Question about perpetual machines...

[linux kid]

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.
