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 causes the pH of the cell to drop from between 7.3 to 7.2 down to 7 and later to 6.5 in more advanced stages of cancer and in metastases the pH drops to 6.0 and even 5.7 or lower. Our bodies simply can not fight disease if our body pH is not properly balanced.
