“I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success. …” (Nikola Tesla, 1856 – 1943)
This is big news, folks! Nikola Tesla’s concept of broadcast power is upon us. An MIT assistant professor, Marin Soljacic (pronounced SOLE-ya-cheech) who is also a 2008 MacArthur genius-grant winner, is already powering up electronic devices by sending electrons through the air. W00t! I am some happy about this. I first heard about Tesla and broadcast power 40 years ago. Yes, I’ve been a Tesla fan for almost as long as I’ve been a Brian Wilson fan, and — hey! — I only had to wait 35 years to hear Brian play “Smile” in concert. And now, here comes Marin Soljacic from Croatia, my dream country, to make Tesla’s dream come true.
So it’s cause for celebration. Let’s imagine a world without power cords. A life with free-range computers. Coke machines that work even out in the middle of a field. Cell phones that don’t need to be recharged. Electric coffee pots out on the beach for that early morning buzz. Need some electricity? Scoop it up from the air.
I love it, I do. Possibilities are endless. And, no, I don’t want to hear the down side. Let me glow on this one for a bit, please.
Wireless Electricity Is Here (Seriously)
By: Paul Hochman
I’m standing next to a Croatian-born American genius in a half-empty office in Watertown, Massachusetts, and I’m about to be fried to a crisp. Or I’m about to witness the greatest advance in electrical science in a hundred years. Maybe both.
Either way, all I can think of is my electrician, Billy Sullivan. Sullivan has 11 tattoos and a voice marinated in Jack Daniels. During my recent home renovation, he roared at me when I got too close to his open electrical panel: “I’m the Juice Man!” he shouted. “Stay the hell away from my juice!”
He was right. Only gods mess with electrons. Only a fool would shoot them into the air. And yet, I’m in a conference room with a scientist who is going to let 120 volts fly out of the wall, on purpose.
“Don’t worry,” says the MIT assistant professor and a 2008 MacArthur genius-grant winner, Marin Soljacic (pronounced SOLE-ya-cheech), who designed the box he’s about to turn on. “You will be okay.”
We both shift our gaze to an unplugged Toshiba television set sitting 5 feet away on a folding table. He’s got to be kidding: There is no power cord attached to it. It’s off. Dark. Silent. “You ready?” he asks.
If Soljacic is correct — if his free-range electrons can power up this untethered TV from across a room — he will have performed a feat of physics so subtle and so profound it could change the world. It could also make him a billionaire. I hold my breath and cover my crotch. Soljacic flips the switch.
Soljacic isn’t the first man to try to power distant electronic devices by sending electrons through the air. He isn’t even the first man from the Balkans to try. Most agree that Serbian inventor Nikola Tesla, who went on to father many of the inventions that define the modern electronic era, was the first to let electrons off their leash, in 1890.
Tesla based his wireless electricity idea on a concept known as electromagnetic induction, which was discovered by Michael Faraday in 1831 and holds that electric current flowing through one wire can induce current to flow in another wire, nearby. To illustrate that principle, Tesla built two huge “World Power” towers that would broadcast current into the American air, to be received remotely by electrical devices around the globe.
Few believed it could work. And to be fair to the doubters, it didn’t, exactly. When Tesla first switched on his 200-foot-tall, 1,000,000-volt Colorado Springs tower, 130-foot-long bolts of electricity shot out of it, sparks leaped up at the toes of passersby, and the grass around the lab glowed blue. It was too much, too soon.
But strap on your rubber boots; Tesla’s dream has come true. After more than 100 years of dashed hopes, several companies are coming to market with technologies that can safely transmit power through the air — a breakthrough that portends the literal and figurative untethering of our electronic age. Until this development, after all, the phrase “mobile electronics” has been a lie: How portable is your laptop if it has to feed every four hours, like an embryo, through a cord? How mobile is your phone if it shuts down after too long away from a plug? And how flexible is your business if your production area can’t shift because you can’t move the ceiling lights?
The world is about to be cured of its attachment disorder.
