A new paper has been published on arxiv.org titled “Nucleon polarizability and long range strong force from σI=2 meson exchange potential”. The authors listed are Carl-Oscar Gullström and Andrea Rossi; report available here: https://arxiv.org/pdf/1703.05249.pdf
The physics involved are very complicated, and I will not attempt to critique it. However there is a very interesting experimental report of a device tested in Doral, Florida, which from reading it would have to be the QuarkX that Rossi has been talking about for so long (although the name QuarkX is not used). Below is the section of the paper describing the experiment:
REPORT OF THE EXPERIMENT MADE ON MARCH 7 2017 IN THE LABORATORY OF THE FACTORY OF LEONARDO CORPORATION
Address of the site: 7861 NW 46th St., Doral, Florida, 33139 USA Participants to the experiment: Carl-Oscar Gullström, Dr Andrea Rossi
Description of the apparatus The circuit of the apparatus is made by a power source to supply direct current, a load made a 1 Ohm resistance, a reactor containing two nickel rods with LiAlH4 separated by 1.5 cm of space.
Measurements: During the test a direct current was switched on and oﬀ. When the current was switched on a plasma was seen ﬂowing between the two nickel rods. The current was running through the plasma but the plasma was found to be charge neutral from a Van Deer Graaf test. This implies that the plasma has an equal amount of positive ions ﬂying in the direction of the current and negative ions(electrons) in the opposite direction.
Input: 0.105 V of direct current over a 1 Ohm resistance.
Energy output: The wavelength of the radiations out of the reactor has been measured by a spectrometer ( Stellar Net spectrometer 350-1150 nm ) and was integrated with the value of 1100 nm ( 1.1 microns ).
The temperature of the surface of the reactor ( a perfect black body ) has been calculated with Wien’s equation: 2900/λ (micron) = 2900/1.1 = 2636 K
By Boltzman Equation the eﬀect is: W = σ × ǫ × T4 × A
A = 1.0 cm2
ǫ = 0.9
By substitution: W = 5,67 × 1012 × 0.9 × 4.8 × 1013 = 244.9
A simple calculation using Ohm’s Law (.105 V / 1 Ohm = .105 A) gives the input power of 0.01102 Watts (.105 x .105)
To calculate COP: 244.9 (W out) / 0.01102 (W in)
COP = 22,223.23049
If confirmed, this is much more impressive than any previously reported E-Cat test.
