Veebeam wirelessly transmits computer content to your TV
By Paul Ridden

If you're looking for an affordable way to stream high definition online movies to a big screen TV, then Veebeam could just be what you're looking for. The device comes in both standard and high definition varieties, and is made up of a wireless USB antenna that's connected to a laptop or computer and a receiver box that's hooked up to an HDTV.

The system is said to be capable of wirelessly playing any content from one to the other, whether it's online movies, sports or news updates, digital photos or holiday videos.

Veebeam is described by its creators as being content agnostic, meaning that it will wirelessly stream anything from your laptop or computer to your TV. Rather than use a set-top box or bottlenecking an already overworked wireless home network, the Veebeam system creates a point-to-point, 150Mb/s wireless connection between the USB Antenna and the receiver unit. Not quite the potential offered by a Wireless-N connection, but at least this one promises constant rate.

The receiver is of course plugged into the television and incorporates ST Microelectronics' advanced HD decoding IC running Wyplay's embedded digital media renderer software. Users can choose between the screencasting mode, that offers the best experience for viewing photos or websites, and the higher-quality Play-To mode, which allows for multi-tasking as well as benefiting from the highest video output.

There are two varieties on offer – the Veebeam SD edition costs US$99 and has an output resolution of 480i and Dolby Digital audio, and the Veebeam HD variety at US$139, which has the same composite A/V outputs as its sibling but also includes full 1080p resolution output via HDMI port, optical audio output and a couple of USB ports.

I wonder when the day will come when one can transmit electrical energy such as 220Vac wirelessly.

Then we can iron clothes without that pesky cord in the way. Or tons of copper behind yr PC for yr PC, speakers etc.

hahah...sorry sir.........fundamental physics say this is not possible.
Energy can neither be created nor destroyed....
So everything is just transformation of one type of energy to another......

Why not? teleportation of energy ..vibration in one place induced in another ..

seriously it is not possible.....pse don't go there..

Anyway I did a quick check on teleportation in wikipedia:

Teleportation is the transfer of matter from one point to another, more or less instantaneously. Teleportation is used widely in works of science fiction and fantasy.

All of you are wrong. No need teleportation or break the law of energy conservation.

Nicola Tesla already provided a solution to transfer electricity wirelessly and on an industrial scale.

Only problem was that it short out an entire town as well.

The basis of the idea is to convert electricity into a magnetic wave and have a receiver that would resonate to the pulses and generate electricity at the other end.

You would find small scale units such as these in wireless phone charger kiosks at your neighbourhood malls.

From wikipedia:

"Tesla stated one of the requirements of the World Wireless System was the construction of resonant receivers.[17] The related concepts and methods are part of his wireless transmission system (US1119732 — Apparatus for Transmitting Electrical Energy — 1902 January 18). Tesla made a proposal that there needed to be many more than thirty transmission-reception stations worldwide.[18] In one form of receiving circuit the two input terminals are connected each to a mechanical pulse-width modulation device adapted to reverse polarity at predetermined intervals of time and charge a capacitor.[19] This form of Tesla system receiver has means for commutating the current impulses in the charging circuit so as to render them suitable for charging the storage device, a device for closing the receiving-circuit, and means for causing the receiver to be operated by the energy accumulated.[20]"

And by the way, if not for Tesla being sponsored by Westinghouse to commercialise AC, we would all be using Thomas Edison's DC from electrical powerpoints.

Scientists break into new ground, but it takes a lot more effort of many than proving a theory to create practical applications.

QXD, Wireless charging is a close proximity process.
Induction charging. Like a transformer..Primary / Secondary.

Power received drops logarithmically as distance between the coils increase.

Yes, Tesla proposed the concept.
But it is not clear how power can be transmitted over long distance efficiently.

Just to elaborate a bit more:

theory of flight is known for hundreds of years...
in fundamental physics, it is simply you have a wing shaped so that air travels longer above than below, it will create lift effects. the difficulty is in getting enough power to lift off in the first place.
hence the advance of diesel engines and propellers allow us to make a flying machine....further advances are with jet engines (higher power to weight ratio) and composite materials (lighter); etc but the fundamental flight principle is still the same.....

for transmitting high power wireless over long distance, the fundamental is still the same.....transformation of one energy form to another.
u see jet engines, rockets; etc and think they have amplified the power....the answer is no, they all abide by the law of fundamental physics (Newton's Law) which is transformation of one form of energy to another with varying degree of losses (heat; etc) thrown in.....that is another fundamental thing, in all tranformation there will be losses.

hahaha...uncle botak.....good at least u know the fundamentals....
this 1 i guess 1......
u can alter flights direction (left/right) by the rudders at the tail
and up/down by the air flaps on the wings
so by adjusting them in the correct way, you can fly upside down

Birds can't fly upside down because their flights are powered by their wings that flap one way only. Airplanes can fly upside down because their flights are powered by engines with wings as aerodynamic gliding balance only. However, except for acrobatics or dogfight manoevres, airplanes don't fly upside because it's tough on the pilots and passengers. On the machine itself, it's no problem.
