Unfortunately, it was rejected quickly by scientific communities. At the last attempt to revise the accuracy of the previous researches in this field, a google-funded team tried to examine all the reported documents with their conditions to obvious the claimed results. Finally, they notified that according to those reported conditions, there was no reasonable proof to occur the nuclear fusion reactions. Here, we introduce a method using applying a unique triggering potential waveform as the driving force to a simple two micro-shaft system in both heavy and light concentrate salinity water media that resulted in detecting the 4-helium, gamma ray and heat, repeatedly and reproducibly. In this work, two types of nuclear fusion reactions were observed: 1) D + D fusion reaction in potassium halide salts solutions in heavy water medium without any electrical current flowing through the system and 2) a new type fusion reaction in carbon-containing salts solutions in both light and heavy water media. The only reason to observe the two types of nuclear fusion as well as other by-products was related to the variation of salts. In the latter type, it was proved that the existence of carbon atom in anion structure was critical to observe the 4-He, gamma ray and heat. Besides, the overall light/heavy water splitting was detected as a common reaction in all tested solutions. This study was considered as a new method based D + D cold fusion with significant advantages such as high sensitivity, acceptable reproducibility and adequate repeatability. Accessing to such a set-up system would cause significant progress in the future of the green energy.
