5. How much energy do you "think" is in moonlight?

How much energy do you "think" is in moonlight?

I can tell you - a trivial amount.

No matter how efficient your solar collector is, or how advance; it simply can not harvest energy that is not there.

No matter how advanced the solar collector; it can't violate the laws of physics.

So you can't have a trillionth of a watt of moonlight hitting your advanced solar collector, and have it produce 5 watts of power. It just plain can't happen; because it is a violation of physical law.

The moon sends a trillionth of a watt to your collector and 5 watts came out? Where did that energy come from? ( And please don't get confused about energy per unit area; like the people that "think" you get more energy from sunlight due to the action of a magnifying glass. Such people missed elementary school science where they explain the difference between "intensive" and "extensive" quantities )

The design may look futuristic to scientific neophytes; but to a scientist, it's nothing special.
