The Nikola Tesla electric car anecdote refers to a supposed invention described by Peter Savo, who claimed to be a nephew of Nikola Tesla.
According to the story, in 1931, Tesla modified a Pierce-Arrow car in Buffalo, New York by removing the gasoline engine and replacing it with a brushless AC electric motor. The motor was purportedly powered by a "cosmic energy power receiver" contained in a box measuring 25 inches by 10 inches by 6 inches, which contained 12 radio vacuum tubes and was connected to a 6-foot-long antenna. The car was claimed to have been driven for about 50 miles at speeds of up to 90 mph over an eight-day period. [1] [2]
The story has been subject to debate due to the lack of physical evidence to confirm both the existence of the car and the fact that Tesla did not have a nephew named Peter Savo. Tesla's grand-nephew, William Terbo, has also dismissed the Tesla electric car story as a fabrication.[ citation needed ]
A number of web pages exist that perpetuate this anecdote. [3] [4] The continuous recycling of reactive power is a method by which the car could have been powered, [5] [6] though there is a lack of verifiable evidence contemporaneous to the story. If the car was powered (for the most part) by the reuse of reactive power, a thorough review of these anecdotes would be required to determine if an extremely high quality factor is responsible for significantly offsetting power losses. [7]
With the exception of these points, every other account of this purported demonstration automobile is based solely on the Peter Savo story with additional embellishments added by subsequent retellings. [8] [9] [10] [11] [12] [13]
Nikola Tesla was a Serbian-American inventor, electrical engineer, mechanical engineer, and futurist. He is known for his contributions to the design of the modern alternating current (AC) electricity supply system.
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates in reverse, converting mechanical energy into electrical energy.
A compressed-air car is a compressed-air vehicle powered by pressure vessels filled with compressed air. It is propelled by the release and expansion of the air within a motor adapted to compressed air. The car might be powered solely by air, or combined with other fuels such as gasoline, diesel, or an electric plant with regenerative braking.
Wireless power transfer (WPT), wireless power transmission, wireless energy transmission (WET), or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that transmits power across space to a receiver device; the receiver device extracts power from the field and supplies it to an electrical load. The technology of wireless power transmission can eliminate the use of the wires and batteries, thereby increasing the mobility, convenience, and safety of an electronic device for all users. Wireless power transfer is useful to power electrical devices where interconnecting wires are inconvenient, hazardous, or are not possible.
Free energy suppression is a conspiracy theory that technologically viable, pollution-free, no-cost energy sources are being suppressed by governments, corporations, or advocacy groups. Devices allegedly suppressed include perpetual motion machines, cold fusion generators, torus-based generators, reverse-engineered extraterrestrial technology, anti-gravity propulsion systems, and other generally unproven, low-cost energy sources.
A plasma ball, plasma globe, or plasma lamp is a clear glass container filled with noble gases, usually a mixture of neon, krypton, and xenon, that has a high-voltage electrode in the center of the container. When voltage is applied, a plasma is formed within the container. Plasma filaments extend from the inner electrode to the outer glass insulator, giving the appearance of multiple constant beams of colored light. Plasma balls were popular as novelty items in the 1980s.
A green vehicle, clean vehicle, eco-friendly vehicle or environmentally friendly vehicle is a road motor vehicle that produces less harmful impacts to the environment than comparable conventional internal combustion engine vehicles running on gasoline or diesel, or one that uses certain alternative fuels. Presently, in some countries the term is used for any vehicle complying or surpassing the more stringent European emission standards, or California's zero-emissions vehicle standards, or the low-carbon fuel standards enacted in several countries.
The Tesla Experimental Station was a laboratory in Colorado Springs, Colorado, USA built in 1899 by inventor Nikola Tesla and for his study of the use of high-voltage, high-frequency electricity in wireless power transmission. Tesla used it for only one year, until 1900, and it was torn down in 1904 to pay his outstanding debts.
Vehicle-to-grid (V2G) describes a system in which plug-in electric vehicles (PEV) sell demand response services to the grid. Demand services are either delivering electricity or reducing their charging rate. Demand services reduce pressure on the grid, which might otherwise experience disruption from load variations. Vehicle-to-load (V2L) and Vehicle-to-vehicle (V2V) are related, but the AC phase is not sychronised with the grid, so the power is only available to an "off grid" load.
Hermann Plauson was an Estonian professor, engineer and inventor. Plauson investigated, among other things, the production of power based on atmospheric electricity.
