Let me weigh in on the side of the junk science.
*IF* the method allows efficient reaction of the Aluminum wire with 
the water, and that is something I don't know, but which others 
probably do, then the claims made on that page seem modest.
E&OE as ever, but a quick run through Excel suggests he should get 
about 9 litres of Hydrogen per minute from total reaction of 180 cm of 
1.6mm dia Al wire.
And that should have an energy content of about 1.7 kW.minute
ie produce a power of 1.7 kW for 1 minute at 100% efficient conversion 
of the H2.

I may have dropped a few powers of 10 somewhere.
I used an SG of 2 for Al. (2.6?)
I used 36 kWh/kg as energy content of Hydrogen (about right).

Super rough spreadsheet here

I'm happy to discuss this further and by all means point out where 
I've dropped a few powers of 10.

Assuming I haven't, the key question is, does the actual method of 
getting Al to react work?
The energy efficiency of the overall process is not in question - it's 
low compared to sucking oil out of somebody else's backyard and 
selling it at rates that don't reflect the long term value. But it 
could still be a useful process for some things. And I'd expect it to 
power a VERY large cigarette lighter, if it worked at all :-)

(1.6/2)^2 x 3.14 /100*180 = 3.6 cc Al/min
At 11% H2/Al by mass and Sg Al = 2 = 0.8 gram H2.
0.8/1000 * 36 = 0.03 kWh
.03 x 60 = 1.8 kW for one minute
!

.8g H2 = .4 Mol
22.4 x 0.4 =~ 9 litre/min H2 !
