then again, if you had a gate opener at the end of 2 mile driveway
that is battery powered and no handy power line, it might be just
the thing to get to keep a small battery charged.

Absolutely correct. There is a definite niche for solar power, or
wind power, or for bicycle operated generators. Any place one needs
a continuously availble source of a small amount of power, solar will
do nicely.... usually.... except maybe in things like coal mines

However, if the purpose is to "get off the grid" and "replentish
the
earth" or some such, the operator needs to make a business decision
regarding costs, maintenance, reliability..... and solar isn't even
in the running to replace an existing grid source...... the ONE
exception
being on government buildings where taxpayer money is used to set
up a million dollar installation where the maintenance cost exceeds
the
electric bill.... Since the taxpayers are paying for it, and the
politician
can get a few votes from avid tree-huggers, it is cost effective...

You make a couple of good points.

In addition is is not within the boundaries of physics to run this country
off of sunbeams, yet we keep pouring (government) money into the quest for
perpetual motion, er..., Sasquatch, er..., ah, I've got it, "Solar Power."

The ONLY way it would be POSSIBLE to run a city or a state off of sunbeams
is to move the orbit of the earth closer to the sun.
