Paddle wheel

It has several uses, of which some are: The paddle wheel is an ancient invention but is still used today in a wide range of industrial and agriculture applications.

Paddle wheels would enable ships to travel without needing wind or oars.

They were made obsolete by propellers, which had greater propulsion with lower weight and fuel usage.

This was demonstrated by an 1845 tug-of-war competition between HMS Rattler and HMS Alecto with the screw-driven Rattler pulling the paddle steamer Alecto backward at 2.5 knots (4.6 km/h).

In the rotary-to-linear direction, it is driven by a prime mover such as an electric motor or steam engine and used to pump a fluid or propel a vehicle such as a paddle-wheel steamer or a steamship.
