"The first electric streetcar. Invented by Stockbridge, Mass. -born engineer Stephen Dudley Field, 28, it is the first car anywhere to be run successfully with current generated by a stationary dynamo: one wheel picks up current carried by one of the rails.

Nikola Tesla's development of alternating current motors made possible the invention of oscillating fans in the early 20th century. And in 1902, a 25-year-old engineer from New York named Willis Carrier invented the first modern air-conditioning system.

The birth of the electric vehicle And while Robert Anderson, a British inventor, developed the first crude electric carriage around this same time, it wasn't until the second half of the 19th century that French and English inventors built some of the first practical electric cars.

Joshua Lionel Cowen (/ˈkoʊən/; August 25, 1877 – September 8, 1965) was an American inventor and the co-founder of Lionel Corporation, a manufacturer of model railroads and toy trains. Cowen also invented the flash-lamp in 1899, an early photographer's flash light source.

This system had been invented by Holroyd Smith, an engineer from Halifax, which used a conduit in the road, between the two rails, to carry the electricity.

However, as with a lot of inventions, the first inventor was not the one who made the device practical. In 1873, Zenobe Gramme, a Belgian inventor, invented the first commercially practical (one which could be made reliably and cheaply enough to sell commercially) electric motor.

In 1852, in New York, Elisha Otis pioneered the safety lift, which ensured the cab wouldn't fall if the cable snapped. The Equitable Life Building, in New York, was the first in the world to have passenger lifts in in 1870, and the first electric lift was invented in 1880 by Werner von Siemens in Germany.

British chemist Humphrey Davy is credited with inventing the arc lamp. In 1809, he connected two wires to a battery, and used charcoal strips as electrodes.

Robert Davidson (1804–1894) was a Scottish inventor who built the first known electric locomotive in 1837. He was a lifelong resident of Aberdeen, northeast Scotland, where he was a prosperous chemist and dyer, amongst other ventures.

Many people think that Les Paul was the inventor of the electric guitar, but he wasn't. The credit for this goes to George Beauchamp, a musician, and Adolph Rickenbacker, an electrical engineer, who are rightfully considered to be the people who created the first commercially viable modern amplifiable electric guitar.

However, supply to the lamps was intermittent and in 1882 Thomas Edison and his company, The Edison Electric Light Company, developed the first steam-powered electric power station on Pearl Street in New York City. The Pearl Street Station initially powered around 3,000 lamps for 59 customers.

The first electrically operated typewriter, consisting of a printing wheel, was invented by Thomas A. Edison in 1872 and later developed into the ticker-tape printer. The electric typewriter as an office writing machine was pioneered by James Smathers in 1920.

The first electric circuit was invented by Alessandro Volta in 1800. He discovered he could produce a steady flow of electricity using bowls of salt solution connected by metal strips.

Records show that Louis Goldenberg, invented the electric washing machine in the late 1800s and early 1900s. 1908, Alva J. Fisher created an electric washing machine. It's generally considered that he is the inventor of the first electric washing machine.

1.) 1834 - Thomas Davenport of Vermont developed the first real electric motor ('real' meaning powerful enough to do a task) although Joseph Henry and Michael Faraday created early motion devices using electromagnetic fields. The early "motors" created spinning disks or levers that rocked back and forth.

The effect had been known since the early 1800s, when scientists started building the first large batteries and noticed that electric current jumped across a gap in a circuit from one electrode to another, producing a brilliant light in the process. British chemist Humphrey Davy is credited with inventing the arc lamp.

John Stevens is considered to be the father of American railroads. In 1826 Stevens demonstrated the feasibility of steam locomotion on a circular experimental track constructed on his estate in Hoboken, New Jersey, three years before George Stephenson perfected a practical steam locomotive in England.
