Robot-Fish Psubs (was Re: Screw size and speed)

Hi all.
Dick, below are some sites you can refer to for your next
fish-like propelled Psub!

Some think the future of subs is here. Look: Phil's already built
a sub that swimms like a... Man! (Exosuit).
(BTW, Phil, can you really move your legs to the point it can be called 
'swimming' in the Exosuit?)
