Speaking of which. Has any supposed deposit on either Moon or Mars been actually confirmed as accessible and suitable for actual resource extraction, with some method better than remote sensing?

Is this the dumbest thing to ever come from /pol/?

Care to elaborate? Sounds interesting.

I kind of understand it better now. I think so. Let me see if I got it right. In the example at >>8939269, the "voltage drop" would be 0.5 and 0.5 if resistors were the same size. So in the left example at >>8939309, the first voltage drop (5 ohms) would be 4 times the size of the second voltage drop (20 ohms) (5:20 = 1:4), in such a way the sum would be equal to 100? So we would have 20 and 80?

And if the two last lines you wrote are true, then why do batteries work the way they do? I mean, let's say... I'm an astronaut, and I'm floating in space. If I hold a phone in space, the phone would still work if the battery is charged, right? It's not connected to any ground, it's in fucking space. So what exactly is this ground? I understand an earth wire or whatever the technical name gives a kind of infinite sink for electrons because it's so massive compared to the circuit. So how come things with batteries supposedly work without being attached to earth or comparable body?
