What are the disadvanteges of wind turbines?
The wind blows at a variety of speeds. The turbines need to produce electricity at a standard voltage. If the blades speed up and slow down as the wind changes speed the voltage will vary. They are hard to get right that way. They are placed in windy areas which is where birds fly. If they go too fast, they will kill a number of birds and thus be bad for the environment. The noise from the turbines can be unpleasant.
How do wind turbines create eletricity?
Yes, but only if they go round in the wind and they are connected.
Why do wind turbines spin?
Wind turbines spin because of the force of the wind turning the blades. The wind pushes the blades, causing them to rotate. This rotation is then converted into electricity through a generator within the turbine.
How much technology does it take to find wind turbines?
All it takes is the will to go out and look for them.
Why does wind turbines have long blades when short blades go faster?
Long Blades Catch More Wind Then Short Blades
What happens to a wind turbine if there is a hurricane?
When the wind picks up the turbines move faster and produce electricity. faster winds mean more electricity in less time. There is also a safety mechanism because in very high winds the turbine can go too fast and damage/destroy itself. To prevent this, the blades have variable pitch, and thus the speed can be limited. In very strong winds the blades will nearly feather themselves...ie:Turn edge on into wind. This function is also used when the generator is under repair in order to stop the machinery from turning.
Is it possible to attach small wind turbines over trains?
If you're talking about sticking turbines onto the train: It's possible, but pointless. The turbines would spin due to wind speed generated by the movement of the train, so all the power that is going into the turbines has come from the train in the beginning. Basically you're using the motor of the train to spin the generator of the turbines. The train has to work harder, and the energy you get from the turbines will be less than the extra energy that's being spent by the train. If you're talking about sticking wind turbines by the track, to spin by the pressure wave: That's also possible, but almost as pointless. Turbines by the track would resist air flow, and when the train is travelling it will push a cushion of air in front of it. Something getting into the way of this air cushion, (like turbines) would basically make the air in front of the train denser, and harder to push through. On top of that, there aren't many places where trains go by all the time, so the turbines wouldn't have much to work with.
How can a sail boat go twice the speed of wind?
it cant
How fast does wind go when there is a tsunami?
A tsunami is not a wind-related event, so the wind could be going any speed.
Why are wind turbines in the world?
Wind Turbines are an efficient way of creating electricity with zero air pollution. Currently, England powers 13 percent of their country by wind turbines. Wind turbines and Solar panels are important in two ways. They are free and they cause no pollution. Of course there's the cost of your panels and turbines although the amount of electricity it will produce over its lifetime will greatly outweigh its cost in currency. The U.S. still imports the majority of its oil to fuel our nation, which is costly and messy. The prevailing winds that travel across the great plains, in addition with several hundred or thousand offshore wind farms, along with solar fields in the southwest. We could ultimately fuel our entire country off the wind and sun. This obviously would be costly and an extremely long term project, although over time, whether we like it or not, oil will run dry. GO WIND TURBINES!!
Why shouldn't you use wind turbines?
I think that wind turbines are a bad idea. Think about how much it made to make that wind turbine. How much energy it took to make it. Did you know that they will fling ice chunks off flying? Some times whole propeller will go flying off, then they'll hit a building. They have been recorded to fly up to almost a mile. Plus the very annoying noise they make.
Flying with the wind a plane went 366 mph flying into the same wind the plane only went 310 mph what is the speed of the wind How fast would the plane go if there were no wind?
The speed of the wind is 28 mph. To find the speed of the plane with no wind, we would simply subtract the wind speed (28 mph) from the speed of the plane flying with the wind (366 mph) or add the wind speed to the speed of the plane flying into the wind (310 mph), resulting in 338 mph for the speed of the plane with no wind.
