Dear Sir, I am Abhijit Patil, 33 serving as an Assistant with LIC of India. I have a Physics theory and based on this theory I believe, I have invention, a basic device like wheel, which can revolutionize entire transport industry on planet earth. This invention is about keeping things stationary in air by a mechanism so that these things do not fall on earth. This means, using aerodynamics and propellants, we can build vehicles to go from one place to another faster and cheaper which ordinary man can afford. For the sake of simplicity, I am talking about almost every bicycle, motorcycle, car, taxi, bus etc. on roads of planet earth up in the air. Time for a computation, methinks. I have a car 1 kg in mass I want to keep up in the air 4.905 m above my head (the strange value will be explained in a moment). Now, with no power source it simply falls to the ground with an acceleration of 9.81 m/s/s in 1 second once let go, doing 4.905 * 9.81 = 48.11805 J of mechanical work, some of it to the car itself, some of it to the ground. If one is lucky it will simply make an interesting noise. In order to keep that thing in the air without something so mundane as a pillar, post, or hook, one has to figure out how to have something else take the fall. In this case, the something else is air molecules. That 48.11805 J of mechanical work is also expressible as momentum; the car is moving at 9.81 m/s after that first second. That's a momentum of 9.81 kg m/s. If we want to keep it up some air has to be moved at a sufficient velocity to match that momentum, in the opposite direction -- every second. Fans are commonly expressed as cubic feet per minute. This annoying (to SI) measurement can be converted to grams per second. Regrettably, the velocity is rarely given but one can compute it based on the usable area of the fan. 1 cubic meter of air is about 40 moles of air, or about 1.16 kg. If we move 1 kg of air per second downward at a velocity of 9.81 m/s, we have accomplished our task -- but at what cost? The cost of accelerating that air, mostly -- and that energy is 48.11805 W (1/2 * 1 kg/s * (9.81)^2 m/s). If we move 10 kg of air per second downward at .981 m/s using a wider fan, we can reduce that power expenditure to 4.811805 W. It behooves us to make the car as wide and as flat as we can, although other effects might get in the way, such as wind gusts from Earth's weather patterns. I weigh about 100 kg. (Actually, I weigh more than that.) It is far from clear that I can generate more than a few hundred watts of power, although it's quite possible for a good bicyclist to fly, as proven by the Gossamer Albatross some years back. But he was far skinnier than I. (Ideally, the air would be taken from the sides of the car, not the top, and directed downward through 90 angle tubes. The reasons for this should be fairly obvious; the moving air will exert a downward pressure on the car. How much, I'm not sure.) A good D cell can generate 16500 mAh, or 59.4 kJ. After that one either has to recharge it or replace it. I'll be lucky if that can keep me up for a fifth of a second -- and its weight is 134 grams. A cunningly-employed kg of gasoline would generate 45 MJ and might keep me up there for a day, given a big enough and light enough fan that can move 1 metric tonne of air a second at 1 m/s or so.

