Thanks to reader thruthisimportant for providing this link to a new patent recently granted to Andrea Rossi. For me the link didn’t work, so I asked AI engine Copilot the following question:
“has Andrea Rossi been granted any patents in 2025?”
The answer was “Yes — Andrea Rossi was granted at least one U.S. patent in 2025. Specifically, records show a patent titled “Power supply with vacuum diode” (Patent No. 12438458) issued in 2025”

https://patents.justia.com/inventor/andrea-rossi
An apparatus for providing electrical power to a load includes a voltage source, a check valve that is oriented to prevent current from flowing towards the load, a vacuum diode that includes a cathode and an anode separated by a gap, and a magnet. The cathode and the anode are coated with a corresponding ceramic that includes a titanate group bonded to one of strontium and nickel. The magnet is oriented to cause magnetic field lines that are parallel to a cathode ray that forms across the gap during operation of the vacuum diode. The load is connected between the voltage source and the check valve and the vacuum diode is connected between the check valve and the load such that electric current into the load includes a contribution from the cathode ray in the vacuum diode.
