Thank you for that explanation, just a thought has there been any experiments with using the energy of the waves to help save energy? I remember a TED talk, a decade ago a about a flexible sailing boat...cant seem to find the link and then there is this https://en.m.wikipedia.org/wiki/Blackbird_(land_yacht)#:~:te https://en.m.wikipedia.org/wiki/Blackbird_(land_yacht)#:~:te... Also I know there were some experiments with electrostatic or bubbles on the hulls of these huge ships... https://www.google.com/amp/s/www.marineinsight.com/green-shipping/how-air-lubrication-system-for-ships-work/ https://www.google.com/amp/s/www.marineinsight.com/green-shi... Also what about huge autonomous kites...? https://en.m.wikipedia.org/wiki/SkySails https://en.m.wikipedia.org/wiki/SkySails I mean surely such systems are complicated but with today's sensors and autonomous systems i'm sure people could come up with something that is better than burning 3rd grade fuel to bring us gadgets and junkets...
