Interview of Akito Takahashi by Steven Krivit, August 25, 2003, Cambridge, Mass. (MP3)

Dr. Takahashi performed successful excess-heat-producing experiments which were subsequently replicated by Dr. Edmund Storms and Dr. Franceso Celani.

Gene Mallove reported this research as follows:

"On January 27, 1992 at the ISEM IEEE meeting in Nagoya, Japan, Dr. Akito Takahashi of the Department of Nuclear Engineering, Osaka National University, reported spectacular results. Takahashi's device is a 1 mm thick x 35 mm x 35 mm palladium plate. Over a one-month period, the device put out, on average, 70 watts of excess heat. About three times more heat energy came out of the device than the amount of electrical energy put into it. The total excess came to more than 200 megajoules of heat, or approximately 15,000 eV per atom. This is thousands of times more heat than any chemical reaction could possibly produce.

Dr. Edmund Storms of Los Alamos National Laboratory announced on August 15, 1992 that he had successfully replicated the Takahashi cold fusion experiment. His experiments were conducted using a palladium cathode. Dr. Storms' success was published in Fusion Technology. Several other groups are known to have replicated the Takahashi experiment with varying degrees of success, including the group of Dr. Francesco Celani in Italy."

Takahashi 1992 Paper: "Anomalous Excess Heat by D2O/Pd Cell under L-H Mode Electrolysis."

ABSTRACT
A Pd sheet cathode centered within a Pt-wired anode in D2O/LiOD electrolyte was used with the L-H mode pulse operation. Anomalously large excess heat (32 watts on average for 2 months, 100 - 130 watts at peaks and averaged output/input power ratio 1.7) was once observed, associated with very low neutron emission (~1 n/s). To investigate the reproducibility of this experiment, a second experiment with minor changes in cell design was undertaken for 4 months. We reproduced excess heat, however at much smaller levels (8 watts on average and 15 watts at peak), but with neutron emission rates that were twice as large as measured previously. Possible changes in the conditions of the two experiments are discussed; i.e., cell voltages and over-potentials, formation of thin MOS film on the Pd cathode surface and a mechanism enhancing the D/Pd ratio. Excess power density per cm2 of cathode surface showed systematic change as a function of surface current density. This trend is consistent with results from many other authors.
