Using a Van De Graaff (VDG) machine, we can easily generate million-volt high voltage. The high potential difference can be generated effectively with minimum energy supplied to the machine. The larger the volume of the machine would be, the higher the voltage could get. However, stability would be a problem when the voltage gets to over 10 million-volts. This issue could be resolved with ‘magnified’ machine design. For example, VDG1, VDG2, VDG3 è VDGA VDG4, VDG5, VDG6 è VDGB VDG7, VDG8, VDG9 è VDGC … VDGA, VDGB, VDGC è VDGX In that case, VDGA works like a magnifier which aggregates the positive charge (or negative charge conducted from smaller VDGs) and collectively ‘magnifies’ the voltage to higher voltage. Of course, a portion of the positive charge could be lost in the process. However, it could theoretically be possible to keep majority of it until the voltage gets elevated to 100 million volts or higher. With such high voltage working on the deuterium or tritium, gas mixture which could be mixed from a source of gaseous catalyst, selected from the group consisting of beryllium, carbonates, hydroxides, halides, sulfates, phosphates, and sulfides. The reaction produces natural lightning, or occasional fusion reaction if you like.
