from The American Heritage® Dictionary of the English Language, 4th Edition
- n. Any of various machines in which the kinetic energy of a moving fluid is converted to mechanical power by the impulse or reaction of the fluid with a series of buckets, paddles, or blades arrayed about the circumference of a wheel or cylinder.

- n. any of various rotary machines that use the kinetic energy of a continuous stream of fluid (a liquid or a gas) to turn a shaft

- n. A water wheel, commonly horizontal, variously constructed, but usually having a series of curved floats or buckets, against which the water acts by its impulse or reaction in flowing either outward from a central chamber, inward from an external casing, or from above downward, etc.; -- also called turbine wheel.
- n. A type of rotary engine with a set of rotating vanes, diagonally inclined and often curved, attached to a central spindle, and obtaining its motive force from the passage of a fluid, as water, steam, combusted gases, or air, over the vanes. Water turbines are frequently used for generating power at hydroelectric power stations, and steam turbines are used for generating power from coal- or oil-fired electric power stations. Turbines are also found in jet engines, and in some automobile engines.
from The Century Dictionary and Cyclopedia
- n. A pair of turbines fastened on one shaft, either back to back or face to face, an arrangement which balances the pressure due to the weight of the driving water-column, and releases the stresses on the footsteps or thrust-bearings: usual in modern high-powered installations.
- n. A water-wheel driven by the impact or reaction of a flowing stream of water, or by impact and reaction combined.

- n. rotary engine in which the kinetic energy of a moving fluid is converted into mechanical energy by causing a bladed rotor to rotate
What I said was that if the specification for "turbine" is false, then we have nothing to hang the design inference on, it may be designed, but there is no empirical reason for saying so since there is no specification.
Gibbs quipped that when it came to other renewable projects, "I doubt a small wind turbine is in the offing."
The bladeless wind turbine is completely enclosed in a relatively small compact unit.
Fundamentalist writes: dearieme: a toy steam turbine is not the same thing.
Oh come now, a toy steam turbine is not the same thing.
Based upon meteorological data for the Al Quoz site, the 5 MW horizontal axis wind turbine is capable of operating for 1,600 hours per year, while the two solar systems could operate for 2,400 hours per year, adding up to a yearly output of approximately 20,000 MWh.
A steam powered turbine is most efficient when run at close to full power.
The towers require dehumidifiers that run even when the turbine is not generating.
Bloomberg News A rotor for a Suzlon Energy wind turbine is raised in Ohio, Ill. The American Wind Energy Association disputed the findings, saying only three of the 33,000 wind turbines in the U.S. were made in China and that the vast majority of foreign suppliers produce turbines for the U.S. market in facilities here.
The potential for wind power in a given area grows when a taller turbine is selected.
