 I used to be a subscriber to Scientific American.  I started
reading it in the late 70's.

I quit reading it when it became clear that changes in the
editorial staff had caused political causes and spin to
take precedence over science.

Yes, there is LOTS of energy, but anyone with an even
basic understanding of thermodynamics will tell you that
some forms of energy are less recoverable than others,
even assuming loss-less conversion.

The above list is political, not scientific.
