What is the function of a turbine?

• When it spins, it makes sparks, inducting electricity.

• It transfers the energy from the flow of steam or water to the generator.

• It speeds up the steam or water to keep it at a steady pace.

• It controls the steam or water so it can be pumped around in a cycle.
