So this thing from Intel can transmit 60 watts over 3 feet at 75% efficiency.

Not bad, but not great either, if you want to transmit power over distances. So at 4 feet, it could only transmit 33.75 watts. At 10 feet, it can only transmit 5.4 watts. That's just the nature of the inverse cube law.

What this technology will be useful for: Imagine you have a mat sitting on your desk at home. You can just set your cell phone phone, MP3 player, and laptop on it and they will charge without having to hook up any wires.

What this technology will not be useful for: Transmitting powers to whole homes or businesses from the generating station.

Kinda like the way a train works, but wireless, i like it.

Its about time someone start using Tesla's technology. The world could benefit from
N. Tesla if only the the goverment would not have surpresed his devices the public.

When Intel makes this more practical, this technology will be as large as the home computer. The implications of being able to recharge a power source without wires will be amazing. As long as I'm not frying myself in the process.

What would be FAR more useful is what I call PowerUSB. A concept like it is in the drawers at several large and small consumer electronic companies, but they are unable to come up with a single standard.
The Vision developed by a now defunct highend hifi company was this
2x 230V/16A power, grounded
combined with an ultra high Bandwidth Version of USB, something in the High gigabit Range.
All in one squarish cable that would be only ~50% thicker than our current power cables.
The benefit (an example)
1 Cable from Power outlet to Computer
1 Cable from Computer to TV
1 Cable from TV to Cable/Sat/Receiver
1 Cable from Receiver to Sourround Amp
etc etc and all could communicate with each other. You practically have one thread of wire that connects all the devices in a room or even in a house/apptmnt.

Instead of 10 bazillion cables interconnecting between all those causing a HUGE CHAOS in my ROOM, GOD its SO ABOUT TIME FOR THIS!!!!!

HDMI is only a very small step in the right direction.

this wireless transmission of electricity is pretty cool. I imagine the conversion of radio stations and and every house and car being equipped with a little black box that receives the energy and coverts it into electricity. The box could send out a monthly signal that the power station receives that ells how much power it's consumed for the month and a bill could be sent. don't pay your bill they transmit a kill switch signal to the box and it shuts down until the power company turns it back on. sorta like your cable bill.

I often wonder that if Intel is now disclosing this tech that they are working on if the military hasn't already developed and deployed this tech.

I imagine the tech would be really useful for nuclear submarines. reactors are quite but running off of nothing but batteries is even quieter I'd imagine. I could picture a towable wire that picks up this transmission of energy, probably a very low frequency antenna. A base somewhere around the planet could have an antenna that broadcasts this energy transmission subs could receive this signal and convert it to electricity running their motors with out the use of reactors. Might only be useful when traveling at lower speeds but I could see where the military could find this sort of tech useful.

I haven't read any of the responses yet, just the title, allow me to say simply this: If they are just introducing this to the commercial market now, imagine what the black contingent has already; Hyper Monorails beneath the earth? Anti-gravity technology? Zero-point energy? Seriously, if they hold the secret to the latter, and haven't shared it amongst their brethren, let them be reduced to naught but a shrubbery!


Ni!

I can't see how sending energy wireless can not have a negative effect on organic life. Look at cellphones, the little energy that those radio waves carry is dangerous for your brain. But hey maybe they found a way that won't cook your insides

I saw a post about Tesla putting a globe at the top of antennas.

Below the globe was the spiral coil that upped voltage winding to
winding. The center wire went up to the globe.

People think its a balloon holding up the wire for the antenna.

Take a look at the Tesla Tower, its half of a globe.
The antenna top matches the shape of the earth.

Any statics class gives the two globe example and dynamically
should send out father reaching signals than a straight wire.

THe top of the antennas are mushroom shaped like half of a sphere. Very interesting. DOes the coil or part of the antenna have to be sphere like to mimic earths shape? does this make the field more resonant with the earth or help it to propagate farther because of the shape?

Very interesting indeed. I am going to look out for other antenna like things that have that distinctive shape. maybe the military has the use of this technology and have incorporated it into some systems. maybe an antenna that has the half dome top of it obscured in some way to mask it from curious eyes.

Tesla was the inventor of AC which is why we have electrical power as we know it today. Edison was about DC (battery power) which is unable to transmit efficiently over distances of more than a few hundred feet.

Tesla though not given the credit had also discovered the principals of the radio. Marconi only applied them to communcations.

The first radios were called "Wireless Sets" and radios and televisions are sending low power energy through the air similarly to what Intel is demonstrating here. Instead of powering a radio/television receiver it is powering a light bulb.


Tesla was shutdown by the Oil powers because he was close to revealing his discovery of free energy from the earth with it's magnetic core and a rotating dielectric charged atmosphere (air)in essence a huge coil.
Similar in principal to how the energy of lightning is generated which is millions of joules of energy.

Teslas coils with their dome shape were so shaped to increase the amount of surface area exposed to the atmosphere (of the generated charge) and thereby increasing the amount of energy transmitted.

I don't agree with this at all. Our airwaves are already full of dangerous invisible radiation already. Is this what they do when they hit the battery technology barrier? Just think of the cell phones, radio, television, CB/HAM, wireless networks, microwave and countless others already filling the airwaves. Were already more tired, fat and sickly than 30 years ago and our generation is dying off much younger. I wonder if in 20 years will look back and see how foolish we were?
