War of Currents In the War of Currents era (sometimes, War of the Currents or Battle of Currents) in the late 1880s, George Westinghouse and Thomas Edison became adversaries due to Edison's promotion of direct current (DC) for electric power distribution over alternating current (AC). Thomas Edison, American inventor and businessman, known as "The Wizard of Menlo Park", pushed for the development of a DC power network. George Westinghouse, American entrepreneur and engineer, financially backed the development of a practical AC power network. Edison's direct-current system generated and distributed electric power at the same voltage as used by the customer's lamps and motors. This meant that the current in transmission was relatively large, and so heavy conductors were required and transmission distances were limited, to about a mile (kilometre); otherwise transmission losses would make the system uneconomical. At the time, no method was practical for changing voltages of DC power.

Nikola Tesla Nikola Tesla (Serbian Cyrillic: Никола Тесла; 10 July 1856 – 7 January 1943) was a Serbian American[2][3][4][5] inventor, electrical engineer, mechanical engineer, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system.[6] Tesla gained experience in telephony and electrical engineering before immigrating to the United States in 1884 to work for Thomas Edison in New York City. He soon struck out on his own with financial backers, setting up laboratories and companies to develop a range of electrical devices. His patented AC induction motor and transformer were licensed by George Westinghouse, who also hired Tesla for a short time as a consultant.

University of Cambridge Language Centre Overview This is a web-application developed by the University of Cambridge Language Centre for basic level students of German. It focuses on listening and reading skill but it also includes many activities that help learners prepare for speaking and writing. 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.

Tesla coil A Tesla coil is an electrical resonant transformer circuit invented by Nikola Tesla around 1891.[1] It is used to produce high-voltage, low-current, high frequency alternating-current electricity.[2][3][4][5][6][7][8] Tesla coils can produce higher voltages than electrostatic machines,[citation needed] 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.

German Words and Phrases 1. Basic Phrases Ich is not actually pronounced ikh, unless you are speaking a northern dialect of German. If you are speaking a southern dialect, then it is more like ish. There is no equivalent sound in English. 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.[1][2] One of Tesla’s desires for implementation of this turbine was for geothermal power, which was described in "Our Future Motive Power".[3] Description[edit]

Introduction Introduction German is an easy language for native English speakers to learn. Both languages are Western (meaning Germanic) languages, so they have many similarities. English and German both use the Roman alphabet and have many words that are similar. This is because many English words were derived from German words. German grammar and sentence structure also shares some similarities with English.

Plasma globe A plasma globe with filaments extending from the inner sphere to the outer. Description[edit] 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.

Savo said that Tesla took him to Buffalo, New York in 1931 and showed him a modified Pierce-Arrow automobile. This story has received some debate for the fact that the car's propulsion system is said to have been invented by Tesla. No physical evidence has ever been produced confirming that the car actually existed.
