levitational current - Free Energy

At their extreme development, these air masses take on the more
physical form of a tornado or waterspout. With their source in the
lower density air mass subjected to solar radiation, as they descend
with increasing velocity they become denser and more physical. The
core of some tornados becomes so dense they can bend railway
lines.
Viktor Schauberger found it hard to understand why science has
not ascribed any fundamental importance to the natural movement
of energy and Nature's systems of spiral movement, which are so
clear, from the scale of a galaxy to that of a DNA molecule. Perhaps
this is because it has been too immersed in the Euclidean elements
