Global warming?

[ZenGum]

Thanks, TW, but there was some strange stuff there (even by your standards).

Hydrogen (ie water) has no energy...

ie = id est, that is. Hydrogen is not water, we both know that.
Your point in much of your post seemed to be that hydrogen is a storage medium for energy. So what?
Call it a storage medium or a synthetic fuel, that is just semantics. For that matter, we could say that coal and gasoline are just storage media for the energy from sunlight that hit earth 100 million years ago, and uranium is a storage medium for the energy from a supernova 6 to 10 billion years ago. There is a difference, in that with hydrogen, we put the energy in there deliberately, but with the others it was there already, but ... so what?
A tank of hydrogen does not slowly lose energy the way a battery does sitting in the draw. You made some comment about losing energy due to thermodynamics, can you expand on that?
