What will ships run on in the future?
They burn fossil fuels – diesel, heavy oil, gas oil. Traditionally, this type of drive is mechanical: The diesel engine drives a shaft that then moves the ship’s propeller. The engine or a generator also generates electricity for all the electrical systems on the ship.
Could sailing ships make a comeback?
Wind, solar electric, and hydrogen-powered ships offer innovative low- or no-carbon alternatives to fossil fuel-powered cargo vessels, with wind about to make a huge comeback in shipping, say experts. Through the late 1940s, huge steel sailing ships carried cargos on some ocean routes.

Can we have electric ships?
A Norwegian company called Yara International claims to have created the world’s first zero-emission ship that can also transport cargo autonomously. The Yara Birkeland electric cargo ship was first conceptualized in 2017 but now looks to make its first voyage with no crew members onboard later this year in Norway.
How fast could a tall ship sail?
The maximum speed under sail can be over 10 knots. Under engine the maximum is actually less: only 5 or 6 knots. But sailing is more fun than motoring, so even in light winds we often sail – albeit rather slowly!
Do cruise ships have transmissions?
Without a source of power, these mammoth cruise ships would be nothing more than hotels drifting aimlessly. So what are the options? Many older cruise ships use reciprocating diesel engines to generate power for propulsion. The power of the engine is fed through a transmission to propeller shafts.
Do cargo ships have transmissions?
Most modern larger merchant ships use either slow speed, two stroke, crosshead engines, or medium speed, four stroke, trunk engines. Ships propelled by medium or high speed diesel engines may have one or two (sometimes more) propellers, commonly with one or more engines driving each propeller shaft through a gearbox.
