We will never get there unless we start. How much did the first

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!



People that grow flowers and such have been using solar power for
hundreds of years. They are called greenhouses. They open and close
vents and shades to fine-tune the temp as needed. A lot of the same
principles can be applied to residences and commercial spaces, thereby
reducing the electric/gas/oil they need to get by.
