Re: Worlds First portable Hydrogen Fuel Cell Launched (Uncle Al)
Hydrogen gas is relatively stable as a hydride or solid metal, you only need to convert it to gas as you use it. Safety standards (at least in the US) are based on enclosed-area measurements anyway so just ventilate properly and you'll be ok, no boom.
The energy density of liquid hydrogen is roughly 55% that of gasoline when measured in kW-hr/l. It is less efficient only because of the way fuel cells convert it to energy, a process involving fusion would yield an entirely different ratio ('psi' is not a unit of volume, by the way.)
As with everything, it all comes down to cost right now because necessity hasn't set in, as yet. At some point in the future it will become cheaper to use alternate fuels when determing costs across political boundaries, health factors, environmental pressure, etc. This won't likely be any time soon so in the mean time you go right on using hyperbole to dismiss it, and of course stay close to your precious flush toilets.
