And great advance have been made in PV during those decades,
particularly since the 60s. However, it is the process of pursuing PV,
hydrogen and electrocatalytic solutions, that will ultimately save our
pathetic asses. Noboby in their right minds thinks that everything will
be switched over to PV - H2 anytime soon, but pursuing it, as if our
lives depend on it, which they do, will generate the technological
advances and evolutionary and revolutionary scientific results, that
will ultimately clarify the practical solutions to humanity's dire and
very real hydrocarbon combustion problem. PV -H2 is the goal that we
must strive for, not the end. When and if we ever do get there, I can
guarantee there will be some other nasty problem to deal with, that we
can't even imagine right now.
