Looks like some engineering students are really getting serious about
hydro-cell technology for marine propulsion. Looks like it could
evolve into a a great alternate to fossil fuel and high dock prices.

I wish 'em success!


Why is this better than the "diesel electrics" I've heard about? You have
to
regen the engergy somehow. I'm also not sure it's as clean as they youtube
claimed. You have to make the battery. Of course, it's a step in the right
direction.

"This time, however, instead of belching smoke and fire, the
cutting-edge power source behind this voyage will produce nothing but
water vapor, as the New Cleremont is powered by two specially adapted
electric trolling motors connected to a couple of 2.2 kilowatt
hydrogen fuel cells."

'Nothing but water vapor' seems to say it all. Yes, the battery had to
be produced, but your 'diesel electric' had to be produced *and* it's
a polluter.

It's an electrical engine that has a diesel as a backup source to repower
the battery. The engine isn't any more polluting than any other engine.
