I think this is the same story I blogged May 10 which is making the rounds again…
A new aircraft has been designed with no moving parts. It is powered by magnetohydrodynamics, the force created when a current or a magnetic field is passed through a conducting fluid.
Flying saucers may soon be more fact than mere science fiction. University of Florida mechanical and aerospace engineering associate professor Subrata Roy has submitted a patent application for a circular, spinning aircraft design reminiscent of the spaceships seen in countless Hollywood films. Roy, however, calls his design a “wingless electromagnetic air vehicle,” or WEAV.
The proposed prototype is small – the aircraft will measure less than six inches across – and will be efficient enough to be powered by on-board batteries.
Roy said the design can be scaled up and theoretically should work in a much larger form. Even in miniature, though, the design has many uses.
The most obvious functions would be surveillance and navigation. The aircraft could be designed to carry a camera and light and be controlled remotely at great distances, he said.
… the conducting fluid will be created by electrodes that cover each of the vehicle’s surfaces and ionize the surrounding air into plasma. The force created by passing an electrical current through this plasma pushes around the surrounding air, and that swirling air creates lift and momentum and provides stability against wind gusts. … – sd
This may actually be ancient technology rediscovered. This or similar technology may have been secretly in use for many years and may account for some UFO sightings.
In the Manusa, the most elaborate details for building aerial machines are set down. The Samarangana Sutradhara says that they were made of light material, with a strong, well-shaped body. Iron, copper, mercury and lead were used in their construction. They could fly to great distances and were propelled through air by motors. The Samarangana Sutradhara text devotes 230 stanzas to the building of these machines, and their uses in peace and war:
Strong and durable must the body be made, like a great flying bird, of light material. Inside it one must place the Mercury-engine with its iron heating apparatus beneath. By means of the power latent in the mercury which sets the driving whirlwind in motion, a man sitting inside may travel a great distance in the sky in a most marvelous manner. Similarly by using the prescribed processes one can build a vimana as large as the temple of the God-in-motion. Four strong mercury containers must be built into the interior structure. When these have been heated by controlled fire from iron containers, the vimana develops thunder-power through the mercury. And at once it becomes a pearl in the sky. Moreover, if this iron engine with properly welded joints be filled with mercury, and the fire be conducted to the upper part it develops power with the roar of a lion. – fa
