A new report from Sapporo Japan claims increased excess heat from a Nickel Reactor.
Modifications to the cold fusion energy reactor designed by Tadahiko Mizuno have dramatically increased excess heat production. The thermal power output of the cell is now able to exceed the air-flow calorimeter’s heat removal capacity of 1 kilowatt.
This is reported in the paper Increased Excess Heat from Palladium Deposited on Nickel [.pdf]. Co-author Jed Rothwell will describe the spectacular results at the 22nd International Conference on Condensed Matter Nuclear Science ICCF-22 this September 2019 in Assisi, Italy.
When the input is 300 Watts heat, thermal power output is estimated to be between 1 – 3 kilowatts. This is based on the fact that Prof. Mizuno heated his room in Sapporo last winter with the cold fusion reactor, and he felt the room’s temperature to be as warm as when using a 3-kilowatt electric heater.

The jump in power occurred after he placed the heater that regulates the reaction at a new location inside of the cell, as well as new and different applications of pressure to the reactor.
But he also changed the way he made the active cathode material.
Physically Rubbing a Nickel Mesh with Palladium
Previously, to produce active nickel-mesh cathodes Prof. Mizuno, lead researcher at Hydrogen Engineering Application & Development HEAD, had been using glow discharge to “erode the center of the palladium electrode and sputter palladium on the nickel mesh”. This method could reliably generate 232 Watts excess heat with 248 Watts input, but it took months of applying the discharge to complete an active cathode. He needed a new method of applying palladium to the nickel-mesh.
Old cruciform design used glow discharge to prepare the cathode for a reaction. Excess heat was reliable, but the whole process took months. Graphic from Excess Heat from Palladium Deposited on Nickel.
Electroless deposition gave good results, but the chemical solution was expensive. So, Prof. Mizuno started physical rubbing a palladium rod on the nickel-mesh to save money.
Three separate nickel mesh pieces are prepared by rubbing “vigorously” with a palladium rod. A careful WARNING is included: the procedure should take place in a glove box or appropriate facility as the fine particles of nickel dust are toxic and pose a health danger. Only those “skilled in the art” should attempt reproduction.
