Turbine
* Most turbines change directions as the wind changes.
* Most turbines convert energy
  - kinetic energy
  - power
  - wind energy
* Most turbines drive electrical generators
  - wind generators
* Most turbines generate current
  - electric current
  - electricity
* Most turbines have brakes
  - either two or three blades
  - heads
  - power output
* Most turbines make electricity
  - enough electricity
* Most turbines produce electricity
  - provide electricity
* Most turbines turn generators
  - metal shafts
  - use wind
* Some turbines are turned by wind, some by water, some by steam
  - change energy
  - have magnets
  - involve energy conversions
* Some turbines spin electric generators
* are driven by a fluid which acts as an intermediate energy carrier
  - engines
  - integral to the operation of hydroelectric dams, but they also can injure fish
  - mechanical devices
  - most effective in shallow water
  - the most efficient way of converting heat into mechanical work
* catch the wind's energy with their propeller-like blades.
* contain metal coils surrounded by magnets.
* have blades
  - fans
  - limitations
  - the ability to also extract energy from the stream of gases in a jet engine

  - vanes
* mechanical rotary component which produces work by action of the working fluid.
* require assemblies.
* rotary engine
* to generate electricity.
+ Electricity generation, Methods of generating electricity, Turbines
  * Rotating turbines attached to electrical generators produce most commercially available electricity. Turbines are driven by a fluid which acts as an intermediate energy carrier.

Turbine engine
* All turbine engines have an inlet to bring free stream air into the engine.
* come in a variety of forms.

Gas turbine
* are delicate and expensive machines
  - one type of internal combustion engine
  - therefore open cycles, and piston engines are closed cycles
* have exhausts wherein the heat goes unutilized.
* incur relatively low capital and operating costs.
* offer the advantage of reducing reliance on long-distance transmission.
* produce a lot of moisture.
* work around the clock.

Impulse turbine
* Some impulse turbines use multiple jets per runner to balance shaft thrust.
* change the velocity of a water jet.
+ Water turbine, Theory of operation, Impulse turbines: Tools :: Electricity :: Hydropower
  * Impulse turbines change the velocity of a water jet. The jet pushes the turbine's curved blades which reverse the flow.

Large turbine
* Most large turbines generate power
  - have power output
  - turn shafts
* have output

Steam turbine
* Most steam turbines drive generators.
* are one of the most critical and expensive equipment in a power station
* can supply more power than large diesels at less cost.
* come in many configurations.
* produce a rotary motion.

Water turbine
* Some water turbines are designed for Pumped storage hydroelectricity.
* can undergo large pressure transient which can lead to massive failure.
* have very similar operating characteristics and problems as ducted propellers.
* rotate at higher speeds, are lighter and more compact.
* transform water power to driving energy with nearly no frictional loss.
+ Water turbine, Theory of operation, Pumped storage: Tools :: Electricity :: Hydropower
  * Some water turbines are designed for Pumped storage hydroelectricity. They can reverse flow and operate as a pump to fill a high reservoir during off-peak electrical hours, and then revert to a turbine for power generation during peak electrical demand. This type of turbine is usually a Deriaz or Francis in design.
