We will never get there unless we start. How much did the first
heart transplant cost, and how well did it work compared to ones
done today?
Hmm. Has anyone started on a "brain transplant?" There are some
things that just cannot be done.
So there are currently no working photo voltaic solar panels? It can't
be done? Is that your argument?
No. My argument is "it is impossible to run this country/state/city off of
sunbeams."
The total radiation falling on the surface of the earth is about 1,300W/m^2.
At 23 degrees of latitude. At noon. With no clouds. Adjusting for latitude,
clouds, hours of darkness, and assuming 50% efficiency, it would take a
solar collector farm the size of the Los Angeles basin (1200 sq mi) to
provide for the power needs of just California (~50GW).
Imagine the cost, time to construct, and maintenance of a mechanical
apparatus 35 miles on a side. Heck, that's bigger than the pyramids!
