The Coalbrookdale Company produced the "Kyrle Grate", invented by Parker; it was an open grate in which anthracite coal could be burnt. It was awarded a silver medal at the Smoke Abatement Exhibition in 1881. [4] [1] Parker worked on improvements on the lead-acid battery invented by Gaston Planté. He took out a patent in 1882, which coincided ...
In 1828, Ányos Jedlik, a Hungarian who invented an early electric motor, constructed a tiny model car powered by his new motor. [8] In 1834, Vermont blacksmith Thomas Davenport, the inventor of the first American DC electric motor, installed his motor in a small model car, which he operated on a short circular electrified track.

Paper capacitor manufacturing started. 1876: Russian engineer Pavel Yablochkov invented the electric carbon arc lamp. 1876: Scottish inventor Alexander Graham Bell patented the telephone. 1877: American inventor Thomas Edison invented the phonograph. 1877: German industrialist Werner von Siemens developed a primitive loudspeaker. 1878
In 1866, Georges Leclanché invented a battery that consists of a zinc anode and a manganese dioxide cathode wrapped in a porous material, dipped in a jar of ammonium chloride solution. The manganese dioxide cathode has a little carbon mixed into it as well, which improves conductivity and absorption. [10] It provided a voltage of 1.4 volts. [11]
1859 - Gaston Planté invented the lead–acid battery, the first-ever battery that could be recharged by passing a reverse current through it. 1860 - first urban horse railway line (a predecessor of trams), opened in Saint Petersburg. [24] 1862 – Étienne Lenoir made a gasoline engine automobile.
1816 – Robert Stirling invented his hot air Stirling engine, and what we now call a "regenerator". [5] [6] 1821 – Michael Faraday builds an electricity-powered motor. 1824 – Nicolas Léonard Sadi Carnot first publishes that the efficiency of a heat engine depends on the temperature difference between an engine and its environment.
William Powell Lear (June 26, 1902 – May 14, 1978) was an American inventor and businessman. He is best known for founding Learjet, a manufacturer of business jets.He also invented the battery eliminator for the B battery, and developed the car radio and the 8-track cartridge, an audio tape system.

A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
