One limitation of wind power is that?
One limitation of wind power is there is no power supplied when the wind is not blowing. It cannot be used as a great dependable source of energy.
What is the size of a wind driven wave?
The size of a wind-driven wave could be anywhere from 1ft. to about 10-15 ft.
Why is a windmill not a perpetual motion machine?
Perpetual motion machines do not exist. There is no machine that will keep on moving by itself without any added power. Windmills are driven by the wind. When the wind stops blowing, the windmill stops turning.
Is wind power effective?
The effectiveness of wind power depends on where the wind power is coming from. Certain locations with a lot of wind are deemed effective at supplying wind power.
What are the ways in which power stations can be powered?
Power turbines are driven by steam. Steam can be raised by thermal, nuclear or geothermal processes. Wind and water can also drive a generator. The auxiliaries for a power station (which I think is what this question is asking) are typically powered by step down transformers within the power station. In nuclear power stations there are often standby-critical supplies which are driven by gas turbines or diesel generators.
What is power-driven vessels?
A power driven vessel is often understood to be a mechanically driven boat. Human power as in rowing or wind driven power is not usually considered power driven.
What is wind power replacing?
one of the things wind power is replacing water driven hydroturbines that generate electricity. Ultimately, if the proper power converters are produced, wind power can eliminate our need for petroleum based power plants.

What should you do when operating a power driven vessel and your vessel is being overtaken by a sailing vessel?
Steer into the wind.
What effect does the wind have on the way you launch the rocket?
The wind negatively affects the rocket. This is because the air resistance, as the rocket goes up, increases rapidly and slows down the rocket.
How will the wind affect the rocket after it is launched?
Wind will affect the rocket causing it to go off course or crash into a tree.
How do power companies prduce electricity?
Via big generators. Generators are rotating machines that output electric power when the shaft is spun by an external source, sort of like electric motors in reverse. The generators are driven by many things: water turbines, which are driven by water from a dam Steam turbines, which are driven by steam from boilers heated by burning oil or coal, or nuclear power, or geothermal power. Wind turbines, driven by wind Solar cells And probably a few other things... Actually there is one source of electric power not driven by a generator, and that is fuel cells that produce electricity directly by chemical reaction.
When can a power driven vessel becomes a sailing vessel?
When being propelled by wind alone and without auxiliary motive force.
What is the size of a wind driven wave?
The size of a wind-driven wave could be anywhere from 1ft. to about 10-15 ft.
What wind driven material causes erosion?
Sand, blown by the wind.
What are wind driven currents?
Surface Currents
