This reminds me of an occasion about ten years ago when a company using some kind of water pump* found they were getting more energy out than they were putting in. Rather an extraordinary claims.

Some scientists came out to investigate. Sure enough, the meters appeared to register efficiency of about 120%.

However, looking further, the scientists realised that these final readings were based on a series of readings that had rather broad tolerances, so they were meaningless.

So, no extraordinary evidence for this extraordinary claim.

But the ones who thought they had overturned thermodynamics made dismissive remarks about these arrogant scientists clinging to their beliefs. Yawn.

*I forget the exact details.
