Interesting page.

A minor nitpick:

You present the equation E = R x I x L x T

with T being the loss in transmission between the supply and demand.

I don't believe transmission loss is usually reversed to mean efficiency, so your formula would have the energy delivered increase as the transmission loss increases. Perhaps you mean:

E = R x I x L x (1.0-T)

or

E = R x I x L x F

Where F is the normalised efficiency of the transmission between the supply and demand.

Also, I assume you have allowed for the fact that more distant geostationary solar arrays spend less time in Earth's shadow so have more illumination per year.

Chinese Scientists Plan Solar Power Station In Space 226

knwny points out this lofty proposed power plan in China. "The battle to dispel smog, cut greenhouse gases and solve the energy crisis is moving to space. If news reports are to be believed, Chinese scientists are mulling the construction of a solar power station in a geosynchronous orbit 36,000 kilometres above ground. The electricity generated would be converted to microwaves or lasers and transmitted to a collector on Earth. If realized, it will surpass the scale of the Apollo project and the International Space Station and be the largest-ever space project."

Your position is idiotic for any functioning society.

This argument reduces to the assertion that any dress code is immoral, and that people should be able to wear anything they like, including nothing. You then use the absurd leap to liken such a society that has a dress code to an oppressive muslim regime.

I hope the next person who sits beside you on a bus thinks like you do.

GP is probably referring to the continuous spectrum of a black-body emitter.

Try putting a spectrometer (eg a CD) on an LED or CFL bulb and compare that with the spectrum of an incandescent. Now, that awful banding you see on the former applies to actual objects as well, which leads to things looking "unnatural".

That said, phosphors have improved a bit lately so the problem isn't quite as bad as it used to be.
