Why do ufos spin
Gases such as air, which has an equal number of positive and negative charges become plasma when energy such as heat or electricity causes some of the gas's atoms to lose their negatively charged electrons, creating atoms with a positive charge, or positive ions, surrounded by the newly detached electrons.
Using an onboard source of energy such as a battery, ultracapacitor , solar panel or any combination thereof , the electrodes will send an electrical current into the plasma, causing the plasma to push against the neutral noncharged air surrounding the craft, theoretically generating enough force for liftoff and movement in different directions depending on where on the craft's surface you direct the electrical current.
The concept sounds far-fetched, but U. At six inches Theoretically, Roy says, the flying saucer can be as large as anyone wants to build it, because the design gives the aircraft balance and stability. In other words, this type of aircraft could someday be built large enough to ferry around people.
But, Roy says, "we need to walk before we can run, so we're starting small. Roy is not sure what kind of energy source he will use yet. He anticipates that the craft's body will be made from a material that is an insulator such as ceramic, which is light and a good conductor of electricity. The choice of a power source that is powerful, yet lightweight is "probably going to be the thing that makes or breaks it.
Roy began designing the WEAV in The balloons were inadvertently released at 1 p. The planet Venus often gets mistaken for a UFO. To viewers on Earth, the second planet from the sun appears as a bright light that hangs in the sunset sky, seeming to slowly hover in the twilight as it outshines every star except for the sun. Because Venus orbits the sun inside our own orbit, from our perspective it constantly darts out on the either side of the sun, which people often mistake for a moving UFO.
Was the Star of Bethlehem Actually Venus? Here's proof that anything funny-looking in the sky can cause an uproar. This past Monday, most of the U. The sightings were spurred by video of a condensation trail, or contrail, streaking through clouds lit up by the rising sun. After a thorough investigation, many experts now believe that the streak was a wait for it a run-of-the-mill jet aircraft contrail that happened to hang around longer than usual.
Contrails appear most vivid around sunrise or sunset, and it's not uncommon that one showing up in an unexpected location will generate whispers of a UFO or experimental military aircraft.

The fans are distributed across the wing span or Using aluminum particles and fresh or waste , the technology could one day help meet Print Email Share.
While the aircraft has no moving parts, the craft will spin to provide stability, the same way that the barrel of a rifle spins a bullet to make it fly straight.
According to Colozza, about eight years ago a NASA team used ionised air propulsion to fly an aircraft that was attached to an external battery. The new aircraft needs air or at least a magnetic field in order to operate. Therefore it wouldn't work in space or fly between planets, although Roy says it could fly missions on other planets. Roy estimates that the first test flight could happen in as little as four months.
If successful, the physics of magnetohydrodynamics lend themselves to larger aircraft, making larger-scale versions of the WEAV possible. Whether the aircraft actually flies or not, it is already generating interest.
