Viktor Schauberger's Logflumes on YouTube

from YouTube:

In the 1920s, the Austrian forester, hydraulician, hydrologist and inventor Viktor Schauberger developed an entirely new view of water as the "carrier of all life." As an "ecotechnologist" he also translated his amazing discoveries into fact, and enjoyed European-wide successes in hydraulic engineering, while his inventions for improving water quality created an international sensation. Today, after decades of obscurity, disregard and suppression, his discoveries are receiving the attention they deserve.
