 Well, 100 zettabytes is 10 to the power of 23 bytes. So that's a 10 with 23 zeros after it. So a lot of bytes. And one byte is basically saved as on and off capacitors. And a capacitor is? It's just a bit of electrical kit that stores charge. But the number of electrons needed to charge a capacitor really varies. So I'm going to make a very guessy guess.
