The Emma Mærsk is powered by a Wärtsilä-Sulzer 14RTFLEX96-C engine, the world's largest single diesel unit, weighing 2,300 tonnes and capable of 81 MW (109,000 hp) when burning 14,000 litres (3,600 US gal) of heavy fuel oil per hour.
So bitcoin is equivalent to 425 Emma Mærsks going full bore continually.
That'd be 6.3 million TEU - which interesting means that for those big ships, a liter of fuel moves one TEU for one hour.
So even if it had 150,000 humans on board, the humans might consume less liquids than the engine...
Those humans would also only use 1/6th as much energy (when assuming around 9.2m Calorie per liter of diesel). So the energy used by that engine could also "run" a million humans. Whatever that ship is carrying, it might be more energy efficient to let people carry it...
Burning through four liters of diesel a second/a bathtub a minute is insane.
I'm a bit tired, but I hope I got that math about right.
