When Hydrogen shrinks to form a second level Hydrino (Hydrogen itself is considered to be the first level Hydrino), about 41 eV of energy is released. This is already about 16 times more than when Hydrogen and Oxygen combine to form water. And it gets better from there. If that newly formed Hydrino collides with another catalyst atom, and shrinks again, to the third level, then an additional 68 eV is released. This can go on for quite a way, and the amount gets bigger each time. Here is a table of some level numbers, and the energy released in dropping to that level from the previous level, IOW when you go from e.g. level 4 to level 5, 122 eV is released. (BTW larger level numbers represent smaller Hydrinos).
Level
Energy
2
41 eV
3
68 eV
4
95 eV
5
122 eV
6
150 eV
7
177 eV
8
204 eV
9
258 eV
For those of you with a mathematical bent, the formula is ((2 x n) -1) x 13.598 eV, where "n" is the level number.
(BTW the maximum level number is certainly no larger than 137, and may well be less than that, not least because when a Hydrino gets very small, it may undergo fusion reactions with other atoms.)
Of course, the numbers can be added up. IOW if you start with a Hydrogen atom, and end up with e.g. a level 5 Hydrino, then you get a total of 41 + 68 + 95 + 122 = 326 eV.
The total for any level can be calculated with the formula (n^2 -1) x 13.598 eV.
