How to encrypt power transmission line?

- avian 8y agoCan you encrypt gasoline, so that only authorized people can burn it? This question does not make sense. Electrical power is not information. It can’t be encrypted. You can have power switches that only switch on when a valid key is presented, but with physical access you can always bypass a switch.
