Wireless energy transfer The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. Other methods under consideration are electromagnetic radiation in the form of microwaves or lasers and electrical conduction through natural media. Electric energy transfer An electric current flowing through a conductor, such as a wire, carries electrical energy. When an electric current passes through a circuit there is an electric field in the dielectric surrounding the conductor; magnetic field lines around the conductor and lines of electric force radially about the conductor. In a direct current circuit, if the current is continuous, the fields are constant; there is a condition of stress in the space surrounding the conductor, which represents stored electric and magnetic energy, just as a compressed spring or a moving mass represents stored energy.

The Missing Secrets of Nikola Tesla The Secret Life of Nikola Tesla « Revolutionizing Awareness Posted by Admin on June 16, 2010 by Nikola Tesla Suppose some one should discover a new mechanical principle–something as fundamental as James Watt’s discovery of the expansive power of steam—by the use of which it became possible to build a motor that would give ten horse power for every pound of the engine’s weight, a motor so simple that the veriest novice in mechanics could construct it and so elemental that it could not possibly get out of repair. Then suppose that this motor could be run forward or backward at will, that it could be used as either an engine or a pump, that it cost almost nothing to build as compared with any other known form of engine, that it utilized a larger percentage of the available power than any existing machine, and, finally, that it would operate with gas, steam, compressed air or water, any one of them, as its driving power. It does not take a mechanical expert to imagine the limitless possibilities of such an engine. Read the rest of this entry »
Nikola Tesla: The Genius Who Lit the World This is the documentary film about Nikola Tesla, the scientist and inventor, one of the greatest men in history. Nikola Tesla was born on July 10,1856 in Smiljan, Lika in what later became Yugoslavia. His father, Milutin Tesla was a Serbian orthodox priest and his mother Djuka Mandic was an inventor in her own right of household appliances. Before going to America, Tesla joined Continental Edison Company in Paris where he designed dynamos. Young Nikola Tesla came to the United States in 1884. Direct current flows continuously in one direction; alternating current changes direction 50 or 60 times per second, and can be stepped up to very high voltage levels, minimizing power loss across great distances. Tesla's A-C induction motor is widely used throughout the world in industry and household appliances. Watch the full documentary now
Why Nikola Tesla was the greatest geek who ever lived Additional notes from the author: If you want to learn more about Tesla, I highly recommend reading Tesla: Man Out of Time Also, this Badass of the week by Ben Thompson is what originally inspired me to write a comic about Tesla. Ben's also got a book out which is packed full of awesome. There's an old movie from the 80s on Netflix Instant Queue right now about Tesla: The Secret of Nikola Tesla. It's corny and full of bad acting, but it paints a fairly accurate depiction of his life. The drunk history of Tesla is quite awesome, too. History.com has a great article about Edison and how his douchebaggery had a chokehold on American cinema.
Tesla coil A Tesla coil is an electrical resonant transformer circuit invented by Nikola Tesla around 1891. It is used to produce high-voltage, low-current, high frequency alternating-current electricity. Tesla coils can produce higher voltages than electrostatic machines, which are another source of artificial high-voltage discharges. Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits. Tesla used these coils to conduct innovative experiments in electrical lighting, phosphorescence, X-ray generation, high frequency alternating current phenomena, electrotherapy, and the transmission of electrical energy without wires. Theory A Tesla coil transformer operates in a significantly different fashion from a conventional (i.e., iron core) transformer. History The later and higher-power coil design has a single-layer primary and secondary. 1902 design
Recovered The Ten Inventions of Nikola Tesla Which Changed The W Nikola Tesla-Did You Know? “Tesla was considered an eccentric man who talked of death rays that could destroy 10,000 airplanes at a distance of 250 miles. However, Tesla devised the AC (alternating current) system that we use in our homes today. AC offered great advantages over the rival DC system. By using Tesla’s transformers, AC voltages could be stepped up (or down) and transmitted over long distances through thin wires. At the 1893 World Exposition in Chicago, Tesla demonstrated the safety AC electricity was by passing high frequency AC power through his body to power light bulbs. By 1898, he was demonstrating to the world the first remote controlled model boat at Madison Square Garden. Nikola Tesla was born at midnight on July 9, 1856 in Smiljan, Lika, Croatia. “…the idea occurred to me like a flash of lightning and in a second the truth revealed itself. He was talking about an alternating current (AC) induction motor. “For a long time nothing happened…” he said. 1. 2. 3. 4. 5. 6.
System of Transmission of Electrical Energy SPECIFICATION forming part of Letters Patent No. 645,576, dated March 20, 1900. Application filed September 2, 1897. Serial No. 650,343. To all whom it may concern: Be it known that I, NIKOLA TESLA, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful improvements in Systems of Transmission of Electrical Energy, of which the following is a specification, reference being had to the drawing accompanying and forming a part of the same. It has been well known heretofore that by rarefying the air inclosed in a vessel its insulating properties are impaired to such an extent that it becomes what may be considered as a true conductor, although one of admittedly very high resistance. Referring to the drawing, A is a coil, generally of many turns and of a very large diameter, wound in spiral form either about a magnetic core or not, as may be found necessary.
Tesla's Egg of Columbus World's Fair: Columbian Exposition Tesla presentation, 1893 Nikola Tesla, at the 1893 World's Columbian Exposition, demonstrated a device he constructed known as the "Egg of Columbus." It was used to demonstrate and explain the principles of the rotating magnetic field model and the induction motor. Tesla's Egg of Columbus performed the feat of Columbus with a copper egg in a rotating magnetic field. Tesla's device used a toroidal iron core stator on which four electromagnetic coils were wound.

