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).

Alfred Louis Bernardin, Sr., who founded the Bernardin Bottle Cap Company in Evansville, Indiana (1881), started the first manufacture of metal closures in not only the U.S., but in the world. \n\nSince Mr. Bernardin, a wine importer experienced trouble with corks blowing out in ocean shipments, he devised a metal clamp to fit over the cork and down around the neck of the bottle with a metal strap that tightened the clamp and prevented the cork from blowing out. Later, Mr. Bernardin invented many other types of metal closures for glass containers that are still popular and in current usage. He invented the beer cap, or crown cap, for beer and soft drink bottles. \n\nHe later manufactured METAL SCREW  CAPS and still later experimented with applying colored lacquers and enamels to these caps before they were fabricated from sheet form. Others of his inventions were the first double shell cap, first cap to be used on catsup bottles, and many types of machines for the manufacturing and applying of these closures. \n\nhttp://www.bullworks.net/daily/04feb08.htm

In 1910 Dr. Walter O. Snelling, a chemist and explosives expert for the U.S. Bureau of Mines, was contacted to investigate vapors coming from a gasoline tank vent of a newly purchased Ford Model T. Dr. Snelling filled a glass jug with the gasoline from the Ford Model T and discovered on his way back to the lab that volatile vapors were forming in the jug, causing its cork to repeatedly pop out. He began experimenting with these vaporous gases to find methods to control and hold them. After dividing the gas into its liquid and gaseous components, he learned that propane was one component of the liquefied gas mixture. He soon learned that this propane component could be used for lighting, metal cutting and cooking.\n\nThat discovery marked the birth of the propane industry.

The ancient Greeks and Parthians knew of static electricity from rubbing objects against fur.\n\nIn modern times  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). The late 19th and early 20th century produced such giants of electrical engineering as Nikola Tesla, Samuel Morse, Antonio Meucci, Thomas Edison, George Westinghouse, Werner von Siemens, Charles Steinmetz, and Alexander Graham Bell.\nclick here please:http://en.wikipedia.org/wiki/History_of_electricity
