This is a salt-water battery that also generates hydrogen 
with no external power source as long as there is a load
across the terminals, at least that is what is claimed.
Patents are by a Francisco Pacheco. Following are the abstracts:
Patent No. US 5,089,107
Title: Bi-Polar Auto Electrolytic Hydrogen Generator
Abstract:
An autoelectrolytic hydrogen generator system constituted by one 
or a plurality of similar cells wherein a galvanic arrangement of 
magnesium and aluminum plates of sacrificial elements as anode; 
stainless steel as cathode and sea water as electrolyte, by its 
very nature is made to develop a voltage when connected in short 
circuit causing a current to flow within the system and hydrogen 
production of hydrogen in situ and on demand by the electrolytic 
action at one pole, the cathode, and additional hydrogen by the 
electrochemical reaction at the other pole, the anode. Surplus 
electric energy of the system applied to an optional electrolyzer 
will also be made to produce additional hydrogen at its two 
sacrificial aluminum electrodes.
The earlier one:
Patent No. US 3,892,653
Title: Hydrogen Generator
Abstract:
A hydrogen generator constituted by a voltaic cell having a 
reactive magnesium electrode and a non-reactive electrode 
immersed in a salt-water electrolytic bath, a load being 
connected between the electrodes to cause a current flow 
in the cell resulting in an electrochemical reaction in 
which the magnesium is decomposed to produce hydrogen and 
in electrolysis in which the water is decomposed to produce 
hydrogen. In order to minimize polarization and other factors 
which diminish the production of hydrogen, the solution is 
circulated through an external flow loop having a pump 
interposed therein to draw the electrolyte from the bottom 
of the bath and to return it to the top thereof, the pump 
being powered by voltage derived from the cell.
This guy supposedly ran both cars and boats off of the hydrogen
these units generated on water alone. It seems like a excellent
solution if it actually works.
