First crewless, zero emissions cargo ship will set sail in Norway

Wow, so cool! Basically a giant 80 meter long RC ship with an autopilot! :-)<p>It also has a way smaller battery capacity than I would have expected to be necessary for a (small) cargo ship, even for the short range of 64 nautical miles (~120km). Ships are pretty efficient, apparently. :-D

Assuming it&#x27;s more than a publicity stunt, this is the kind of thing we really need to combat climate change. Cargo ships are enormous polluters (and not even just of greenhouse gases)

Hasn&#x27;t Tesla done this already?
