unfortunately solar will never be more than 5% or so of the power
grid, that is because its limitations, running only when the sun
shines. and cost approx 5x per killowate
Well.... never is a very long time.
I think in the future we will harvest all our energy from a star. The
question is can we make it to that stage
before killing ourselves?

a friend of mine, Dr Keith Henson is working on deep space mirrors
that can focus a hot beam to a ground target at very high
termperatures to generate steam and drive steam turbines.. lots of
issues with controlling mirrors that large,, (thin mylar films miles
across
that would work but it will be a while
meantime nuclear is here now, and the cheapest cleanest form of energy
except hydro electric in the world. hydro is about tapped out
among the more viable alternatives is tidal and wave energy... but
still just a trace of what the nation needs now and into the future
solar cells produce power but is difuse not cost effective....
parabolic solar reflectors in the desert though are already proven and
in use in israel and the western US desert ( forgot details) thats
viable...produces high pressure steam to drive turbines but still
cannot compete for cost and raw power with nuclear, coal or oil...
coal the dirtiest, nuclear the cleanist.
listening to the coal lobby is not the path to enlightenment... al
gore and family have been heavy into coal for half a century
in this mess its liberal arts majors led by the coal lobby pushing the
bad science... thats a majority.... engineers and physicists are less
than a 1 percent minority.... virtually all of us know better,

Years ago I worked with a person who put together a little bottle that
can be used to boil water
using the sun. The bottle was to be used in places in Africa where
water
had to be boiled to be made safe to drink. The bottle was actually a
box with copper tubing inside and the side that
faced the sun was made out of glass. The inside was painted black. It
took about 20 minutes of sunlight
to bring the water close to the boiling point of water. It was easy
and cheap to build. The only problem was getting
the right paint. Does not compare to what Dr Keith Henson is doing
but nevertheless interesting.
I remember years ago when the styrofoam lobby (self proclaimed
environmentalist ) pressured Mc. Donald's
and others to replace paper with styrofoam. They claimed that killing
trees for paper was bad for the environment.
I guess none of them bothered to became familiar with how styrofoam is
made and how long it takes to break down.
Needless to say it was not long before Mc. Donald's went back to
paper. I wonder how much damage to the enviroment
these "environmentalist" actually caused?
