It has actually been better put across by William Mook (aka
Mokenergy), and the mainstream status-quo of forever hydrocarbons
hasn't bought into any of it.

Yes, H2 can become relatively cheap, though perhaps not ever as cheap
as offered by William Mook, and otherwise it's ideally suited for fuel-
cell applications, as well as for dozens of applications in
commercial, industrial and retail/end-use.

Supposedly the Boeing solar panel division (Spectrolab) has actually
broken the 100% PV efficiency by converting IR through UV, although
that's with a rather spendy advanced product that most of us can't
possibly afford.  Commercially and otherwise for space or military
applications they currently offer a spendy 43% efficiency factor.
