"The 'driverless car' is the new 'horseless carriage'." -- Bruce Sterling
It isn't the green laser light that Niven and Pournelle employed in The Mote in God's Eye, but the radiation signature should be distinctive anyway.
"An alternative approach is to use a light sail propelled by microwave radiation beamed from Earth. In this way, the spacecraft which would not need any fuel for propulsion. This has the potential to accelerate a one-ton spacecraft to around 60 kilometers per second during a trip to Mars, that’s triple the speed of the fastest chemical rockets.
Although expensive to build, such a system would be extremely cheap to operate. Guillochon and Loeb estimate that such a system might cost $30 billion to construct but only $40 million per mission to propel.
If the same economics hold in other planetary systems, Guillochon and Loeb argue that other civilizations may be currently exploring their planetary systems using light sail technologies. If so, this provides a new way to spot the tell-tale signs of the technology at work."
Though some of the video looks rather spectacular, it was all confined to a single warehouse.
(If the recent Tinjin explosion were a whale, this would be a tadpole.)
