engineering for a career and all.
another quick question, how do nuclear reactors transmit energy from nuclear to mechanical? is it steam...can't remember for some reason right now.
wonder if zarkov has any crazy ideas on this one? hehe
