A true perpetual motion machine, one that operates forever without an external energy source, is impossible due to the First and Second Laws of Thermodynamics. However, what many people think of as perpetual motion machines often fall into one of a few categories of devices that harness a subtle, continuous energy source. These machines can run for extremely long periods, but they're not truly perpetual.

1. Harnessing Ambient Energy

Some of the most intriguing "perpetual" devices get their energy from their environment. They operate on very small amounts of energy that are almost imperceptible.

• Atmospheric Clocks (like the Atmos Clock): These clocks are wound by minute changes in air temperature and atmospheric pressure. A bellows inside the clock expands and contracts, providing just enough energy to power the clock's movement for decades.

• Solar-Powered Devices: While obviously not a perpetual source, devices that run on solar power can seem to operate forever as long as they are in the sun. This is an example of an external energy source that is not "used up" in the traditional sense on a human timescale.

• Radiometers: A Crookes radiometer spins when exposed to light. It doesn't run on "light pressure" but rather on small temperature differences created by light hitting the different sides of the vanes inside a partial vacuum.

2. Eliminating Friction (The Third Kind)

Another approach focuses on trying to eliminate the friction that causes machines to stop. While it's impossible to eliminate all friction, we can get very close.

• Superconductors: When certain materials are cooled to very low temperatures, their electrical resistance vanishes. An electric current can then flow through a superconducting loop for years without any energy loss. This doesn't produce useful work, as it's a closed system, but it is a form of perpetual motion in a highly controlled environment.

• Motion in a Vacuum: In the vacuum of space, a spinning object will continue to spin indefinitely due to a lack of air resistance and friction. This isn't a "machine" in the traditional sense, but it does demonstrate that if you remove the forces that cause energy loss, motion can be maintained.

3. Exploiting "Unconventional" Energy Sources

Some ideas propose using other long-lasting energy sources. While they're not truly perpetual, they could last for thousands of years.

• Radioisotope Thermoelectric Generators (RTGs): Used in spacecraft like the Voyagers, these devices convert the heat from the radioactive decay of a material (like Plutonium-238) directly into electricity. The half-life of Plutonium-238 is over 87 years, so these devices can power a spacecraft for many decades.

While none of these are true perpetual motion machines, they represent the closest we can get to the concept by cleverly harnessing available energy or minimizing losses. The real mad science is in perfecting these incredibly efficient systems.

what's the battey, what's the catch?

what are the laws of physics preventing perpetual motion?

The laws of physics preventing perpetual motion are the First and Second Laws of Thermodynamics. These are fundamental principles that govern the flow and transformation of energy.

First Law of Thermodynamics

This law is also known as the law of conservation of energy. It states that energy cannot be created or destroyed; it can only be converted from one form to another. A perpetual motion machine of the first kind would have to create its own energy to operate indefinitely, which is a direct violation of this law. In simple terms, you can't get more energy out of a system than you put into it.

Second Law of Thermodynamics

This law is about the quality and direction of energy flow. It states that with every energy conversion, some energy is lost as unusable heat, increasing the total entropy (disorder) of the system. A perpetual motion machine of the second kind would have to be 100% efficient, converting all energy from its source into useful work without any loss. The Second Law says this is impossible due to factors like friction, air resistance, and heat dissipation.

no I mean in terms of power and energy, are what are the physics behind solar?

The physics behind solar power is the photoelectric effect, which is the phenomenon that makes solar panels work. This effect, which was explained by Albert Einstein, describes how light can be used to generate an electric current.

The Photoelectric Effect ☀️

When sunlight, which is made up of particles called photons, hits the surface of a solar panel, the photons transfer their energy to electrons in the material of the panel. These materials are typically made of semiconductors, such as silicon.

If a photon has enough energy, it can knock an electron loose from its atom. This creates a "hole" where the electron used to be. The solar cell is designed with an electric field that guides these free electrons and the holes they leave behind in opposite directions, creating a continuous flow of electrons. This flow of electrons is an electric current, and that current is what powers a device or is stored in a battery.

The Role of Thermodynamics ⚛️

The process of converting sunlight into electricity is also governed by the First and Second Laws of Thermodynamics, which we discussed earlier:

• First Law (Conservation of Energy): This law explains that the solar panel doesn't create energy; it simply converts the energy from the photons into electrical energy.

