In patented double-spiral-flow pipes the peripheral water-masses are caused to swirl within and about themselves and around the central pipe-axis. This produces differences in potential between the peripheral and core waters, which lead to an accelerated flow resulting from the energising and ennobling of the bio-dynamically moved water.
