a Reflects adjusted distribution of approved resources between military and police personnel and operational costs categories of expenditure.

Turbines equipped with advanced cooling.

In hot gas (gas turbine), turbines are driven directly by gases produced by the combustion of natural gas or oil.

Four little engines, 22 kilos thrust each, turbines working with kerosene.

On 31 July 1945 the Lynn plant became the Aircraft Gas Turbine Division .

It is the first skyscraper in the world to integrate wind turbines into its design.

It is a rotating mass of gas, dust, stars and other objects, held together by mutual gravitational attraction.

Small wind turbines may be as small as a fifty watt generator for boat or caravan use.

The Brush wind turbine had a rotor 17 m (56 foot) in diameter and was mounted on an 18 m (60 foot) tower.

In addition to aircraft engines, Pratt Whitney manufactures gas turbines for industrial and power generation, and marine turbines.

Though less efficient, its simpler structure is less expensive than other low head turbines of the same capacity.

Originally designed as turbotrains to be powered by gas turbines, the prototypes evolved into electric trains with the 1973 oil crisis.

Steam turbines can also be used directly to drive large centrifugal pumps, such as feedwater pumps at a thermal power plant.

In the past five years the industrialised skyline has been changed by the addition of large numbers of wind turbines taking advantage of the exposed coastal conditions.

We see scary pictures of dry riverbeds (the result of global warming), along with plenty of pretty solutions like wind turbines and solar panels.

They generate power by burning natural gas in a gas turbine and use residual heat to generate additional electricity from steam.

The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) defines small wind turbines as those smaller than or equal to 100 kilowatts.

The response was predictable because Slaughter s article is one that is published in the US by a revolving cast of powerful (most often white) women every three years or so.

The wind turbines are expected to provide 11 to 15 of the towers' total power consumption, or approximately 1.1 to 1.3 GWh a year.

Today, it is often remarked that Denmark is providing every third terrestrial wind turbine in the world, creating billions in income and jobs.

Not surprisingly, the leading Danish wind producer is today urging strong action on climate change that would imply even more sales of wind turbines.

However, others have noted that although the specific part may be only found in the 900, in both cases the intermediate pressure turbine and lubrication system are suspect.

In 1897, Robert W. Paul had the first real rotating camera head made to put on a tripod, so that he could follow the passing processions of Queen Victoria's Diamond Jubilee in one uninterrupted shot.

These policies include a cap and trade initiative known as the Emissions Trading Scheme, steep fuel taxes, and ambitious programs to build windmills and other renewable energy projects.

During 2009, seven large wind turbines, likely Vestas 3MWs totalling 21MW capacity, were erected in the sea north of Sprogø to contribute to the electrical demand of the Great Belt Link.

A few years ago, however, the Danish Economic Council conducted a full evaluation of the wind turbine industry, taking into account not only its beneficial effects on jobs and production, but also the subsidies that it receives.

The Kite Wind Generator (KWG) or Kitegen is claimed to eliminate all the static and dynamic problems that prevent the increase of the power (in terms of dimensions) obtainable from the traditional horizontal axis wind turbine generators.

It was the team at Ampex, led by Charles Ginsburg, that made the breakthrough of using a spinning recording head and normal tape speeds to achieve a very high head to tape speed that could record and reproduce the high bandwidth signals of video.

For example, cutting a ton of CO2 with on shore wind turbines in Germany probably costs about 35, avoiding about 14 cents of climate damage per dollar. But offshore wind turbines cost about 150 per ton of CO2, avoiding just three cents of climate damage per dollar.

A good illustration is Denmark, which early on provided huge subsidies for wind power, building thousands of inefficient turbines around the country from the 1980 s onwards.

This conclusion has been reached by research conducted by Charles Meneveau of the Johns Hopkins University, and Johan Meyers of Leuven University in Belgium, based on computer simulations that take into account the detailed interactions among wind turbines (wakes) as well as with the entire turbulent atmospheric boundary layer.