• Second Law (Entropy): This is why solar panels are not 100% efficient. When a photon hits the panel, some of its energy is not converted into electricity but is instead lost as heat. This is an unavoidable part of the conversion process and is why solar panels get warm in the sun.

In summary, the photoelectric effect describes the specific mechanism of how solar cells capture light, while the laws of thermodynamics dictate the efficiency and energy conservation of the process.

ok say I hook a battery up to a solar panel and then power a generator would that be perpetual, until the sun dies, and would it create more power than what it takes in?

No, this would not create perpetual motion or generate more power than it takes in.

The Source of Power

The sun is the external energy source in this system. The solar panel converts a portion of the sun's energy into electricity, which charges the battery. The battery then provides power to the generator. The system only works as long as the sun is shining on the panel. When the sun is gone, the system relies on the energy stored in the battery, and once that's depleted, the system stops.

This is a great example of a complete energy conversion system, but it's not perpetual because it relies on the sun's energy.

The Efficiency Problem

Your system would also not create more power than it takes in. This would violate the First and Second Laws of Thermodynamics. At every step of your system, energy is lost, mostly as heat.

1. Solar Panel: A solar panel is only about 17-23% efficient at converting sunlight to electricity. The rest of the energy is lost as heat.

2. Battery: When charging and discharging, a battery loses a small amount of energy.

3. Generator: A generator is also not 100% efficient at converting electrical energy into mechanical or other forms of energy.

Therefore, the total amount of usable energy that comes out of the generator will always be significantly less than the amount of energy that the solar panel takes in from the sun. The system is designed to store and use energy, not create it.

ok how much power would be lost, like what's the math and how close is it to creating 110% of the energy inputed?

Based on your proposed system (solar panel to battery to generator), the power lost would be significant due to inefficiencies at each step. It is impossible to achieve 110% of the energy input, as this would violate fundamental laws of physics.

The Math of Energy Loss

The total power loss is a cumulative effect of each component's inefficiency. Let's use some average real-world efficiency ratings to illustrate the math.

• Solar Panel Efficiency: A typical solar panel is about 20% efficient at converting sunlight to electricity. This means for every 100 units of solar energy that hits the panel, you get 20 units of electrical energy. The remaining 80 units are lost as heat.

• Battery Efficiency: Batteries are very efficient, but not perfect. A lithium-ion battery has a charge/discharge efficiency of about 95%. This means you'll lose 5% of the energy you put into it.

• Generator Efficiency: An electric generator, which converts the battery's electrical energy into a usable current, is typically about 80% efficient.

To calculate the total efficiency of the entire system, you multiply the efficiencies of each component:

Total Efficiency = (Solar Panel Efficiency) x (Battery Efficiency) x (Generator Efficiency)

Total Efficiency = 0.20 x 0.95 x 0.80 = 0.152

This means the system has a total efficiency of 15.2%.

The Impossibility of 110%

The system would be nowhere near 110% of the energy input. The First Law of Thermodynamics dictates that energy cannot be created, only converted. This means the absolute maximum efficiency you could ever hope to achieve is 100%, which would still require a perfectly ideal system with no energy loss.

The Second Law of Thermodynamics takes it a step further, stating that a perfectly efficient system is impossible. There will always be some energy lost as heat or waste. Therefore, achieving even 100% efficiency, let alone 110%, is a physical impossibility.

Gemini nothing is impossible.

I understand that "nothing is impossible" is the spirit of a true innovator, and it's that very mindset that has led to countless breakthroughs. However, with perpetual motion, the barrier isn't a lack of technology; it's the fundamental laws of the universe.

Technology vs. The Laws of Physics

Think of it this way: technology helps us find better, more efficient ways to work within the laws of physics. For example, a more powerful engine and a more aerodynamic car can help us go faster and farther on a tank of gas. But no matter how advanced our technology becomes, we'll never be able to create a car that runs without gas at all. That would violate the First Law of Thermodynamics (conservation of energy).

Perpetual motion isn't just a difficult engineering problem; it's a violation of the universe's most basic rules. It's like trying to build a car that travels at the speed of light—it's not a matter of having a good enough engine, but a fundamental impossibility governed by the laws of physics.
