The music on that web site is annoying. It appears to be nothing more than a frame with Naudin's own web site:

This has an equally annoying pop-up advertisement for online gambling. Oh, how low we must go to fund this research.

Boy! What should we make of Naudin? He seems honest and well-intentioned, but when he makes claims like this it makes me nervous. I cannot tell whether he has solved the energy crisis at a stroke, or gone off the deep end.

This site has many fine photographs and lots of graphs and data, but no general explanation as to how the gadget is supposed to work, or the experimental method. Here are two general introductions that I confess leave me little wiser:

Perhaps this is a minor issue, but this gadget appears to violate the first law of thermodynamics.

The experimental method appears to be flow calorimetry:

What I do not understand is how and why they manage to keep the input and output temperatures stable while they rapidly vary the flow of water. That seems difficult. They must have a feedback mechanism. Is there a reason they do it this way? Most people use the opposite approach, keeping the water flow as stable as possible while varying either input power, input power plays heater power (McKubre's method), or by letting the output temperature (and cell temperature) fluctuate.
