text: The energy that can be extracted from the steam is conveniently expressed in terms of the enthalpy change across the turbine.
text: When the turbine turns energy is extracted from what ever is making the turbine turn, for example wind or water or steam.
text: The steam is then directed to the moving passages or buckets where the kinetic energy is extracted.
text: Not all the kinetic energy of the wind can be extracted, because there must be a finite velocity as the air leaves the blading.
text: One these eddies are loss to the useful energy that can be extracted from the system and second, as they are in opposite direction, they decrease the energy of the incoming steam stream.
text: The process is repeated until all the energy is extracted from the steam.
text: If pressure is constant then only kinetic energy is extracted.
text: This reduces pressure around the turbine and allows more air to pass through the turbine, but not enough to account for the lack of energy being extracted.
text: It's a disk in space where fluid energy is simply extracted from the air.
text: If a diffuser is used to collect additional wind flow and direct it through the turbine, more energy can be extracted, but the limit still applies to the cross-section of the entire structure.
text: Elsewhere in the UK, annual energy of 50 TWh can be extracted if 25 GW capacity is installed with pivotable blades.
