However, humanity has much to thank for ideas such as alternating current, electric motor (used by washing machines or computers), radio, remote control, fluorescent or energy-efficient light bulbs.

- Patent more than 1000 inventions.
- To improve the quality of life and the industry of its era through inventions such as: the long-lasting electric bulb, the phonograph (which allowed to record and reproduce sounds) or the kinetoscope (precursor of the cinematographic projector); among others.]]> 2018-05-23 15:02:42 UTC https://padlet.com/jmelsion/bkkipxapvlzk/wish/263057379 jmelsion https://padlet.com/jmelsion/bkkipxapvlzk/wish/263060511 After the presentation of the Edison lamp, the new electric lighting systems became the most important technological achievement in the world. In addition, electricity could substitute steam to operate the motors.
Main problem: the transport of energy based on direct current over long distances was very expensive.]]> 2018-05-23 15:10:42 UTC https://padlet.com/jmelsion/bkkipxapvlzk/wish/263060511 jmelsion https://padlet.com/jmelsion/bkkipxapvlzk/wish/263061337 Tesla was convinced that alternating current was a better solution. The AC, unlike the DC, can raise the voltage with a transformer which facilitates transport over long distances with little loss in the form of heat and once the electricity reaches its destination, the power plants, before supplying the Energy to customers, reduce the voltage to safe levels.]]> 2018-05-23 15:12:43 UTC https://padlet.com/jmelsion/bkkipxapvlzk/wish/263061337 jmelsion https://padlet.com/jmelsion/bkkipxapvlzk/wish/263063886 Edison, threatened by the emergence of Tesla's technology, confronts him in a public relations battle, which newspapers called "the war of the currents," to determine which system would become the dominant technology. Edison electrocuted dogs, cats and even an elephant to prove that alternating current was dangerous. To neutralize this initiative, Tesla was exposed to a CA that went through his body without causing him any harm. After this test, Edison could not do anything and his prestige was eroded.]]> 2018-05-23 15:19:25 UTC https://padlet.com/jmelsion/bkkipxapvlzk/wish/263063886
