MIT Wirelessly Powers a Lightbulb

kcurtis writes "According to the Boston Globe, MIT Researchers have powered a light bulb remotely. The successful experiment lit a 60-watt light bulb from a power source two meters away, with no physical connection between the power source and the light bulb. Details about WiTricity, or wireless electricity, are scheduled to be reported today in Science Express, the advance online publication of the journal Science, the Massachusetts Institute of Technology said. 'The team from MIT is not the first group to suggest wireless energy transfer. Nineteenth-century physicist and engineer Nikola Tesla experimented with long-range wireless energy transfer, but his most ambitious attempt - the 29m high aerial known as Wardenclyffe Tower, in New York - failed when he ran out of money. Others have worked on highly directional mechanisms of energy transfer such as lasers. However, unlike the MIT work, these require an uninterrupted line of sight, and are therefore not good for powering objects around the home.'"

      This rivals the invention of the cordless lightsaber. Luke Skywalker used to lose a LOT of battles until he ditched that awful extension cord. Kept getting his feet tangled up. And Count Doofus would laugh as he yanked on it and watched Luke fall on his ass. Also, sometimes opponents would pull the plug out of the wall socket and snicker at Luke's bewilderment. Yoda would just smack his head and say "Duh-oh! The Force is not especially smart in this young one! Save up for Duracell adapter, he must."

    About ten years ago, my dad came home from work and told me about a practical joke someone had played at work.

    Some engineers had called the technician, complaining that the light in their office wouldn't turn off. The technician came, and no, it didn't turn the bulb off. He attached the multimeter to the switch... the power was being turned on and off by the switch. He attached it to the bulb itself... power was being cut. So he removed the bulb: it stayed on even when unplugged.

    The engineers had pointed an active magnetron at the bulb.

    First off, Nicola Tesla was not insane. Secondly, he *did* do this, many times in fact.


    Just because Tesla was a genius doesn't mean he wasn't also insane. He invented a great many useful and wonderful things that are very important to the infrastructure of modern society, and was at times denied credit by jealous and antagonistic rivals, but he had many eccentricities, particularly in his later life, that point to him not having been entirely well in the head. He refused to eat where others could see him, freaked out about other people's hair touching him, and generally seems to have had serious problems maintaining normal interpersonal relationships with other people.
