GM:

According to my calculations, your assumption is wrong. I calculate (and

I

await verification) that 10 sq miles is about 26 million meters. The

direct

sunlight is 1370 W/m^2, but that is only with the sun directly overhead.

One can expect half of the time, it is dark and one will get on averages

somewhere between 25-35% total insulation (I haven't actually calculated

this but it isn't hard to do) but that means that each meter of solar

cells

floating on the ocean will recieve a daily average of 479 Watts. But

solar

cells are only 20% efficient so that reduces each meter to 96 Watts per

meter squared. Rounding up that is about 2500 megawatts per day from the

10

sq miles. California uses baseline around 10000 megawatts; peak demand

is

36,000 megawatts. Unless I have missed something (which is always a

possibility) I doubt that 10 sq miles will supply California.

AK:

Since this report was considering tidal or wave power, I am thinking

that the 10 sq mile is more like a 1000 mile long ribbon just offshore

that is 52.8 ft wide. Can one put tidal or wave power equipment

positioned in many rows back to back?
