Electricity had been known about since greeks and Benjamin Franklin had shown the relationship between lightning and electricity. But, it was Michael Faraday with his research into electromagnetism and later invention of the Electric Dynamo in 1831 which really opened up the way to the practical use of electricity. Although it would be Nikola Tesla almost 60 years later that showed the use of Alternating current using alternators and not Direct Current to be the best for wide spread transmission of electricity. Almost a revolutionary as the generation of the electrical power, the light bulb brought light the world, at any time any were. Before its invention, people had to rely on oil lamps and then gas but both of these had considerable drawbacks with low light output and above all safety as they both relied on burning oil or gas. But the introducing of electric lamp changed these completely. 28 years later coldwater canyon tribute to TD by Frank Dorittke is licensed under a Creative Commons Attribution licence (http://creativecommons.org/licenses/b...)
