Re: [PSUBS-MAILIST] Hydrogen Fuel Cells coming closer for Psubs?

[Jeff Post <jeffpost@rawbw.com>]

I'll try to be gentle here, but you must realize that this is nonsense. You do
not use electricity (what, from batteries?)  to crack water, to supply a fuel
cell, to make electricity!!

A much better idea would be a "rechargable" sub. When on the surface, you could
use a generator to electrolize water, and store the gasses for later use while
underwater. Although this is a better idea, it is still rather impractical for
most PSUB's (Casten excepted!).
