Following the links at the end of the article leads me to
https://superinnovators.com/2024/06/new-method-makes-hydrogen-from-solar-power-and-cow-dung/
so they have reduced the energy to make hydrogen by 600%.
If they reduce it by 100% then it takes no energy at all. Beyond that it ‘s a free energy device so I’d better shut up about it.
The entire site reads like AI generated misinformation. The actual cow dung paper warns against using such bogus efficiency numbers.
While this non-circular approach has been used in the literature with some degree of utility for conceptual purposes, it should be used with caution, having also been referred to as a pseudo-energy efficiency to highlight the importance of accounting for the energy content of various reactants—for instance, in the pseudo-energy efficiency calculation, "efficiencies" in excess of 100% can be calculated.

Reminds me a lot of the lemon battery fallacy. Where countries with spare lemons (or whatever acidic fruit) think that they can produce limitless electricity from it, without realising that the energy comes from the zinc electrode which is consumed in the process, not the fruit.

Historic tourist attraction loses $170K worth of donations after going cashless
Visitors to the Roman Baths in Bath have been stopped from throwing money into the historic attraction and are instead asked to make a contactless payment.
What a God forsaken stupid idea ... there is no way I'm going to go through the trouble (and the risk) of making a wireless payment (which will most probably also have a process fee) instead of just throwing a few coins out of impulse.
