LONDON (AFP) - Scientists have discovered a ground-breaking way of levitating ultra small objects, which may revolutionise the design of micro-machines, a new report says.

Physicists said they can create "incredible levitation effects" by manipulating so-called Casimir force, which normally causes objects to stick together by quantum force.

The phenomenon could be used to improve the performances of everyday devices ranging from car airbags to computer chips, say Professor Ulf Leonhardt and Dr Thomas Philbin from Saint Andrews University.

Casimir force -- discovered in 1948 and first measured in 1997 -- can be seen in a gecko's ability to stick to a surface with just one toe.

Now the British scientists say they can reverse the Casimir force to cause an object to repel rather than attract another in a vacuum.

"The Casimir force is the ultimate cause of friction in the nano world, in particular in some micro-electromechanical systems," said Leonhardt, writing in the August issue of New Journal of Physics.

"Micro or nano machines could run smoother and with less or no friction at all if one can manipulate the force," he added.

And he added: "In order to reduce friction in the nanoworld, turning nature's stickiness into repulsion could be the ultimate remedy. Instead of sticking together, parts of micromachinery would levitate."

Leonhardt stressed that the practise is possible only for micro-objects.

But he underlined that, although in principle it may one day be possible to levitate humans, that day is a long way off.

"At the moment, in practice it is only going to be possible for micro-objects with the current technology, since this quantum force is small and acts only at short ranges," he said.

"For now, human levitation remains the subject of cartoons, fairytales and tales of the paranormal."

Their research was to be published in the New Journal of Physics.

BUILD YOUR OWN LEVITATING CRAFT USING STUFF AT HOME

It's very simple, watch the following and find out how.

More info to second video;

The Lifter works without moving parts, flies silently, uses only electrical energy and is able to lift its own weight plus an additional payload. The Lifter uses the Biefeld-Brown effect discovered by Thomas Townsend Brown in 1928. The basic design of the Lifter has been fully described in the Townsend Brown US Patent N°2949550 filed on Aug 16, 1960 and titled "Elektrokinetic Apparatus", you will find in this patent the full description of the main principle used in the Lifter devices.

Today, more than 350 Lifter replications have been done successfully by many experimenters and physicists Worldwide ( see The Worldwide Lifters replications logbook ).

On January 22th, 2003, I have fully demonstrated with the 250 g weight Lifter "Maximus ][" experiment, that a Lifter can be scaled up and also that such a device is able to lift 60 g of payload. It is now possible to build a VTOL craft which will use the Biefeld-Brown effect to fly silently and without moving parts ( see VTOL Lifter-Craft Mk III ) only powered by electrical energy...
