It is observed that when we play with a flying disc, very less power is needed to make the disc float in air for given period of time. If the aeroplane are designed to use the same principle I think we can free this planet from green house effect.

A flying saucer has some very basic design flaws.
1. It needs to spin to be airborne
2. If not spinning it needs substantial downward force to keep in airborne
3. Steering is difficult. How often have to thrown the disc into the wind and made it go where you want it to?
Once airborne the airplane design does not require much power to keep it going. Therefore is more economical.

Extraterrestrials and UFOs are most definitely real, and I can prove it. Thanks to revelations made by the researcher John Bentley in his blog, we now know that a secret, highly-trained team has been studying the distant planet Frondar for some time. You won't have seen this on TV or in the press. It is currently only available to a small group of individuals with access to Bentley's blog. And he wants to keep this a secret, probably for military reasons. I, however, feel that the human race has a right to know what is going on. This is a revolutionary discovery and will affect us all. And only a few weeks ago, the team made contact with the highly intelligent Frondarian race. Many fascinating discoveries have been made about this race; for instance, they are half plant, half human, and have a remarkable ability to communicate with other species. Initial conversations with the Frondarians have shown that they are responsible for many of the UFO sightings that have been documented in the press over the last 50 years or so. They also state that if necessary, they will intervene further to save the planet Earth. As I said, I want to spread this information throughout the world. And for this reason I am pasting the link to Bentley's blog below. Please take a look, and then tell as many people as possible. We all need to do our bit to spread the word.

The design of a frisby, is a "wing". Exactly the same aerodymanic principles apply. Have you ever thought about how much it would cost for fuel to drive the same distance as an airplane flys. The cost is much less. To fly from California-Tenessee righ now is around $350.00, round trip. If you were to drive that distance it would cost you a lot more money for the fuel you would burn one way, not to mention comming back.
The real problem in the green house effect getting so bad is Automobiles. Everyone in America and India and China and Japan has cars and drice them everyday. In the U.S. we love our big SUV's which are a huge huge contributor to green house gasses. I see one person commuting in their large Escalade all the time. Most SUV's get around 20 MPG, why not get a car and increase your fuel milage to the 30's.
Half the weight of a Boeing 747 is the weight of its cargo (humans).......only a small fraction of the weight of an automobile is the weight of it cargo (usually only one person).
Sorry to go all green peace on you. But there are the facts.

How did you assume that very less power is required? The energy required to launch is considerable, the G-forces would be impressive at the time of launch and how will be the control of the spinning object?
Aeroplanes and design are always as practical as possible. It is not a vengeance mission to destroy the planet.

There were several experimentals built in the 50's exploring the flight characteristics of round planforms, but nothing successful. As one respondant has stated, you wouldn't want to spin the way a frisbee does, and that spinning is crucial to their success as a flying disc. Without the spin, it requires a substantial amount of power to maintain stability, which more than eliminates the gains you are thinking.
Would be cool, though.

Well.. maybe some day.. but remember the flying disc has an external powersource (you). It takes a fair amount of energy to get the disc flying. If it did not require an external power source perhaps your idea would be feasable.

way more energy would be required to move the disc as you are not ussing the laws of aerodynamics to help you such as lift and drag the energy that would be expended from the start would be less if you could just "chuck" people from point a to point b but for sustained flight planes are 10x more effeciant than your disc theory the key is sustained flight

Can you survive spinning that fast?
And do note that frisbees do come back to the ground
and paper airplanes fly too

How do you propose we give that design propulsion? Or control? Those are your major reasons why. Flying wing designs are more efficient, however, that is a relatively new design and we need to learn more about it.

Nope...
Flying disc's ( Frisbees ) SPIN to maintain stability...
Do you want to be in a spinning aircraft ??
