heres a not that expensive one to build (im yet to build it tho) http://www.scene.org/~esa/merlib/centripete/
also i just finished scanning a picture from a book on grander+schauberger, this is the hyperbolic cone for creating a vortex. http://www.scene.org/~esa/tratti2.jpg thank you so much for dropping the waterhammer-effect hint, i definitely have to hunt this down. even a brief mention on waterhammer/cavitation would be music to my ears. again, thanks muchly, id never have heard of this had it not been for your post on vortex-list. i believe others on viktorschaubergergroup-list also benefited from this.

Just watching that NOVA program gave me a lot of ideas for building more water vortex generators. I was particularly impressed with the implosion of the tiny bubbles, which caused a water hammer effect. It amazes me that air bubbles can be both suddenly created and suddenly collapsed like that.
