Ireland has many rivers and can get power from them. Ardnacrusha is the most well known of the power stations generating Hydroelectric power. It is in Co. Clare, and harnesses the power of the river Shannon. Turlough Hill in Co. Wicklow is another well known one.
Is a voltage source a zero or infinite impedance?
Obviously it's not infinite impedance--that would mean it soaks up all the voltage. It can't be zero impedance either...that would be a superconductor, and there aren't many of those around. Voltage sources have impedance, but it's not infinite. Sometimes the impedance of the source is critical--radio frequency amplifiers have to be impedance matched to their transmitting antennas if you don't want to burn them out.
Why the hydro electric power station have high transmission distribution cost?
to help pay for line maintenance, employees, and cost of fuel.
Can you cross from Oregon to wash on Bonneville dam?
NO! Only authorized personnel can cross the dam. The general public must use the "Bridge of the Gods" east of Bonneville, off I 84. (You'll need a dollar.)
How do you make a model hydroelectric plant?
You will need a water reservoir, some form of turbine, and something connected to the turbine to represent a generator.
The water reservoir can be just about anything that can contain water at an elevation above that of your turbine. In the real world, this is usually a dam, so you may want to model something that looks like a dam.
Water from the elevated source is allowed to flow from the source past a water turbine. You could make a waterfall and paddlewheel so that people can see the workings, but in an actual generation station, this is a pipe and the turbine is enclosed.
The turbine turns as a result of the water flow. A generator is connected to the shaft of the turbine. You can use a permanent magnet motor for your generator. Just hook up a voltmeter to what would normally be the battery leads of the motor to show the voltage being generated. Chances are, your model won't be able to generate enough power to light a bulb, so showing the voltage with a voltmeter is a simple way of demonstrating the principle.
A:We need these things to make a hydroelectric power station:1.cardboard
2.aluminium foil or butter paper
3.chart paper
4.a generator
5.a turbine made of plastic
6.a 1.5 volt battery
Where have wave's energy been used successfully for electricity?
The world's first commercial wave farm is based in Portugal, at the Aguçadora Wave Park, with a capacity of 2.25MW.
It will soon be expanded to give it a capacity of 21MW.
There are other pilot schemes of various designs all over the world.
Arguable... the first form of hydropower may be considered to be the waterwheel. In which case the inventor is unknown.
Very good. Water is fed to the top and the weight of the water causes the wheel to move downward
How do you make a mini generator?
There are an unlimited number of ways you could make a mini generator. You could use fan power for example.
If you were to build a 5 mega liter dam how much land would be needed based on an average depth dam?
Well, let's suppose the reservoir would average 50 meters deep. Lake Mead is a lot deeper at Hoover dam, but it's also a pretty unusual reservoir. There are 1000 liters per cubic meter, so 5*10^6 liters = 5000 cubic meters. With an average depth of 50 meters, that's a surface of 100 square meters. Considerably smaller than you're average suburban lot. That means we're talking about a farm pond, not a national monument. So maybe 50 meters is a lousy estimate of the depth. Let's say it's 2 meters. So now we have a surface area of 2500 square meters, which is 50 meters on a side, which would be a pretty good sized farm pond. But you get the idea by now. It's somewhere in that range.
How did the Snowy Mountains Scheme affect Australia's population?
When the Snowy Mountains Hydroelectric Scheme was begun, it required more manpower than Australia could offer, especially people with particular skills and training. The Scheme attracted tens of thousands of skilled immigrants, resulting in not only an increase in Australia's population, but in its cultural diversity. These migrants were happy to come to Australia as their own countries were suffering post-war economic depression, and Australia offered new opportunities for them.
What was the World War 1 trench lighter used for?
Matches were used by soldiers to find their way in the dark. But the intense initial flare of matches gave away their position too easily, and many lives were lost because of this. Hence, the need for combustion without a great initial flare was born. Inventors started improving the design of lighters and by 1918 when the war ended, they were able to be produced somewhat easier.
The real answer is the supply of matches during the war was restricted because timber was required for other purposes and the supply of chemicals difficult to maintain. Matches were also susceptible to dampness so lighters were poplar - In fact, lighters were common from the beginning of the war, ranging from tinder lighters to trench art lighters made from bullets or other discarded material. Wartime lighters were often manufactured behind the lines in ordnance and engineering workshops. J.Williams
For static purposes, this is not a difficult task, for the equations relating the model to the full sized dam are linear.
However, when dynamic behaviour is considered, then the relationship between model and full-size is not linear. Effects such as fluid flow - water hammer, and fluid oscillation must all be carefully understood.
But maybe you just want to make a model of a Beaver dam!
What is bad about the Snowy Hydro scheme?
There were numerous benefits to the Snowy Mountains Hydroelectric Scheme, but there were certainly some problems. One of the major problems was the fact that many people were displaced from homes their families had owned for generations when towns like Old Adaminaby were drowned with the building of the dam and the filling of Lake Eucumbene. Houses we're relocated to higher ground, but many lost their livelihood. Because of the importance of the Scheme, and the need to keep the waters of Lake Eucumbene crystal clear, stock was no longer permitted to be run in that area of the High Country. These people, especially the property owners who ran stock, did not necessarily have skills that could be used in conjunction with the Snowy Mountains Hydroelectric Scheme, so they had to relocate, often without ever finding gainful employment again.
Why is hydro power better than other renewable sources of power?
Hydro power (electricity created by directing water from waterfalls, dams, tidal systems or waves) is a simple way for creating power. It usually requires the installation of a turbine in the water flow which extracts the energy to use a dynamo.
The process creates few pollutants but can cause the emission of methane from plants submerged during the construction of the lake behind dams. These same dams can prevent the return of spawning fish, and destroy land based ecosystems.
Whether hydro power is better than solar, wind and geothermal power is a matter of opinion. They are all valuable. They are all expensive to set up, but are clean and pollution free after that.
