not once in the last hundred years has the second law of thermodynamics been under threat - and never will be....
near-unity machines have always failed due to the strenuous requirements of measurement at the levels of gain reported for such systems - the uncertainties of measurement, let alone accounting accurately for ALL inputs renders the job pointless....
there is a simple test for over-unity machines of any nature..... if there is 'excess' energy from one machine, then feed the output into the next machine, and so on.... eventually you'd have a massive amount of cascading free energy which could easily be measured against inputs - but it's never been done - I wonder why?
