Sine wave inverters with more than three steps in the wave output are more complex and have significantly higher cost than a modified sine wave, with only three steps, or square wave (one step) types of the same power handling.
A healthy cell has a pH of 7.35 while a cancer cell is more acidic. Cesium when taken orally will raise the pH of cancer cells, but not that of normal cells. When the pH of a cancer cell goes above 7.5 it dies and if it goes above 8.0 it will die in a matter of hours.
This process is the opposite of trying to kill cancer cells by increasing pH levels. It is much more effective because it uses what the cancer cells produce, lactic acid, to kill the cells, as opposed to trying to make cancer cell pH more alkaline, with alkaline minerals, alkaline water and so on.
