Tesla Proven Right as Technology is Transmitted Wirelessly

CW June 8, 2007 38

Scientists at the Massachusetts Institute of Technology (MIT) Cambridge, US, have managed to light a 60-watt light bulb from an energy source seven feet away. They hope the system can be adapted to charge mobile phones, MP3 players, laptops and other appliances. The technology is being dubbed “WiTricity” by the scientists.

Nicola Tesla demonstrated the potential over 100 years ago, in Colorado Springs in 1899 by lighting 200 light bulbs – from 26 miles away.

The new approach involves two coils joined by an invisible resonating magnetic field with one coil attached to a power source acting as a sender unite, the field resonates with a receiver coil.

One coil attached to a power source acts as a sender unit and the field resonates with a receiver coil, inducing a current to flow through it.

Professor Peter Fisher, who helped to conduct the research said: “As long as the laptop is in a room equipped with a source of such wireless power, it would charge automatically, without having to be plugged in. In fact, it would not even need a battery to operate inside of such a room.”

A light bulb was lit in a Laurel and Hardy Movie made about 1936. As a child my Father demonstrated the method using a Diathermy. Separate the pads and hold the bulb between them. More power for greater distance, such as one pad in the ceiling and another under a wooden table top. Flip the switch Radio Waves-Heat, hold bulb in hand or mouth, easy….Don't over do it. A Diathermy is a Medical Instrument used for deep heating the body, and requires a Prescription.

well of course Tesla was right. He was [i]NIKOLA FUCKING TESLA[/i].

I remember lighting a fluorescent bulb with a Tesla coil in Physics2 in college. The problem was never in the transfer, it was in making sure nobody was hurt and that the fields were correctly perpendicular.

Just some engineering food for thought. And "WiTricity" sounds terrible.

the hand remote for a dogs shock colar will light up a physics bulb to. at 3 ft away

The problem with this concept is energy loss. A great deal of energy is used to create a magnetic field, and only a small portion of that is returned to electric potential in a battery. The net effect is to greatly increase the cost to run a product and in exchange you get.. no cord. Hardly worth the trade, don't you think?

This will be broadened into space travel. Becuase it doesn;t seem feasible on the ground in todays world. Sending WiTricity through the air all over the place? Something about that sounds dangerous.

But, we can launch some satellites out their with big solar panels. Boom, charging stations for any vehicles we want to launch where ever. Much better then carrying all sorts of liquid fuel for launch, travel, and return. Possibly setup a wider and wider infrastructure in space to aid further and further exploration. Something like that….

Also yes, this isn't a new technology at all. Tesla was right all along, and everybody already knew that. There's also already a device that charges your portable gadgets just by laying them on the "charging pad". So I'm asking, why are these chumps in Mass. wasting their time? Learn something ya bastards!
JTK

They know more than most, Jeremy. When you double the distance between emitter and receiver you get 1/4 of the energy. That means this is useless over any long distance and even at short ranges it has huge energy loss. This may have application, but hardly anything world changing.

And yet, Tesla was able to transmit sufficient power from a 100 kilowatt generator at Spring Falls, to light 200, 150watt light bulbs, from a distance of 26 miles.

However he did it, it clearly didn't obey the inverse square law.
J

Silicon.shaman, To put 3kW over 26 miles doesn't mean the 100kW original field Tesla used disobeyed the inverse square law. It's still 97% loss.

Inverse square law is not 1/(r^2), it's k/(r^2). If you play around with k (voltage or field shape), it shouldn't be impossible – just dangerous to stand next to. Oh and yes, the shape of the transformer can make a difference.

@ Jon

When you match Nikola Tesla in the number of patents tendered I will validate your fears. Until then get back to studying.

Can anybody do Nikola's experiment 26 miles away with 200 bulbs I think not.
Ed

It's sad, when Tesla did this back then, they just thought of him as a clever magician… Unfortunately this could have come in handy in today's world.

Fuck edison. Fucking thug.

Fuck westinghouse. Tesla set up an entire house that drew energy from the earth and the atmosphere…showed it to westinghouse, who said,"How do we charge them for this electricity?" Tesla replied,"CHARGE them? This should be free…for everyone!"

Westinghouse,"You're fired."
bnt

What's new about induction heating? It's what boils pots on your glass-top cooking range.

