Shop What is Wind Energy? People have been tapping the power of wind for thousands of years to power windmills and drive sailboats. Without the power of wind, there would be no history of great explorers like Christopher Columbus, Vasco Nunez de Balboa, and John Cabot who voyaged across oceans and seas to explore the wonders of the world. Also, our ancestors would have struggled to travel across seas and oceans to trade with other nations.
Of all the endless variety of phenomena which nature presents to our senses, there is none that fills our minds with greater wonder than that inconceivably complex movement which, in its entirety, we designate as human life; Its mysterious origin is veiled in the forever impenetrable mist of the past, its character is rendered incomprehensible by its infinite intricacy, and its destination is hidden in the unfathomable depths of the future.
Whence does it come? Whither does it tend? The sun is the past, the earth is the present, the moon is the future. From an incandescent mass we have originated, and into a frozen mass we shall turn. Merciless is the law of nature, and rapidly and irresistibly we are drawn to our doom.
Lord Kelvin, in his profound meditations, allows us only a short span of life, something like six million years, after which time the suns bright light will have ceased to shine, and its life giving heat will have ebbed away, and our own earth will be a lump of ice, hurrying on through the eternal night.
But do not let us despair. There will still be left upon it a glimmering spark of life, and there will be a chance to kindle a new fire on some distant star. This wonderful possibility seems, indeed, to exist, judging from Electricity generation using a wind turbine essay Dewar's beautiful experiments with liquid air, which show that germs of organic life are not destroyed by cold, no matter how intense; consequently they may be transmitted through the interstellar space.
Meanwhile the cheering lights of science and art, ever increasing in intensity, illuminate our path, and marvels they disclose, and the enjoyments they offer, make us measurably forgetful of the gloomy future. Though we may never be able to comprehend human life, we know certainly that it is a movement, of whatever nature it be.
The existence of movement unavoidably implies a body which is being moved and a force which is moving it. Hence, wherever there is life, there is a mass moved by a force. All mass possesses inertia, all force tends to persist. Owing to this universal property and condition, a body, be it at rest or in motion, tends to remain in the same state, and a force, manifesting itself anywhere and through whatever cause, produces an equivalent opposing force, and as an absolute necessity of this it follows that every movement in nature must be rhythmical.
Long ago this simple truth was clearly pointed out by Herbert Spencerwho arrived at it through a somewhat different process of reasoning.
Does not the whole of human life attest to it? Birth, growth, old age, and death of an individual, family, race, or nation, what is it all but a rhythm? All life-manifestation, then, even in its most intricate form, as exemplified in man, however involved and inscrutable, is only a movement, to which the same general laws of movement which govern throughout the physical universe must be applicable.
Colorado Springs Notes, pagePhotograph X. The electrical pressure, alternating one hundred thousand times per second, excites the normally inert nitrogen, causing it to combine with the oxygen. The flame-like discharge shown in the photograph measures sixty-five feet across.
When we speak of man, we have a conception of humanity as a whole, and before applying scientific methods to, the investigation of his movement we must accept this as a physical fact. But can anyone doubt to-day that all the millions of individuals and all the innumerable types and characters constitute an entity, a unit?
Though free to think and act, we are held together, like the stars in the firmament, with ties inseparable. These ties cannot be seen, but we can feel them. I cut myself in the finger, and it pains me: I see a friend hurt, and it hurts me, too: And now I see stricken down an enemy, a lump of matter which, of all the lumps of matter in the universe, I care least for, and it still grieves me.
Does this not prove that each of us is only part of a whole? For ages this idea has been proclaimed in the consummately wise teachings of religion, probably not alone as a means of insuring peace and harmony among men, but as a deeply founded truth.
The Buddhist expresses it in one way, the Christian in another, but both say the same: We are all one. Metaphysical proofs are, however, not the only ones which we are able to bring forth in support of this idea.
Science, too, recognizes this connectedness of separate individuals, though not quite in the same sense as it admits that the suns, planets, and moons of a constellation are one body, and there can be no doubt that it will be experimentally confirmed in times to come, when our means and methods for investigating psychical and other states and phenomena shall have been brought to great perfection.
The individual is ephemeral, races and nations come and pass away, but man remains. Therein lies the profound difference between the individual and the whole.
Therein, too, is to be found the partial explanation of many of those marvelous phenomena of heredity which are the result of countless centuries of feeble but persistent influence. Conceive, then, man as a mass urged on by a force. Though this movement is not of a translatory character, implying change of place, yet the general laws of mechanical movement are applicable to it, and the energy associated with this mass can be measured, in accordance with well-known principles, by half the product of the mass with the square of a certain velocity.
So, for instance, a cannon-ball which is at rest possesses a certain amount of energy in the form of heat, which we measure in a similar way.Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity.
The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity. Wind turbines, like windmills, are usually mounted on a tower to capture the most energy. Building power plants is only the first step to generating success. Running plants efficiently, and consistently improving efficiency as they run, is the path to putting profits on the bottom line.
Almost all offshore wind farms currently use fixed platforms built into the seafloor. While they are increasingly common in Europe, they are just starting in the US, partly due to public opposition.
Sep 06, · The sun is the ultimate source of energy for our planet. Its energy is found in fossil fuels as well as all living things. Harnessing its energy holds great promise for the world’s energy needs, and it will be heavily called upon as fossil fuels are depleted.
Nov 20, · AOA, A couple of days back, I was required to make a presentation on Energy Crisis in Pakistan and its consequences. Though it was in form of powerpoint presentation, yet I initially made an essay of.
Electricity generation is the process of creating electricity from other forms of energy.
The fundamental principles of electricity generation were discovered during the s and early s by the British scientist Michael Faraday.
