It was almost fun wasting my time on this one.

7 amps at 12 volts is 84 watts, or 0.11 HP or electrical energy being 
consumed by the "brick".  That electrical energy is splitting 
hydrogen and oxygen from water.  When the Hydrogen and Oxygen are 
recombined by burning you get back 0.11 HP worth of heat (assuming 
100% reversible conversion efficiency).

If the alternator is 80% efficient it is consuming 0.14 HP from the 
V-belt drive.  If the engine is 25% efficient it might produce 0.03 
HP from the hydrogen gas.  Net energy conversion efficiency is 20%, 
or 80% loss of energy in the process.  The net energy output from the 
hydrogen might just about run the auxillury water pump, so the 
increased load on the alternator is a total loss.

Does it not seem funny to anyone else that the engine in the video 
was consuming more than 2 gallons of fuel per hour when idling, at 
the same time it was blowing black soot out the tail pipe?  A stock 
MG will consume about that much fuel at a steady 60 mph cruise speed 
around 3500 rpm.  I suggest the first test was done on full choke, 
while the second test was done without choke after the engine warmed up.

No cigar for that bloke.
