magnet gravity

Couldn't, with well position magnets, create an orbit around a central magnet? Almost like perpetual motion? I've been playing around with magnets lately, and I've gotten magnets to do 2 full revolutions around other magnets before coliding. Is it possible?

My Theory for How Gravity Works

So I've never really found out how gravity actually works, why it happens. But a few days ago I had a epiphany. I don't know if I spelled that right. So everything is at least a little bit magnetic, even stuff like wood, no matter how little. So all of this stuff would be attracted to all the other stuff electromagnetically, right? Even a little bit? So when you get huge amounts of this stuff (I'm thinking planets here) there is enough electromagnetic attraction to pull it together, and voila! We have gravity! Plus when you have planets, there's tons of stuff like iron and other metals and metaloids, that could be very strong, magnetically. So if I'm wrong (which I probably am), can someone explain how gravity actually works to me? I'm constantly thinking about stuff like this, I get theories like this every once in a while, many of them right. But not this complicated, more stuff like figuring out how air pressure and vacuums work, but basic principle stuff.

Gravity Lamp, the LED lamp powered by gravity

A Virginia Tech student designed an LED lamp that is powered by gravity. It is called the Gravia, and it took second place at the Greener Gadgets competition in NYC. Gravity as a renewable energy source? Amazing!From http://pesn.com/2008/02/19/9500471_Gravity_Lamp/Concept illustrations of Gravia depict an acrylic column a little over four feet high. The entire column glows when activated. The electricity is generated by the slow fall of a mass that spins a rotor. The resulting energy powers 10 high-output LEDs that fire into the acrylic lens, creating a diffuse light. The operation is silent and the housing is elegant and cord free – completely independent of electrical infrastructure.The light output will be 600-800 lumens – roughly equal to a 40 watt incandescent bulb. Each drop of the gravity mechanism runs the light over a period of four hours.To "turn on" the lamp, the user moves weights from the bottom to the top of the lamp. An hour-glass like mechanism is turned over and the weights are placed in the mass sled near the top of the lamp. The sled begins its gently glide back down and, within a few seconds, the LEDs come on and light the lamp, Moulton said. “It’s more complicated than flipping a switch but can be an acceptable, even enjoyable routine, like winding a beautiful clock or making good coffee,” he said.Moulton estimates that Gravia’s mechanisms will last more than 200 years, if used eight hours a day, 365 days a year.The winner of the Greener Gadgets competition was the Enerjar.

Alas, it was not to be. Four days later and most of my sparkles are at the bottom of the jar. Question: Does anybody have an idea or suggestion or anything to keep the sparkles where they are?

A Challenge: DIY gravity lamp

I have decided to power the lighting in my house with gravity alone starting next year. The idea started here: Greener Gadgets: Gravity LampI have some ideas about how to make it possible using some existing instructables and I though I would share this to get people thinking about new ways to use gravity as a power source. Think about it, gravity is clean, constant, eternal and EVERYWHERE. I think that this instructable has some of the essential components: Cordless Drill Crank Charge BatteriesIt gives a basic example of kinetic energy being converted into electricity, but for this application the kinetic energy will be supplied by gravity instead of the hand crank. The real fun with this project, I think, is the different ways that the kinetic energy of the weight can be harnessed. The screw used by the Gravity Lamp is just one method. A weight on a rope that is wrapped around a spool or crank is another option or even something based on the mechanism of a grandfather clock. One could even imagine a single massive weight that the whole family would hoist, with the help of pulleys, every evening to power their home lighting. Who knows.....It's time to start a gravity revolution.

Anti Gravity

SCIENTISTS in Finland are about to reveal details of the world's first anti-gravity device. Measuring about 12in across, the device is said to reduce significantly the weight of anything suspended over it.The claim - which has been rigorously examined by scientists, and is due to appear in a physics journal next month - could spark a technological revolution. By combating gravity, the most ubiquitous force in the universe, everything from transport to power generation could be transformed.The Sunday Telegraph has learned that Nasa, the American space agency, is taking the claims seriously, and is funding research into how the anti-gravity effect could be turned into a means of flight.The researchers at the Tampere University of Technology in Finland, who discovered the effect, say it could form the heart of a new power source, in which it is used to drive fluids past electricity-generating turbines.Other uses seem limited only by the imagination:Lifts in buildings could be replaced by devices built into the ground. People wanting to go up would simply activate the anti-gravity device - making themselves weightless - and with a gentle push ascend to the floor they want.Space-travel would become routine, as all the expense and danger of rocket technology is geared towards combatting the Earth's gravitation pull.By using the devices to raise fluids against gravity, and then conventional gravity to pull them back to earth against electricity-generating turbines, the devices could also revolutionise power generation.According to Dr Eugene Podkletnov, who led the research, the discovery was accidental. It emerged during routine work on so-called "superconductivity", the ability of some materials to lose their electrical resistance at very low temperatures. The team was carrying out tests on a rapidly spinning disc of superconducting ceramic suspended in the magnetic field of three electric coils, all enclosed in a low-temperature vessel called a cryostat."One of my friends came in and he was smoking his pipe," Dr Podkletnov said. "He put some smoke over the cryostat and we saw that the smoke was going to the ceiling all the time. It was amazing - we couldn't explain it."Tests showed a small drop in the weight of objects placed over the device, as if it were shielding the object from the effects of gravity - an effect deemed impossible by most scientists."We thought it might be a mistake," Dr Podkletnov said, "but we have taken every precaution". Yet the bizarre effects persisted. The team found that even the air pressure vertically above the device dropped slightly, with the effect detectable directly above the device on every floor of the laboratory.In recent years, many so-called "anti-gravity" devices have been put forward by both amateur and professional scientists, and all have been scorned by the establishment. What makes this latest claim different is that it has survived intense scrutiny by sceptical, independent experts, and has been accepted for publication by the Journal of Physics-D: Applied Physics, published by Britain's Institute of Physics.Even so, most scientists will not feel comfortable with the idea of anti-gravity until other teams repeat the experiments. Some scientists suspect the anti-gravity effect is a long-sought side-effect of Einstein's general theory of relativity, by which spinning objects can distort gravity. Until now it was thought the effect would be far too small to measure in the laboratory.However, Dr Ning Li, a senior research scientist at the University of Alabama, said that the atoms inside superconductors may magnify the effect enormously. Her research is funded by Nasa's Marshall Space Flight Centre at Huntsville, Alabama, and Whitt Brantley, the chief of Advanced Concepts Office there, said: "We're taking a look at it, because if we don't, we'll never know."The Finnish team is already expanding its programme, to see if it can amplify the anti-gravity effect. In its latest experiments, the team has measured a two per cent drop in the weight of objects suspended over the device - and double that if one device is suspended over another. If the team can increase the effect substantially, the commercial implications are enormous. Okay. lets throw down our ideas and see if we can figure something out... or not

