Turbine

A turbine is used in chemical power plants and nuclear power plants to generate energy. To allow them to generate energy, you need to have a fuel (such as natural gas for the chemical power plant or refined uranium for a nuclear power plant) which heats up the plant. You also need water (placed in the reactor using a capsule) to allow the turbines to spin and thus start generating energy.

Note that for nuclear power plants, turbines are not compulsory, since nuclear fuel (refined uranium and plutonium) generates energy regardless of temperature, at a steady rate; but the turbine may still be used to boost production while the reactor is hot.
