Article quotes `40 megawatt-hours of installed capacity.` - Surely this can get you pretty far from Tasmania to South America.
- chii 9mo agoapparently, 40MWh of capacity is enough to travel 40 nautical miles. The distance between Tasmania and South America is around 6,500–7,500 nautical miles.
- amelius 9mo agoFor comparison, a wide body airliner needs ~0.15MWh to travel 1 nautical mile.
- eesmith 9mo agoA wide body airliner doesn't carry "up to 2,100 passengers and 225 vehicles".
- verandaguy 9mo agoIt also does so in a medium where the main drag force is induced by air rather than water, which is probably a comparably significant factor
- potato3732842 9mo agoIt also needs to beat up that air enough to make the resultant forces overcome gravity acting on the airliner whereas the ship just gets to float there. Apples to orages.
- eesmith 9mo agoYup. Or to structure it a the earlier comment: for comparison, it takes me about 0.000065 MWh to cycle 1 nautical mile. That's a couple of apples.
- nandomrumber 9mo agoYou also aren’t doing so while carrying 2100 passengers sms 225 cars, I imagine.
- nineteen999 9mo agoPlus they are going to get very waterlogged cycling that nautical mile.
- nandomrumber 9mo agoSome dedicated cyclists will cycle in any weather.

- amelius 9mo agoAnd a maglev train? https://en.wikipedia.org/wiki/Maglev https://en.wikipedia.org/wiki/Maglev
- rcxdude 9mo agoI would be extremely surprised if the ship were designed to use 100% of its capacity in one way of its intended route.
- jacquesm 9mo agoThe drag on a vessel is orders of magnitude larger than the drag on a car.
