Interesting EngineeringWorld's first 10,800 car carrier with solar power delivered by ChinaChina has delivered the world's first 10,800-vehicle car carrier equipped with a solar power system, combining photovoltaic technology with LNG dual-fuel propulsion.

The ship’s solar system can produce up to 200 kilowatts at its peak and generates about 1,000 kilowatt-hours of electricity daily

The carrier also uses a dual-fuel propulsion system that operates on conventional fuel oil and LNG.

I was real excited for electric shipping since one ship like this produces an unbelievable amount of pollution, but this is kinda pitiful in comparison to the power needs of these ships:

The propulsion arrangement on each ship includes one MAN 6S60MC-MK 10.5-GI-EcoEGR main engine with a rated output of 14,950 kW (20,000 hp) driving a propeller, a 2,000kW bow thruster, and three Himsen 8H22CDF 1,500kW generators. The LNG fuel is stored in two type C tanks with a combined capacity of 1,700 cubic metres (370,000 gallons).

1000kwh isn’t nothing and I suppose it might meet the ship’s power needs while in port (edit: nvm average shore power consumption for a panamax is 600kw) but this feels like a whole lot of greenwashing given they don’t mention the power requirements in the article.

We already do with tidal generators.

And theres ways to follow currents for extra help, but you’re limited to that and where the current moves.

Anything else and you’d have to violate the laws of physics.

It’s like putting a wind turbine on an electric car. The increased drag would cost more electricity than the turbine could produce.
