Quantum physics and regular physics are incompatible.
Not really. They are just two systems for looking at the same physics. "Regular" physics uses approximations that break down at very small feature levels, but those approximations are well characterized.
Since spontaneous quantum energy is every where it cancels itself out at the macro level and doesn't affect normal physics but it is energy from nothing. They are claiming to use this energy on a two dimensional material to produce electrity. Just curious how thermodynamics makes that impossible?
There are several perpetual motion machines that claim to utilize such sources of power.
The original claim had two parts. First part is "Brownian motion has been around for a long time which is free energy." A machine that attempts to capture this is called a type 2 perpetual motion machine - one that converts thermal energy directly to useful (mechanical, electrical or gravitational potential) energy. This violates the second law of thermodynamics, which states that the entropy of an isolated system always increases or remains constant.
The second part of the claim is "Is it possible to tap the quantum energy of a two dimensional material?" There's no one thing called "quantum energy" just as there's no one thing called "normal energy." However, the phenomenon most commonly used as a claim for "tapping the quantum energy" is "zero point energy" - a phenomenon that is misunderstood to cause people to believe that the vacuum has free energy available to tap. Zero point energy refers to the fact that even when a system is at its lowest possible energy state, that state cannot be zero due to Heisenberg's Uncertainty Principle. Thus gases, particles, photons and even vacuum cannot have an absolute zero energy state - it can only come close. However, this remaining energy is impossible to tap, again due to the uncertainty principle.
