The realization of energy-dense artificial fusion energy on Earth is the most desirable solution as an environmentally friendly primary energy source. After 34 years of cold fusion research since 1989, we have arrived at a great solution: New Hydrogen Fusion Energy (NHFE). NHFE is a clean and portable form of fusion energy that uses light hydrogen...

The main MHE power generation pattern can be explained by the nuclear energy release of 4H/TSC WS fusion events at T-sites of Ni nano-cores. The release occurs when dynamic 4H cluster formations of 4 protons move from O-sites under phonon excitations in GMPW (global mesoscopic potential well) of Ni-nano-islands. This is the major process of power (...

I have found the following conclusion. From understand...

This site was once removed accidentally by mishandling, and now re-uploaded. It’s surprise now that the H-gas loading run to nano-composite Ni catalyst systems (as reported from MHE-Kobe, Tohoku U, and also from US, French and China groups) do produce similar amount of excess power as the D-gas loading does, particularly/efficiently at elevated tem...
