What is kinetic energy?

Boiler is

• coal and oil is burnt to heat water and produce steam

• many blades to capture the kinetic energy from steam

• steam is condensed back into water

Turbines have many blades

• Heat water and produce steam.

• to capture kinetic energy for steam, causing it to turn.

generator
