What is meant by combined cycle?

• A really fast motorbike

• Natural gas is used for a combustion turbine, and the hot

  exhaust superheats water to produce steam, which turns a

  steam turbine

• Wind turbine wind vane.

• Fission is used for a wind turbine, and the hot

  exhaust superheats water to produce fossil fuel, which turns a

  wind turbine