Please concentrate on FIG.2, which is at heart of this invention and most simple, at the same time most difficult part to understand in this invention. Ref: http://chronicle.com/free/v49/i21/21b02001.htm The Seven Warning Signs of Bogus Science By ROBERT L. PARK The National Aeronautics and Space Administration is investing close to a million dollars in an obscure Russian scientist's antigravity machine, although it has failed every test and would violate the most fundamental laws of nature. The Patent and Trademark Office recently issued Patent 6,362,718 for a physically impossible motionless electromagnetic generator, which is supposed to snatch free energy from a vacuum. And major power companies have sunk tens of millions of dollars into a scheme to produce energy by putting hydrogen atoms into a state below their ground state, a feat equivalent to mounting an expedition to explore the region south of the South Pole. There is, alas, no scientific claim so preposterous that a scientist cannot be found to vouch for it. And many such claims end up in a court of law after they have cost some gullible person or corporation a lot of money. How are juries to evaluate them? Before 1993, court cases that hinged on the validity of scientific claims were usually decided simply by which expert witness the jury found more credible. Expert testimony often consisted of tortured theoretical speculation with little or no supporting evidence. Jurors were bamboozled by technical gibberish they could not hope to follow, delivered by experts whose credentials they could not evaluate. In 1993, however, with the Supreme Court's landmark decision in Daubert v. Merrell Dow Pharmaceuticals, Inc. the situation began to change. The case involved Bendectin, the only morning-sickness medication ever approved by the Food and Drug Administration. It had been used by millions of women, and more than 30 published studies had found no evidence that it caused birth defects. Yet eight so-called experts were willing to testify, in exchange for a fee from the Daubert family, that Bendectin might indeed cause birth defects. In ruling that such testimony was not credible because of lack of supporting evidence, the court instructed federal judges to serve as "gatekeepers," screening juries from testimony based on scientific nonsense. Recognizing that judges are not scientists, the court invited judges to experiment with ways to fulfill their gatekeeper responsibility. Justice Stephen G. Breyer encouraged trial judges to appoint independent experts to help them. He noted that courts can turn to scientific organizations, like the National Academy of Sciences and the American Association for the Advancement of Science, to identify neutral experts who could preview questionable scientific testimony and advise a judge on whether a jury should be exposed to it. Judges are still concerned about meeting their responsibilities under the Daubert decision, and a group of them asked me how to recognize questionable scientific claims. What are the warning signs? I have identified seven indicators that a scientific claim lies well outside the bounds of rational scientific discourse. Of course, they are only warning signs -- even a claim with several of the signs could be legitimate. 1. The discoverer pitches the claim directly to the media. The integrity of science rests on the willingness of scientists to expose new ideas and findings to the scrutiny of other scientists. Thus, scientists expect their colleagues to reveal new findings to them initially. An attempt to bypass peer review by taking a new result directly to the media, and thence to the public, suggests that the work is unlikely to stand up to close examination by other scientists. One notorious example is the claim made in 1989 by two chemists from the University of Utah, B. Stanley Pons and Martin Fleischmann, that they had discovered cold fusion -- a way to produce nuclear fusion without expensive equipment. Scientists did not learn of the claim until they read reports of a news conference. Moreover, the announcement dealt largely with the economic potential of the discovery and was devoid of the sort of details that might have enabled other scientists to judge the strength of the claim or to repeat the experiment. (Ian Wilmut's announcement that he had successfully cloned a sheep was just as public as Pons and Fleischmann's claim, but in the case of cloning, abundant scientific details allowed scientists to judge the work's validity.) Some scientific claims avoid even the scrutiny of reporters by appearing in paid commercial advertisements. A health-food company marketed a dietary supplement called Vitamin O in full-page newspaper ads. Vitamin O turned out to be ordinary sal****er. 2. The discoverer says that a powerful establishment is trying to suppress his or her work. The idea is that the establishment will presumably stop at nothing to suppress discoveries that might shift the balance of wealth and power in society. Often, the discoverer describes mainstream science as part of a larger conspiracy that includes industry and government. Claims that the oil companies are frustrating the invention of an automobile that runs on water, for instance, are a sure sign that the idea of such a car is baloney. In the case of cold fusion, Pons and Fleischmann blamed their cold reception on physicists who were protecting their own research in hot fusion. 3. The scientific effect involved is always at the very limit of detection. Alas, there is never a clear photograph of a flying saucer, or the Loch Ness monster. All scientific measurements must contend with some level of background noise or statistical fluctuation. But if the signal-to-noise ratio cannot be improved, even in principle, the effect is probably not real and the work is not science. Thousands of published papers in para-psychology, for example, claim to report verified instances of telepathy, psychokinesis, or precognition. But those effects show up only in tortured analyses of statistics. The researchers can find no way to boost the signal, which suggests that it isn't really there. 4. Evidence for a discovery is anecdotal. If modern science has learned anything in the past century, it is to distrust anecdotal evidence. Because anecdotes have a very strong emotional impact, they serve to keep superstitious beliefs alive in an age of science. The most important discovery of modern medicine is not vaccines or antibiotics, it is the randomized double-blind test, by means of which we know what works and what doesn't. Contrary to the saying, "data" is not the plural of "anecdote." 5. The discoverer says a belief is credible because it has endured for centuries. There is a persistent myth that hundreds or even thousands of years ago, long before anyone knew that blood circulates throughout the body, or that germs cause disease, our ancestors possessed miraculous remedies that modern science cannot understand. Much of what is termed "alternative medicine" is part of that myth. Ancient folk wisdom, rediscovered or repackaged, is unlikely to match the output of modern scientific laboratories. 6. The discoverer has worked in isolation. The image of a lone genius who struggles in secrecy in an attic laboratory and ends up making a revolutionary breakthrough is a staple of Hollywood's science-fiction films, but it is hard to find examples in real life. Scientific breakthroughs nowadays are almost always syntheses of the work of many scientists. 7. The discoverer must propose new laws of nature to explain an observation. A new law of nature, invoked to explain some extraordinary result, must not conflict with what is already known. If we must change existing laws of nature or propose new laws to account for an observation, it is almost certainly wrong. I began this list of warning signs to help federal judges detect scientific nonsense. But as I finished the list, I realized that in our increasingly technological society, spotting voodoo science is a skill that every citizen should develop. Robert L. Park is a professor of physics at the University of Maryland at College Park and the director of public information for the American Physical Society. He is the author of Voodoo Science: The Road From Foolishness to Fraud (Oxford University Press, 2002). |

Please visit my homepage http://www.geocities.com/action_device and please verify yourself or through your Engineers whether this invention works or not. I stand corrected. I thought you were proposing a real underpowered flying machine. Now I see the most likely Bayesian prior is that you are a fraud -- this is a mark of respect for the Indian technical education system, since I am refusing to believe that as a trained engineer _you_ really believe this. You or your co-conspirators however have written a very professional looking patent application: I have no doubt if your particular species of fraud has not been perpetrated with the blessings of our countries' respect patent offices that it will be now. Patent examination is another one of the many methods available of beating the integrity out of a man in response to economic stimulus: a perfect partner with the law. 87.5% of all people can be formed into ethical cretins with the slow but inexporable application of economic force. You fit right into society, and should go far. |

P.S. I seem to have found a small typo in your patent application:
(Abhi) wrote in message om... This invention is about keeping things stationary in air by a mechanism so that these things do not fall on earth. This means, using aerodynamics and propellants, we can build vehicles to go from one place to another ... Whereas later you write: In other words this device will not allow the body or the device itself to fall on planet even in vacuum without using aerodynamics or propellant. I guess you meant the "with" version to be prior art? |
