An interesting patent application was linked on the Cobraf forum on May 29 2016, 21:55. The inventor is a researcher called Giuseppe De Bellis, from Ferrara, Italy (which is where Rossi was located in 2011-2012). It's been noted that it has a canadian patent application with an applicant located in Cyprus and therefore that it might also be related with Defkalion people.
It's possible that the patent might be describing something similar to early E-Cat devices.
An exothermic transmutation method for at least partially deactivating radioactive material, the method comprising the steps of: - Arranging a dusty compound comprising at least a transition metal in a chamber (7) of a reactor (1) outside a closed container; - Arranging the radioactive material in said chamber (7), the radioactive material being and staying encapsulated in said closed container; - Providing hydrogen in contact with the dusty compound and with the radioactive material at a pressure higher than the ambient pressure; - Generating an electric field in the chamber (7), the electric field being applied to the dusty compound and the radioactive material; - Energizing the dusty compound by heating, then generating a transmutation of said at least one transition metal into another transition metal and proton emission towards the radioactive material, said radioactive material being at least partially deactivated, - Removing thermal energy from the reactor (1).
The patent is relatively detailed. It also claims that Sergio Focardi performed some calculations.
Theoretical calculations of energy productivity, carried out by Professor Sergio Focardi (Nuclear Physics, University of Bologna), offered a COP value equal to 463 (value significantly higher than that recorded during experiments, which are preliminary).
There also are details like:
Attempts based on Ni62 in a copper tube with hydrogen have been made. The energy production was below expectation.
