What a 107 thousand horse power engine looks like

Pretty sure its for rocket launching mechanisms? Although I may be mistaking that for something else

It's either a generator for a small factory or a motor for a large boat

"Small"

Did I say the engine can fly you walnut I meant do they put it in a plane?

"You walnut"

Plane engines are small (relatively), light and efficient. An engine this size would be FAR to large and heavy to power a plane. It could have enough power but it would only be able to efficiently power a HUGE prop plane which wouldn't have enough force to get its self off the ground due to the simple size of the propeller (could be used for a massive helicopter but good luck with carrying the fuel). This engine is likely the engine for the ship, like a battleship, cargo or a cruise ship (as said by guest below). They can carry the weight and need the power and have space for the fuel so it is logical.
I'm NOT an engineer, so don't take my word as gospel.

It's for a cargo ship
