Three things I see this article doesn't mention:

1. What is the energy in to usable fuel energy out ratio for this process? How does it compare plain old hydrogen from electrolysis?
2. What is the volumetric energy density of the hydrogen generating zinc + water fuel? How does it compare to plain old liquefied hydrogen?
3. What is the potential energy output of this process?

Granted, I could pull out my CRC and do the math to answer some of these questions, but I'm feeling lazy right now. However, the fact that these basic questions are not addressed in this article raises some warning flags.

Don't you have a tungsten cowhide turbo encabulator handy to do the work for you? ; )

Metal ores require mining operations.
Charcoal requires logging operations.
Both of these operations require fuel.
