"Fish Friendly" Gravitational vortex demo has big surprises!






Cheap little demo about the amazing gravitational vortex power plant. (This video won a prize in the Instructables Summer's Water Challenge). (Fish friendly low head hydro power from Austria). VERY counter intuitive stuff! Various people have now confirmed (including my bilge pump maker!) that this set-up: 15 Watt solar panel powering a 600 gallon per hour 12 volt dc bilge pump NO BATTERIES! will not cause damage to either panel or pump and it will come on automatically in the morning when the sun rises high enough and shut off again in the evening or really dull weather. Some people really liked it at Maker faire Victoria. Among them a nuclear physicist.
Video Rating: 5 / 5

  1. Yeah, I will change it. Thanks for you input on ideas vic too. It was very helpful.

  2. Oops, accidentally deleted my original. Yes, I thought it was about free energy because of the set up, but I see it is a prototype and presumably, it production it would use gravity (a river, stream or dam) not electricity! to produce rotation and/or electricity. OK. Sorry about that. Fish friendly and other low tech design advantages should be highlighted in your description so people don't this it is about free or mystical energy... ;-)

  3. Physics is alive and well. It is not a free energy device. Sorry.
    Physics should spend some money on developing low end stuff like this and the pulser pump, the "mechanical mathematician" the solar design t-square and clam shaped solar cookers. These need research to be more usable and help a billion people have better lives! The Higgs Boson cost over $10 billion just to find! Politicians like to fund BIG SCIENCE. Practical science needs funding too. Little questions need answers too!

  4. Nice. Figure you could then drop that outflow into an Archimedes screw and tap off the rest of the potential...

  5. "Water is practically incompressible"

    That's not entirely true. Water is at it's most dense at 4 degrees and as it raises and lowers from that temperature it becomes lighter. Hence an ice cube floating in water.

    Yeah sorry I might not of been too concise in my answer. The turbine will interfere with the natural motion of the centripetal force.

    A decrease in velocity creates an increase of pressure and vice versa.

  6. Water is practically incompressible. We had lots of people look at the model in Makerfaire today. Nearly everybody guessed that the water level would rise when you put a turbine in the vortex. Very sunny day so I had to tilt the solar panel away to keep the water slow enough. A nuclear physicist looked at it and liked it! I had some southern Germans pronounce the inventors name. We discussed powering a wire gyrating can can girl (above it) with "Nancy the blacksmith". She said NO.

  7. Thanks for the explanation.

  8. vortices are centripetal in nature, not centrifugal. The reason for the overflowing of the water is because of the change of density at the 'focal point' of the vortex. As the water spins centripetally it compresses into itself (fractals). This is natures basic motion.

    Concluding that due to the increase of pressure and density of the water, the hole is just no bigger enough to handle that output.

  9. Really awesome. Thanks for the captions, maybe at first you could add an advice "Turn on captions" for those as me, that can read English.

    I think the explanation for this is that the vortex, being centrifugal, obstructs the water output. When you obstruct partially the vortex, the water output increase. But it is only a guess.

    A power regeneration turbine for a necessary event for aqua culture. Very cool man.

  11. Well from what I have seen, the water slows down going through the hole as a vortex builds up over several minutes, and the water rises in the little bucket. That would mean that the vortex is accumulating energy from the falling water. I have also seen it with my "turbines". I can have the water going through the hole (no vortex yet) and as the vortex builds, it tugs harder and harder on the biggest "turbines". Anyway, the only way to be sure is to test it yourself.

  12. I'm not convinced that it's an energy-in-the-system thing yet. Could it be that the turbine changes the direction of flow of the water to be more vertical and thus drain faster?

  13. I think Franz Zotlöterer is brilliant but knowledge of his work is just not spreading quickly enough. Unfortunately he speaks German with a heavy Austrian accent so your second link has the most awful translation to English I have ever seen. (Anyone want to translate it better?)

  14. Look at the work of John Cadman... /watch?v=yRsEhgZLZ8A

    And I see that you're already aware of this video... :)

    watch?v=2plJ3C-SOq4

    These are "bio reactors". A very good idea to drink the water coming from it too!
