Industry ELI5: Why is it not possible to create a perpetual motion
Perpetual motion is a misnomer, you can have perpetual motion. For instance, Newton''s First Law states "An object in uniform motion will remain in uniform motion". They go on to explain how net external forces can indeed change the motion of an object, and how. For instance, the earth has been moving at about 1000 miles per hour around the sun, for about 4 billion years. That''s not
Industry ELI5: Why a perpetual magnet engines do not work?
That''s not a perpetual motion machine. Once the weight hits the bottom, that''s it. You have to put energy back into the system to lift the weight up again and reset it. And the amount of energy you put in is always going to be more than you get back out. Magnet ''perpetual motion machines'' work exactly the same way, but you''re ''dropping'' the weight into a magnetic field instead of gravity.

A perpetual motion machine is a machine that can do work infinitely without an external energy source. But here, we most certainly do have an external energy source - the snow it picks up as it goes which apparently is converted to
Industry ELI5 Why can''t magnets create a true perpetual motion device.
Perpetual motion isn''t too hard to do - a pendulum in a vacuum is perpetual motion. Trying to use perpetual motion as a power source is something else entirely. Perpetual motion works because of conservation of energy; if the system doesn''t lose energy anywhere, then the kinetic energy is conserved and the motion won''t stop. (That''s why I said
Industry A brief history of Perpetual Motion machines
In 1905, the US Patent Office changed its rules for patenting a device that claims to draw useful energy from the ambient environment. For all other inventions, it suffices to submit to the office a detailed description of the device or process; for perpetual motion machines, a working model must be submitted. In practice, people who claim to

Industry Why aren''t planets considered perpetual motion machines?
So, perpetual machines on Earth require an infinite amount of energy put into a system to overcome the resistive forces present. Planets in space, however, only require a finite amount of energy to overcome their inertial resting state. Once in motion, they do not require any more energy in the absence of external forces.

There is a scientific consensus that perpetual motion in an isolated system violates either the first law of thermodynamics, the second law of thermodynamics, or both.The first law of thermodynamics is a version of the law of conservation of energy.The second law can be phrased in several different ways, the most intuitive of which is that heat flows spontaneously from

There would remain some very small residual motion of the pendulum due to the air molecules striking it at random (Brownian motion), but that does not count in the "game" of perpetual motion. In the condition of residual motion, the pendulum is just another (big) molecule sharing equally in the average kinetic energy of all the individual air molecules. In other words,

Pre-19th century. There are some unsourced claims that a perpetual motion machine called the "magic wheel" (a wheel spinning on its axle powered by lodestones) appeared in 8th-century Bavaria.This historical claim appears to be unsubstantiated though often repeated. Early designs of perpetual motion machines were done by Indian mathematician–astronomer Bhaskara II,

Industry Is perpetual motion possible in a vacuum (i.e. space)?
With perpetual motion devices usually the problem is energy conversion efficiency, it will be <100% no matter where you are. Also if you want something to react with a spinning wheel, the wheel will also react - by slowing down. You can''t take out more energy of a system that you put inside. And a spring has a lot of internal friction. In space

6 Frequently Asked Questions about “There is a perpetual motion device that does not require batteries”
Why can't we make a perpetual motion machine?
So let's breakdown perpetual motion machines and why we'll never be able to make one. The first law of thermodynamics is the law of conservation of energy. It states that energy is always conserved. It means that energy can be neither created nor destroyed. Instead, it simply changes from one form to another.
Does a perpetual motion machine need energy?
However, these perpetual systems never require any such energy source to operate. A machine that can work infinitely without an external energy source is known as the perpetual motion machine. Any motion that can be sustained without the need for any external sources of energy is referred to as perpetual motion.
Does a perpetual motion machine violate the law of Conservation of energy?
It thus violates the law of conservation of energy. A perpetual motion machine of the second kind is a machine that spontaneously converts thermal energy into mechanical work. When the thermal energy is equivalent to the work done, this does not violate the law of conservation of energy.
What is a perpetual motion machine?
A perpetual motion machine of the second kind is a machine that spontaneously converts thermal energy into mechanical work. When the thermal energy is equivalent to the work done, this does not violate the law of conservation of energy. However, it does violate the more subtle second law of thermodynamics in a cyclic process (see also entropy).
What is perpetual motion in physics?
Any motion that can be sustained without the need for any external sources of energy is referred to as perpetual motion. Note: A machine that operates on perpetual motion is a hypothetical machine. According to the laws of Physics, these machines are impossible to exist.
Why are perpetual motion machines still a fantasy?
But there is a reason why perpetual motion machines remain in the realm of fantasy; it's the Laws of Thermodynamics. Some inventions may appear to run by perpetual motion, but they usually rely on a hidden source of external energy. Both the First and Second Laws of Thermodynamics keep the perpetual motion car in the garage.
