- Cthulhu_ 4y agoI think a lot of commenters in articles like this will only think about automotive as a use case for alternative engine designs. I'm reminded of a linear piston engine (iirc two pistons that just go back and forth without their motion being translated into rotation; one where they were side-by-side moving alternately, the other one where they'd actually move towards each other and share a combustion chamber). The use case for that was to have the pistons move through coils, thus generating electricity. We used to have a flashlight that works with the same principle, shake it to generate electricity.
- themaninthedark 4y agoMy first thought went to cargo ships. They require huge motors, so I imagine that if you can keep or gain performance while reducing size they would be very interested.
- adgjlsfhk1 4y agothis is backwards. the reason cargo ship engines are big is because they don't care about size. they would rather have a 2x bigger engine that was 1% more efficient
- leansensei 4y ago> this is backwards. the reason cargo ship engines are big is because they don't care about size. they would rather have a 2x bigger engine that was 1% more efficient Depends on the fuel cost.
- lazide 4y agoHow so? 2x bigger has no bearing on fuel cost, but efficiency does.
- LargoLasskhyfv 4y agoOr the fuel volume. Think of LNG-powered LNG-tankers. Like these: https://en.wikipedia.org/wiki/CMA_CGM_Jacques_Saad%C3%A9 https://en.wikipedia.org/wiki/CMA_CGM_Jacques_Saad%C3%A9
- anecdotal1 4y agoDoes it? They only need to get to it international waters and then they switch to bunker fuel which is as cheap as it gets
- lb1lf 4y agoThere's an awful lot of room on a cargo ship. They don't care too much about size. They only care about total cost of ownership. Edit: ninja'd!
