Can't remember last time i saw a bunch of barrels strewn about .. Maybe New Jersey
Lotsa huge strip mines moving earth thousands of tons of earth to get those batches of minerals.
Now THOSE are UGLY .. can you agree ?
Common statistic now is 5 pounds of earth moved for every mile your magic EV travels.
I like oil pumps.. and locomotives too.

Like Jon Voight in the final minutes of Runaway Train, heading into the swirling snowy whiteout, toward his ultimate doom.

Elementary school student, 1st grade: "I like oil pumps.. and locomotives too."
Elementary teacher: "That's nice, why don't you draw some oil pumps and locomotives for the class to see?"
Seriously? Is this an adult posting?

Can anyone speak accurately about the new panels working with varying levels of sun?
I heard some of them will generate during the full moon?!

The solar constant is roughly 1.4 Kw/m^2. The Moon reflects solar light and it's not that hard to work it out, but you end up with *roughly* half a million times less light than the Sun. That's from the full moon. I doubt you can charge much with that. Then again, you are still receiving light. If you want to take it beyond this I suggest contacting the solar power people.

That’s definitely not enough to wake my charge controller up from its nightly snooze.

The Answer is Yes but not yet Aaron.
A couple good reads if you wanted.

And if you like get nuts about another thats all around us:

ETA Durian .. I came across one where the Author was saying 50w can light a red LED under Full moon .. No details on panel or location .. but would be fun to try eh ?

The charge controller has it's own overhead, even under a bright full moon the controller's parasitic draw is going to be higher than what the panel can produce. If one wanted to experiment with moonlight it would require the charge controller to be removed and directly wire a device like a tiny LED (maybe with a joule thief?). I imagine it's possible to make the LED glow especially if mirrors were used to amplify the moonlight. I know that people have used mirrors to generate more electricity on cloudy days, and also that their setups can burn out the panel if the sun unexpectedly comes out.
But if all you are looking for is to light a tiny LED, a better option would be an earth battery. I don't know how conducive our soil is to making one, but some people get enough juice to power nightlights. And it doesn't require moonbeams.

The latter part of this thread made me think of this photo. A moonless night in Chile at high elevation, the brightest feature in the sky is Venus and it's just bright enough to cast a faint shadow. As I understand it, there are very few photos of such phenomenon:

Well, I learned something new from that site; there are things such as robust and potent light. Unfortunately the site didn't go into detail about this new discovery. I also learned that the moon reflects light but also can't do so because it has no atmosphere, so in reality, it can't reflect light waves nor can it emit infrared radiation. Clearly, our moon defies all known physics.
