Fair enough. Whatever sends that energy back to Earth can only be on one side of the moon but the solar receptors can be all the way around it.

@MeGrendel: True that! It would need regular adjusting.
Micro-meteors would be a problem too, but the same for both ideas: they hit the Moon just as often, eh? Perhaps more so.

Both systems would need "around the world" receivers to collect the energy too, obviously. The energy could be split into multiple beams and bounced off relay stations to cover the Earth evenly at any given moment.

It's fun to think about! Sci-Fi is cool.

5Cats-"Lagrange Point stations operate 24/7"

Taking into account the needed surface area and mass, an array would probably need to be a little deeper into the gravity well than the Lagrange point to offset Solar Pressure (think Solar Sail).

Runemang-"but "rotate" is about as accurate as saying Mt Everest rotates on it's axis"

The moon does indeed rotate on it`s axis. It rotates once per lunar orbit, thus presenting the same face toward Earth.

You need to take Earth`s persepective out of this. Use the perspective from Sol (the sun).

If the moon did not rotate, the same side would always present itself to Sol, (over a lunar cycle) but it does not. When you see a full moon, the Earth is between the moon and Sol. So the moon is presenting the same side to both.

BUT, during a new moon, the moon is BETWEEN the Earth and Sol...so one side is to the Earth and the Other is to Sol.

So from Sol`s persepective (and the rest of the universe`s), it does rotate.

If it DID NOT rotate on its axis, each Longitude on Earth would see a slightly different face.

@Squrlz4Sale: All valid points, but it's still "unworkable".
>Half the panels would produce no power at any given moment: just like on Earth!
>>Lagrange Point stations operate 24/7
>>There`s no orbital decay in a Lagrange Point! That`s the point of the points!
>3 meters wide and 10,000 kilometers long? That`s freaking HUGE!
A Lagrange solar panel would only need to be half that size for the same power output.
>>Robots work just fine in Zero G. Humans like some gravity though!

If needed? The robots could still build the panels on the Moon (out of "Moon materials") and send them into space... It`s really, er relatively, easy to launch stuff off the Moon, eh?

I also recall "Moon Dust" being a factor. A tiny coating of dust drops a panel`s output by a large amount!
