Re: 240 volts?
You're amusingly/worryingly wrong.
At higher frequencies, current tends to concentrate at the surface of a conductor*. This leads to an effective higher conductor resistance and consequent lower current and power handling capabilities.
* This is why multi-strand conductors are better than solid ones for high frequency currents, because there's relatively more surface area. But if you want to transfer power, low frequency is better.
