I have always wondered how high we can push the voltage on transmission lines. Maybe carbon nanotubes being as conductive as copper but lighter and stronger than aluminum could allow significant transmission of electricity across time zones, stretching out the load and allowing solar to power dark areas for some time without increasing storage. Transmission towers would need to get obscenely large, but the lighter lines would a allow for fewer of them.
