Re: Beyond Electricity?
I agree with Metryq - electricity and the electromagnetic force are fundamentals and will never be obsolete. Electricity in itself is not what it's about, it's all about the transfer of energy in a method that we can use.
The irony being that steam is not obsolete - we still use this method for generating electricity (including Nuclear Power). All we do is convert the energy from steam to electricity and pass it down the wires.
It is quite possible that our methods of distribution may change however. Perhaps a tight beam of energy instead of all those pylons and cables.
