After the release of the new Third Party Report, it was a spontaneous curiosity for me to compare quantitatively different energy sources to see where the Hot-Cat fuel ranks.
I found very useful, in order to make such an assessment, the chart published on the website LENR for the Win and given here. It is a so-called “Ragone chart”, used for performance comparison of various energy-storing devices. Both axes are logarithmic, which allows comparing performance of very different devices (for example, extremely high and extremely low power).
On such a chart the values of energy density (expressed in Wh/kg or, after an appropriate equivalence, in J/kg like in this case) are plotted versus power density (in W/kg). Conceptually, the vertical axis describes how much energy is available, while the horizontal axis shows how quickly that energy can be delivered, otherwise known as power, per unit mass.
It is interesting to note that, in the 2nd Third Party Report (TPR) by Levi et al., the Hot-Cat fuel showed to be about an order of magnitude more “powerful” than in the 1st TPR (see the chart). Also renewable energy sources such as solar panels and wind plants, although imperfect candidates for inclusion in a Ragone chart, have been included for comparison.

So, Hot-Cat fuel can be compared with a powerful nuclear source such as Plutonium-238 and the most common Uranium-235 (an isotope of Uranium whose fission in chain reactions is used in fission reactors), which appears to have a much lower power density (at least a factor 100 lower) and an energy density substantially similar.
All the traditional fossil energy sources (such as natural gas, coal and so on) have instead, compared with the Hot-Cat fuel, a significantly lower power density (a factor 50 lower or more) and a much lower energy density: at least 4 orders of magnitude lower!
So, it is quite obvious to consider the reactions behind the operation of an E-cat not chemical reactions, but rather a new type of nuclear reactions, although occurring at low temperatures and without dangerous or polluting by-products. In short, they are a form of LENR.
