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.
How much energy and from what source did the energy come from to get the
hydrogen into the fuel cells? It may be the future but it aint quite
there yet.

Diesel electric is still more cost effective.



Hydrogen is a scam, much like ethanol. Overall it is an energy loser.

Hybrid vehicles are a scam too. What is the "carbon foot print" of the
battery pack to produce and to recycle?