What is the cause of gravity?

A friend of mine MUSAB said that  two bodies attract each other because the electrons and protons of both their atoms attract each other, however, I don't think this is the case, I have heard from some where else that it is due to distortion in space time created by a mass and geodesics are formed and they bend towards the center of the mass due to which every other body which comes in its gravitational field tends to move towards its center and all that stuff I have studied in detail. So who is right? If he is wrong, then please also specify where is he wrong, I think that individual atoms can not attract each other because of charge because an atom, as a whole, is a neutral particle. Thanks in advance.

I've been working on this (hobby status) on and off over the last fifteen years or so.... a mechanism that immediately begins to rotate in either direction with an imbalancing displacement of as little as one degree. With repeated periodic displacements of as little as five to seven degrees its rate of rotation rapidly approaches about a 100 to a 150 rotations per minute over the course of just eight to ten repetitions, all while overcoming only negligible frictional resistance from the main axel (equipped with bearings). It may have some applications for extracting rotational motion more efficiently from wind and wave and maybe a couple of other things too.... or it may just be a work of art.

Possibility of "gravity chamber" becoming a reality

I used to watch the show  "Dragon Ball Z" when I was younger, on some of the episodes there was a gravity chamber which would increase the gravity in the room. It would go up to 450G (1G= 1 times the Earth's gravity) I know this is completely impossible but could a device like this even exist and if it did would make it to 2G's? Before you respond I know this is just a show and not reality. If this did work this would help athletes train and astronauts (if and when the moon is colonized)

Anti-gravity Machine concept

This is a concept I came up with for an idea of an anti-gravity machine.  Let me just state for the record... I do not think this will actually work.  However, while I am quite certain this idea should not work... based upon my limited knowledge of science... it would seem like it could work.  Unfortunately I know I am never going to spend the thousands if not millions of dollars to build this concept to find out. The basic premise of the idea is the use of angular momentum to overcome the force of gravity.  Imagine if you will, a gyroscope spinning at such a high velocity that its outward force overcomes the downward force of gravity.  Naturally, one of the big obstacles is generating the speeds necessary to create the velocity such that angular momentum is greater than downward force. What I essentially propose is a spinning ring that is propelled in the same way as a maglev train.  Using Electromagnetic propulsion or EMP to accelerate a ring in a vacuum by the utilization of a flowing electrical current and magnetic fields may in theory generate the speeds necessary for the force to overcome gravity.  Unfortunately, the power to run such a vehicle and the weight to power ratio are significant obstacles. Two of these rings above one another I theorize can create tremendous propulsion if the angles of the rings were changed.  Using hydrolics to change the angle of alignment of these two rings may create incredible forward momentum.  Once more, such a vehicle would not be limited to operation within Earth's atmosphere unlike jet or other propulsion mechanisms.  In fact, it should operate at peak efficiency in a zero gravitational environment. This is all theory... and I'd love to know if it is indeed as crazy as it sounds.

What is the definition of "matter" according to the string theory? Answered

Hello!  I have recently studied about the string theory. Now what I have understood about it so far is that very small particles like the one's that make up neutrons and protons are actually made up of "strings" that vibrate in 10 dimensions at particular frequencies which determine the nature of the particles that they form. I also came to know that "strings" themselves are weird distortions of space-time.   Now I don't know if all that information is correct or not. So my question is that according to it, it would mean that matter itself is a distortion of space-time, is this true?

OK I had this idea. I was online and thought up this idea for an anti gravity machine. This is it: use extremely static negatively charged materials for anti gravity. It could work the same way lightning clouds do. The base of the cloud is negatively charged and the ground become positively charged. Now if the material of the anti gravity "thing" is charged with static electricity, wouldn't it repel the ground? Now I am by far no expert in any of this...I just thought it up.
