MIT Scientists Show How To Light A Bulb Wirelessly

Posted June 08, 2007 3:56 PM

From TechWeb:

The team from MIT announced the light bulb breakthrough this week and called the concept "WiTricity," for wireless electricity. MIT scientists have been able to wirelessly light a 60-watt light bulb from a source seven feet away, and the experimenters believe it demonstrates -- at least theoretically -- that consumer electronics devices like laptops and cell phones one day could be charged without wires. The theory isn't new -- Nicola Tesla wrote about it more than a century ago -- but with millions of electronics devices needing constant recharging, the necessity as mother of invention may finally be at hand. Even so, it likely will be years before consumers will be able to rid themselves of the electrical wires proliferating around their phones and computers.

Nikola Tesla, (with a K) according to anything I've ever read, did not just write about it. He did it. He lit up light bulbs at a distance of 26 miles. This wasn't just a fairy tale. You may as well say that the technology was well developed and theorized over a century ago, and these people are hoping to put a new spin on it, and spend more taxpayer dollars without actually doing anything.

I'm not impressed.

Agreed; First thing I thought of when I saw this title was "Tesla did that 100 years ago." Everyone knows he was ahead of his time but I didn't think that the bright minds at MIT would completely neglect the fact that he ever existed or did any work in the first place.

The way these things go, it isn't the scientists ignoring significant facts, or being misinformed, but that the media has goals other than jounalism for publishing crap.

Regardless of why, it is probably more the media, and a significant lack of journalistic integrity that is responsbible for this. Also, Thomas Edison, Tesla's nemesis is partly responsible for the obscurity of Tesla.

Not really - He's the reason that some of Tesla's ideas are in our homes and used around the world today. He just erased Tesla's name and signed his own in the process... Thieving Schmuck.

I haven't done any research on what I'm about to say (lame? sure, but it's Saturday) but isn't it possible that the "26-mile away" method demonstrated 100 years ago worked but was not safe or efficient? If it was so easy to do, why hasn't someone else developed it yet? Why be so quick to judge?

I think because there isn't a convenient way to charge for the energy, as you may not know whose lightbulbs are getting lit up. I'm quick to judge for exactly the reasons you don't want to hear about. I might be the guy cornering you at the party..lol

Another tidbit is that Tesla lit up some 200 light bulbs at 26 miles, but also caused a major shutdown at the local colorado powerstation while doing it.. that didn't go over very well, even though they were happy to have him experimenting (He Was news back then) so in the end, it may have been seemed "Out of Control", and therefore unsafe. who knows.

I've discovered how to light that bulb more efficiently, and at any distance. Run two wires and make a direct connection. Shhhh. We might get some grant money for it.

Let's cut the pie in half: use one wire.

Connect the other side to a capacitor which is grounded which is connected to the earth.

Now you can dim the bulb by changing the frequency, so easy.

That sounds like the amazing new way to get TV channels without wires, right through the air! (As seen on TV, in an ad for better "rabbit ears" antennas.)