Brain Pickings | Education 07 APRIL, 2014By: Maria Popova “It’s insulting to imply that only a system of rewards and punishments can keep you a decent human being.” Isaac Asimov was an extraordinary mind and spirit — the author of more than 400 science and science fiction books and a tireless advocate of space exploration, he also took great joy in the humanities (and once annotated Lord Byron’s epic poem “Don Juan”), championed humanism over religion, and celebrated the human spirit itself (he even wrote young Carl Sagan fan mail). Like many of the best science fiction writers, he was as exceptional at predicting the future as he was at illuminating some of the most timeless predicaments of the human condition. In a 1988 interview with Bill Moyers, found in Bill Moyers: A World of Ideas (public library) — the same remarkable tome that gave us philosopher Martha Nussbaum on how to live with our human fragility — Asimov explores several subjects that still stir enormous cultural concern and friction.
Tesla turbine Tesla turbine The Tesla turbine is a bladeless centripetal flow turbine patented by Nikola Tesla in 1913. It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine. The Tesla turbine is also known as the boundary layer turbine, cohesion-type turbine, and Prandtl layer turbine (after Ludwig Prandtl). Bioengineering researchers have referred to it as a multiple disk centrifugal pump. One of Tesla’s desires for implementation of this turbine was for geothermal power, which was described in "Our Future Motive Power". Description View of Tesla turbine "bladeless" design Tesla wrote, "This turbine is an efficient self-starting prime mover which may be operated as a steam or mixed fluid turbine at will, without changes in construction and is on this account very convenient. This turbine can also be successfully applied to condensing plants operating with high vacuum. Pump Tesla Other
Nikola Tesla Nikola Tesla (Serbian Cyrillic: Никола Тесла; 10 July 1856 – 7 January 1943) was a Serbian-American inventor, electrical engineer, mechanical engineer, physicist, and futurist who is best known for his contributions to the design of the modern alternating current (AC) electricity supply system. Born and raised in the Austrian Empire, Tesla received an advanced education in engineering and physics in the 1870s and gained practical experience in the early 1880s working in telephony and at Continental Edison in the new electric power industry. He emigrated to the United States in 1884, where he would become a naturalized citizen. He worked for a short time at the Edison Machine Works in New York City before he struck out on his own. Attempting to develop inventions he could patent and market, Tesla conducted a range of experiments with mechanical oscillators/generators, electrical discharge tubes, and early X-ray imaging.

Tesla Coils: Unleash the Aether Nikola Tesla's most significant contribution was not AC power, radio, or the induction motor, but what we call the Tesla Coil - a tool which allows for the power of the aether to be unleashed and harnessed. Now being launched through an open source project. by Hank MillsPure Energy Systems News The inventions of Nikola Tesla are numerous. He invented radio, teleautomatics (remote control technology), poly-phase alternating current, the induction motor, and many other innovations that established the foundation for our modern civilization. There are many misconceptions about Tesla coils and their intended use. Tesla coils have capabilities beyond even the highest voltage transformers of our day, because they are something far different. Radiant Blasts When an electrical switch in an electrical circuit is opened or closed, a spark of high voltage can be created. In his lab, Tesla would utilize a dynamo to produce very quick pulses of high voltage direct current. Safety Enhancements
Plasma globe A plasma globe with filaments extending from the inner sphere to the outer. Description The effect of a conducting object (such as a hand) in close proximity with the plasma globe glass Some globes have a control knob that varies the amount of power going to the center electrode. At the very lowest setting that will light or "strike" the globe, a single tendril is made. This single tendril's plasma channel engages enough space to transmit this lowest striking energy to the outside world through the glass of the globe. Placing a finger tip on the glass creates an attractive spot for the energy to flow, because the conductive human body (having non-ohmic resistance of about 1000 ohms at room temperature) is more easily polarized than the dielectric material around the electrode (i.e. the gas within the globe) providing an alternative discharge path having less resistance. Much of the movement of the filaments is due to heating of the gas around the filament. History In U.S.
