An extremely advanced civilization might want to send power from star to star across their galactic empire. How could they do this? A new paper suggests that it could be done with multiple gravitational lenses, focusing the energy from one star into a tight beam and then another receiving lens to receive the power. It would take much more advanced technology than anything we can do, but it might be another way to search for civilizations in the Universe.
