Actually, the laws of thermodynamics say energy can neither be created nor destroyed.  This does not mean that We cannot access the infinite energy in the aether...  In fact, drawing energy from the aether is what free energy devices do.

But they're not defying the laws of thermodynamics.

The einsteinian bunk, foisted upon Us to hide the energy in the aether, say We cannot have free energy, but LaViolette's work, subquantum kinetics (SQK) predicts the energy in the aether - and needs nothing ad hoc, like "dark matter," "dark energy," and "bending of spacetime," which were tacked onto the einsteinian garbage to make it work.

SQK is euclidean.

So...  Yes, We can have free energy.
