Interesting. Sounds right. I remember an engineering prof explaining grounding as the earth being basically an infinite capacitor. And on YouTube there's a channel called Electric Universe (I think) that says electricity moves through space, which is exactly the opposite of what's taught, and I don't see how it could be possible, but the effects certainly appear to demonstrate it. Electricity, as we understand it, needs a medium to move across. 

But this is great - if we're seeing causes and effects but can explain the connection, that means we're about to get better at physics, which means I'll soon take possession of my moon, Ganymede.
