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.

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

When air rises, moist air cools at a lower rate than dry air.

An air purifier is a device which removes contaminants from the air.

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

Air detection

Air action

Air Cooler

This one we actually first discovered back in the air days the bad old air days, as we used to say when we were doing these kind of dives with air.

Moist air has more water vapor than dry air, so more latent heat is released into the parcel of moist air as it rises.

Houses in the Air

Air pollution

There's a convergence. So, wherever the rain is falling, the air is drawn towards it to replace the air that's rising.

Dry air does not have as much water vapor, therefore dry air cools at a higher rate with vertical movement than moist air.

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.

It's acoustic vibrations in the air, little waves of energy in the air that tickle our eardrum.

This makes moist air generally less stable than dry air (see convective available potential energy).

The unit heats air at the bottom, reducing its relative humidity, and the natural tendency of hot air to rise brings this low humidity air into contact with the clothes.

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.

He fights windmills.

The air conditioner was on.

The ratio of this air to the amount of air flowing through the engine core is the bypass ratio.

A dual hose unit draws air to cool its condenser from outside instead of from inside the room, and thus is more effective than most single hose units.

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

Transport support base for the air staff.

Air pollution atmosphere

This in turn drew cooler air in from the lower vent, providing constant circulation of cooler air.

That is, for the same vertical movement, a parcel of moist air will be warmer than a parcel of dry air.

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 weather front forms when the moist air over the Pacific meets the cooler continental air mass.

Many kinds of animals have vanished from the earth.

All hope of winning the game vanished.

Tear gas spreads through the air.

I was very scared.

That's because the bubble vanished into thin air.
