At the current rate of decrease, the Earth's rotation relative to the Sun would stop in 5.4 billion years. Very careful measurements can detect such changes, and they are predictable based on the tidal interaction with the sun and the moon. The rotation of the Earth does not change perceptibly in any person's lifetime. There are many systems in nature that for practical purposes are perpetual. It also gives a basis for considering another lesser goal of perpetual motion, which is to produce a device that will run forever with no further external inputs. It clearly states that the goal of getting more energy output than the energy input is impossible. This law is, therefore, a good basis from which to analyze perpetual motion machines. This law is based, however, not on this negative result, but on all the experiments performed to date in which energy is carefully accounted for. The nonexistence of perpetual motion machines, despite centuries of effort to design them, has been used to support the law of conservation of energy. Patent Office has a policy to not examine applications covering perpetual motion machines unless the applicant furnishes a working model. To prove that a particular design of a perpetual motion machine will not work can be very time consuming, and the predictable negative result has never been worth the effort. ![]() Wilkins proposed using the magnetic material lodestone, not a superconducting magnet. Was proposed by John Wilkins in the 1670s. The first perpetual motion device using magnetic forces The details can be quite complicated, but when any design is correctly analyzed it is always found that the energy required to turn the magnetic or electric field on and off, or to move the field from place, to place exceeds the work obtained by the falling weight. The magnet can continually lift and drop the weight. Then, when the magnetic field is turned off or taken away, the falling weight can be harnessed to do useful work. For instance, a weight can be lifted by a magnetic field, perhaps produced by a superconducting magnet, with no power loss. Would-be inventors frequently employ magnetic or electrostatic interactions because these forces are less understood (by them). Friction will always cause such a water wheel to "grind" to a halt even in the absence of doing useful work. The only problem with this device is that it took more energy to pump the water than the entire energy output of the water wheel. The remaining portion of the output could then be used to operate a flour mill. He designed a pump to drive some of the output from a water wheel to recirculate water upstream, which would then run over the wheel again. Robert Fludd in 1618 was one of the first to discover it is impossible to get something for nothing. ![]() They can easily be scaled up so once you have it working you can make a larger one depending on how much electricity you need to generate.The idea of perpetual motion, which has been around for centuries, is to make a device that will produce more work output than the energy input-in short, to get something for nothing. They also outline all the equipment and parts that you need. There are some really poor designs that people are trying to sell for hundreds of dollars.ĭon't waste your money though, a decent set of magnetic generator plans will cost you a lot less. It's a simple idea but to get it working you need a good set of plans. It's easy to understand how the continuous motion caused by the ability of magnets to repel each other could be used to generate electricity.Īny kind of perpetual motion generator is powered by permanent magnets. Most folks are familiar with magnets and can easily grasp how the idea works. The magnetic generator is based on perpetual motion which is created through the power of magnetism. They are missing the point though because at the end of the day you are still generating free electricity! A lot of folks will say that it's not a true perpetual motion generator, and they are correct. The thing is though, the magnetic generator which has become so popular in recent years actually requires a small amount of electricity to keep the perpetual motion going. You would be a fool to argue with the law of relativity.
