    Machines
In summary, the conversation revolved around the topic of perpetual motion machines and whether or not they should be allowed to be discussed on PF. One person questioned the limitation on discussing such machines, while another explained that it goes against the forum's rules on speculative posts. The consensus was that perpetual motion machines do not exist and therefore should not be discussed on the forum.

If there was a machine that claimed to have all the characteristics of such a machine and relied on gravity, can it be called a perpetual machine?

What is this some oil propaganda? I don't see why we can't discuss this topic. Why must we further limit our freedom, IMO this is pure nonsensical.

Perpetual motion machines don't exist and any discussion of one exceeds our limits on speculative posts, which is why they are not discussed here.

If you had read the post ranger provided, you would understand why.
 

1. What is a perpetual machine?

A perpetual machine is a hypothetical device that can continue to function or operate indefinitely without any external energy source. It is often described as a machine that can produce more energy than it consumes, thus creating a never-ending cycle of energy.

2. Is it possible to create a perpetual machine?

According to the laws of thermodynamics, it is impossible to create a perpetual machine. The first law states that energy cannot be created or destroyed, only transferred or converted. This means that a perpetual machine would violate this law by creating energy out of nothing.

3. Why are perpetual machines considered impossible?

Aside from violating the first law of thermodynamics, perpetual machines are also impossible due to factors such as friction, air resistance, and mechanical wear and tear. These factors would eventually cause the machine to slow down and stop, unable to continue functioning indefinitely.

4. Have any perpetual machines been successfully created?

No, there have been no successful demonstrations of a perpetual machine. Many attempts have been made throughout history, but all have been proven to be either hoaxes or misunderstandings of how the machine actually works.

5. Are there any real-world applications for perpetual machines?

While perpetual machines are not possible, the concept has sparked scientific advancements in the field of renewable energy. The pursuit of creating a perpetual machine has led to the development of more efficient and sustainable energy sources, such as solar panels and wind turbines.
