He was a Serbian-American inventor, physicist, mechanical engineer and electrical engineer. Tesla is recognized among the most accomplished scientists of the late 19th and early 20th century. His patents and theoretical work form the basis of modern alternating current electric power (AC) systems, including the polyphase power distribution system and AC motor, with which he helped usher in the Second Industrial Revolution.

I assume you were refering to Nicoli Tesla. Indeed he was great man. I read a book about him several years ago. It was he that invented alternating current. The credit usually goes to george westinghouse, and he does indeed deserve partial credit-he financed Mr. Tesla.\n\nTesla invented many things that are in use today. Of course A.C. was the big one. There are other reasons why tesla is not so famous. His main rival was Tom Edison. Tom Edison was also a inventor (duh) and his idea of using D.C. was the one to beat. Tesla's A.C. was superior and edison knew it, but Edison had a huge ego and did stunts trying to show that A.C. was dangerous. Basicaly he electrocuted animals on stage. If you look hard on the internet you will find a very old video of edison electrocuting an elephant to death. \n\nWhat it all boils down to is Westinghouse and Edison hating each other and that is what the public saw, and poor old tesla was just plain forgotten about.

If you think about the properties of electromagnetism and electricity itself, and you study up on Teslas ideas, it seems as if there is a whole new area of science waiting to be seen by the mainstream. It is not complicated at all and should be looked into.

This was the dream of Nikola Tesla.\nNikola Tesla (Smiljan, near Gospic, Austrian Empire (now Croatia), July 10, 1856 – c. January 7, 1943 in New York) was a Serbian-American inventor, physicist, mechanical engineer and electrical engineer.\n\nHis nationality is disputed between Croatians and Serbs. Tesla himself said that he was equally proud of his Serbian heritage as of his Croatian homeland [1].\n\nTesla is recognized among the most accomplished scientists of the late 19th and early 20th centuries. His patents and theoretical work form the basis of modern alternating current electric power (AC) systems, including the polyphase power distribution systems and AC motor, with which he contributed to the Second Industrial Revolution.\n\nIn the United States, Tesla's fame rivaled that of any other inventor or scientist in history or in popular culture. After his demonstration of wireless communication in 1893 and after being the victor in the "War of Currents", he was widely respected as America's greatest electrical engineer. Much of his early work pioneered modern electrical engineering and many of his discoveries were of groundbreaking importance. Never putting a large focus on his finances, Tesla died impoverished and forgotten at the age of 86. In his later years, Tesla was regarded as a mad scientist and became noted for making bizarre claims about possible scientific developments\n\nWireless energy transfer, by definition, does not require a physical medium through which to flow. Anyone can demonstrate that energy can be transmitted without a direct physical connection by simply touching the ends of a wire, briefly, to the ends of a small battery. Hold the wire near a compass needle while you do this and you'll see the compass needle twitch. It takes energy to make something move, so you've transmitted energy wirelessly. The needle moves because the electric current which briefly flows through the wire generates a magnetic field which acts on the needle (see electromagnetic induction and magnetic field for more information).\n\nAnother, more dramatic demonstration of wireless energy uses a radio transmitter generating more than a few watts, such as an amateur radio transmitter. A Fluorescent lamp with no wires attached to it, held near the antenna, will glow when the transmitter is activated. Send "SOS" and the light blinks "SOS". The transmitted energy causes the gas inside the lamp to glow, like the northern lights.\n\nOnce the basic principle is established, then the problem is to concentrate the energy of the transmission so that most of it is received where it can be converted into useful power. Think of a flashlight that lets you focus the light beam or spread it out so that it's very wide. If you wanted to shine the flashlight on a solar cell, you'd want the flashlight's beam to be tightly focussed to reduce the amount of energy which does not fall on the receiver and is lost.\n\nEarly systems (such as Tesla proposed) were incapable of such "focusing" of transmitted energy, because the necessary antenna size is impractically large at low frequencies (see extremely low frequency radio waves). Without focusing, much of the energy would be lost to the atmosphere.\n\nThe advent of technology for much higher transmission frequencies (such as those used by microwave transmitters) created the possibility of "beaming" the energy through the use of directional antennas, such as the one invented by Hidetsugu Yagi. Lasers, which create a coherent and tightly "beamed" form of light energy, are even more appropriate.\n\nIn most cases the cost of such solutions is much higher than simply using copper wire. Wireless energy transfer, then, is most interesting for applications where the energy receiver can't be copper-tethered to the energy source — such as sending energy to an airplane or spacecraft, or another planet, or in the case of

When you ask the question "Who invented electric power?", I presume you mean the electric power distribution that we know of today.\n\nOne of the primary contributors would be Nikola Tesla, a Serbian-American electrical engineer and scientist.  He along with the Westinghouse corporation developed the three-phase AC power distribution used around the world today.  Tesla and Westinghouse corp were also heavily involved in developing new generators and motors using three-phase power.  Edison was trying to promote a relatively inefficient DC distribution system at the same time, but failed to gain widespread support.  Though Edison did create inventions, such as the light bulb, that helped make use of the ever-growing power grid.\n\nI had not heard of Gennai Hiraga before, but sounds like a pretty interesting inventor as well.

Thomas Alva Edison did not invent Electricity. \n\nThomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman who developed many devices which greatly influenced life in the 20th century. \nHe was one of the first inventors to apply the principles of mass production to the process of invention, and can therefore be credited with the creation of the first industrial research laboratory.\n\nHistory of electricity - \n\nThe ancient Greeks and Parthians knew of static electricity from rubbing objects against fur.\n\nThough Benjamin Franklin's famous "invention" of electricity by flying a kite in a thunderstorm turned out to be more fiction than fact, his theories on the relationship between lightning and static electricity sparked the interest of later scientists whose work provided the basis for modern electrical technology. Most notably these include Luigi Galvani (1737–1798), Alessandro Volta (1745-1827), Michael Faraday (1791–1867), André-Marie Ampère (1775–1836), and Georg Simon Ohm (1789-1854).

It annoys me that you can't just look up his invention plans anymore online. In the last 5 years information on him has been dissapearing and other websites want money for it.\n\nI think the U.S. government owns a fair few of his patents and likes to keep tesla's work secret

Look up Tesla Coils on the internet, but be VERY careful with these devices. They are high voltage but a cool science fair project.
