As I have been wont to say in the past ...

Its fizzix ...

You can't win
You can't break even
You can't get out of the game

So do the best you can with what you have left.

In the end it's all cold grey sand at -273 on the big scale.

Work the energy equations to see why hydrogen power is foolish today.  Less
foolish than electric cars though.

Do the math. Understand energy transfer and losses then much becomes
clearer.    Like mudbugs the meat is in de tails.

For our forseeable future portable energy will be fossil fuel. We best
adjust the non portable requirements to match more closely those sources
that need not be portable so as to conserve those resources that are
portable.  Ever figger out how much eeelectric extension cord it takes to
drive to work.  And how you carry it and how you roll it up when you get
there.  Do the thermo numbers and the answer for now is long dead dinos and
various coal extracts.

Oh yeah and read the thingy about SUVs and the merkin mentality.
