could you make a windmill powered ship? would it be inferior to a sail powered ship?

>what is efficiency
Every mechanical process loses some of the energy to inefficiencies. You can't make a windmill+gearbox+prop that is more efficient than just using a sail that takes up the same area.

>>7808268
what about when you're sailing in a different direction than the wind is blowing?

>>7808273
goof question bro :)

You can sail in any direction relative to the wind. Even against the wind.

doesn't that require tacking though?

I remember reading about car that used a wind turbine (or was it a sail?) on top of it and it could go faster than the wind.

Lift vs drag baby!
