        i.e. 1 C is a crazy high amount of charge 😉

        When I was little, I think capacitors were generally measured in microFarads. Now you can get capacitors measured in Farads. (And they aren't the size of a cathedral.)

        Just to be pedantic: the weight of a 1 million ton(ne) (10^9) mass is ~10^10 N

        The repulsive force between two objects charged with 1 C each standing 1 m apart should be approximately 9 x 10⁹ N. From Coulomb's law, F = kₑq₁q₂/r² = (9 x 10⁹ N⋅m²⋅C⁻² ⋅ 1 C ⋅ 1 C) / 1 m² = 9 x 10⁹ N.

        I think they meant force equivalent of 1 milion ton (9.8*10^9) which is pretty close