Frankly, I don't believe ANYBODY lit 200 lightbulbs wirelessly from 26 miles range in 1899.

Apart from urban myths, can anyone point me to an authenticated record of that electromagnetic pulse event?

With the amount of power lines strewn about our modern world, you can guarantee that Teslas' secret to absorbing waste energy has been buried very deep by the government and the energy businesses. Free power for life to whoever can figure it out.

I am sure Tesla could have used a focused energy stream at the point of origin and a satellite-type receiver at the destination, just like modern wi-fi or satellites work. Most satellites transmit waves over 26,200 Miles. Makes only 26 Miles look kinda sad, but for back then it would have been amazing.

It’s not the 26,200 miles that’s hard. It’s just the first (or last) 10. The troposphere.

the earth is a magnet, the sun is a magnet, fields, field strengths and field orientations, polarizations, are known, measurable, calculable, e.g. magvar, a simple compass needle. Tesla understood orientation and magnetism, and their compatibilities and correspondences within electromagnetism. he "thoughtfully" independently (opinion)invented superconductor theory, and understood dielectric potentials between "gaps" in the "aether". capacitor charge and discharge rates, – and + electron flow, wireless power transfers via earth to sky to earth (lighting)mediums. tesla believed in the aether — because he could calculate the effects, but could not observe/measure them. so the effects were nameless… aether.

our science is meant to explore how to improve the efficiency of the machines we build that "WORK" for US. tesla science, while known, will be used to fuel the minds and machines that work for everyone.

Good comment, FOT.

There's something of an awakening taking in place in cosmology right now which gives great hope of hoiking us all out of the realms of pure math back into the practical arena of physics.

Tesla, sure but also Birkland, Alfven and, er possibly Hutchison [;-)

Depends: how much energy do you think Tesla used in his experiment? At a distance of 26 miles the falloff would have been IMMENSE, so looking at just producing WiTricity in a local area…if someone could figure out what Tesla did, that is.

I love that Nikola Tesla did this in the 1800s with 200 lightbulbs, 27 miles away, and we can light one bulb from 7 feet away and it's a huge breakthrough. Why didn't he just write it down?!
pooponastick

its all a transfer of energy and waves. MIT needs to think outside the box like the guy that made an aluminum foil "plane" that rides on ionic updrafts (or whatever, he only has theories of why it works.) he built this in his garage, without a team of MIT majors. and it was all based on teslas idea of an infrastructure of electronic lines that could be used to power and supply lift for vehicle used in public transportation. Now, build a deathray, i want 2.

@bnt: But we aren't talking about /anybody/, we're talking about /Nikola Fucking Tesla/. http://www.badassoftheweek.com/tesla.html

@yourmother: Write it down? Why bother? From what I've read, he had a photographic memory, and could do all the calculations and designs in his head. He didn't need to, so why bother?
Chris

One light bulb seven feet away, Tesla lit 200 bulbs from 26 miles away in 1899 from spare parts in the dessert. This is a "Tony Stark built it in cave" moment. Of course Tesla really managed it, you only fake things when you lack the ability to pull it off for real.

Also “WiTricity”…..really? Tesla is already building a machine to fry you from beyond the grave.
HavensFire

Who came up with "WiTricity?" Stupidest name I've ever heard of.

@bnt, Although the same idea of induction heating, the applications are what make it completely different. Intentionally using energy loss as heat is simple. Keeping that energy loss to a minimum, over distances, and using it for charge separation… not THAT'S difficult.

Good job, MIT. Now, if only we could actually figure out how Tesla did HALF of all he's done, we'd be very well off! Personally, I'd love to live in that house and not have to pay for electricity!

A guy in australia already made a generator that produces around 5x the energy that goes in. He used magnets, gravity and something else. He gets a nice check at the end of each month from the electric company. He also is trying to make it so it will work with cars… as you can imagine the oil companies were offering a load of cash to buy his invention. Everything is so hush hush nowadays, you would probably never hear of anything exciting in the field of free energy; unless someone went to great lengths to anger every oil driven politician in the world… Assassination on the spot.

Nikola Tesla invented the fluorescent tubes a hundred years ago, but his invention has only recently become popular because of energy saving. Many do not know that he invented the fluorescent tubes.