The Tesla Roadster is a battery electric vehicle sports car, based on the Lotus Elise chassis, produced by Tesla Motors from 2008 to 2012. The Roadster was the first highway legal, serial production, all-electric car to use lithium-ion battery cells, and the first production all-electric car to travel more than 244 miles (393 km) per charge. It is also the first production car to be launched into deep space, carried by a Falcon Heavy rocket in a test flight on February 6, 2018.
An alternative fuel vehicle is a motor vehicle that runs on alternative fuel rather than traditional petroleum fuels. The term also refers to any technology powering an engine that does not solely involve petroleum. Because of a combination of factors, such as environmental and health concerns including climate change and air pollution, high oil-prices and the potential for peak oil, development of cleaner alternative fuels and advanced power systems for vehicles has become a high priority for many governments and vehicle manufacturers around the world.
Colorado Springs Notes, 1899–1900 (ISBN 8617073527) is a book compiled and edited by Aleksandar Marinčić and Vojin Popović detailing the work of Nikola Tesla at his experimental station in Colorado Springs at the turn of the 20th century.
Ceravision is a privately owned lighting company based in Milton Keynes, UK. Ceravision is the inventor of High Efficiency Plasma (HEP) lighting technology, a new and unique genre of electrodeless lamps, driven by radio frequency (RF) and particularly suited to medium and high power commercial applications.
Resonant inductive coupling or magnetic phase synchronous coupling is a phenomenon with inductive coupling in which the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates. A resonant transformer of this type is often used in analog circuitry as a bandpass filter. Resonant inductive coupling is also used in wireless power systems for portable computers, phones, and vehicles.
A plug-in electric vehicle (PEV) is any road vehicle that can utilize an external source of electricity to store electrical energy within its onboard rechargeable battery packs, to power an electric motor and help propelling the wheels. PEV is a subset of electric vehicles, and includes all-electric/battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). Sales of the first series production plug-in electric vehicles began in December 2008 with the introduction of the plug-in hybrid BYD F3DM, and then with the all-electric Mitsubishi i-MiEV in July 2009, but global retail sales only gained traction after the introduction of the mass production all-electric Nissan Leaf and the plug-in hybrid Chevrolet Volt in December 2010.
The World Wireless System was a turn of the 20th century proposed telecommunications and electrical power delivery system designed by inventor Nikola Tesla based on his theories of using Earth and its atmosphere as electrical conductors. He claimed this system would allow for "the transmission of electric energy without wires" on a global scale as well as point-to-point wireless telecommunications and broadcasting. He made public statements citing two related methods to accomplish this from the mid-1890s on. By the end of 1900 he had convinced banker J. P. Morgan to finance construction of a wireless station based on his ideas intended to transmit messages across the Atlantic to England and to ships at sea. His decision to change the design to include wireless power transmission to better compete with Guglielmo Marconi's new radio based telegraph system was met with Morgan's refusal to fund the changes. The project was abandoned in 1906, never to become operational.
Nikola Tesla patented the Tesla coil circuit on April 25, 1891. and first publicly demonstrated it May 20, 1891 in his lecture "Experiments with Alternate Currents of Very High Frequency and Their Application to Methods of Artificial Illumination" before the American Institute of Electrical Engineers at Columbia College, New York. Although Tesla patented many similar circuits during this period, this was the first that contained all the elements of the Tesla coil: high voltage primary transformer, capacitor, spark gap, and air core "oscillation transformer".
A new, and improved, primary zinc battery capable of powering an electric vehicle for a range of 500 miles before easily and economically replacing its cathode (negative terminal) plates by the car's owner from a year's supply of fresh, new plates which could easily be stored within the trunk of the car.
Tesla states that he made numerous statements in publications in regards to using electricity to power a car. Tracking down these statements should dispel the myth that his car was powered by radiant energy.
Higher power efficiency values are reached also by converting the speaker's reactive energy (BACK-EMF) into usable power and storing it in the condensers. This technology not only increases the efficiency of the amplifier, it also protect the loudspeaker from overheating by removing the reactive energy.
Various embodiments may achieve one or more advantages. For example, some embodiments may improve a system efficiency and/or reduce the cost of energy consumption by returning some energy back to an input source, for example, in the form of an assisting torque that reduces the average torque load on a prime mover.
While tracking down a scam artist who disappeared with 200 million dollars, a freelance insurance investigator stumbles across an online video by the leader of a group called the Free Energy Coalition. She suspects the man in the video is her missing suspect and goes to a Free Energy conference to find out, but is quickly sucked into the murky world of conspiracy theories which claim the laws of thermodynamics have been faked to prevent the world from discovering perpetual motion machines which can generate free energy.
