It is carbon neutral not Zero Petro. for example Bill gates is carbon neutral Yet he uses his Jet a lot and many flights are long haul to Ashia EU and Africa.

Of course he owns the company that makes the equipment and probably writes off the equipment as R&D and will make a bundle if this is ever widely adopted.

The only thing stopping major carriers from going nuclear is they are designed to be sold by major carriers in 15~ 20 years. then Maintenace expenses make them to expensive to maintain and they are sold to second tier companies that basically run them till they fail with minimal Maintenace. if we are lucky they are scrapped.

The companies that operate these do not like the publicity of a ship going down. So some are not reported for years some never are reported. Only if a distress call goes out are they reported promptly. Captains are penalized for good and bad distress calls by these second tier companies, so many captains hold off till it is to late. Many turn off ALS when at Sea. These are called ghost ships. I cruised my boat from Florida Keys to New York about 50 ~ 200 miles offshore. At least once a night I would see a boat on Radar with absolutely no locations signal. All you can hope is they see your ALS and stay clear but this is the responsibility of the smaller vessel. It is unlikely they could detect me on radar because I was small. Unusually they can only see me under 3 miles. A radar reflector high on my mast might extend this to 5 miles. Yes I always used one.
