(CNN) -- Katie Hall was shocked the second she saw it: a light-bulb glowing in middle of a room with no wires attached.

Looking back, it was a crude experiment, she remembers: a tiny room filled with gigantic cooper refrigerator coils -- the kind you'd see if you cracked open the back of your freezer.

She walked in and out between the coils and the bulb -- and still the bulb glowed.

"I said: 'Let's work on this. This is the future.'"

2. Very cool, but hopw will we keep people from stealing the

wireless energy?
I love the idea of not having to trip over extension cords any longer.

11. Why do you think everything is wired today?

It was a fight between Tesla and Edison, and TPTB & the monied interests of the Gilded Age made sure Tesla lost.

9. See Tesla v Edison video below

Tesla invented wireless transmission of electricity decades ago. Also alternating current so people and animals didn't get routinely fried as with Edison's direct current.

12. New Book Called "Topsy: The Startling Story of the Crooked Tailed Elephant"

Edison electrocuted an elephant using alternating current (and poison) to make it appear too dangerous.

In 1903, on Coney Island, an elephant named Topsy was electrocuted, and over the past century, this bizarre, ghoulish execution has reverberated through popular culture with the whiff of urban legend. But it really happened, and many historical forces conspired to bring Topsy, Thomas Edison, and those 6600 volts of alternating current together that day.
