German inventor presents self running water wheel on TV

[Cloxxki]

It's old hat. Look on you tube there are simpler ones than that pumping gallons far up hills
from ponds and Rivers. Most of them are Asian vids, Perhaps we can learn from our Asian
friends.

Sil

If the Asians show drawings and parts, they might be as open as these Germans.
Since these guys are putting themselves out there laying parts bare, perhaps they deserve this forum's attention?

Have you specifically seen vacuum to bring OU results?
I have some mega scale water pumping applications in mind for which self running pumps would be half of the solution.

"The Heligrimo pump is a patented innovation on the pump market, with a very wide range of applications, self-priming, temporary dry running possible without venting, very energy-saving minimal size and environmentally friendly.

The speed of the pump can be controlled as required and is characterized by extremely high flow rates at the lowest speeds.

Do you prefer first-class quality and individual solutions?
Then you are exactly right with us.

Above all, Heligrimo stands for the manufacture of high-quality pumps and excellent service.

Take a look around our website and convince yourself of our unique offer.

We are a "young" start-up company, currently still in inventor status. Our patented high-performance pumps are energy-efficient, indestructible, easy to maintain and are characterized by a high level of efficiency.

We are still looking for investors for series production and expansion of sales."

Very short synopisis of presentation for non German speakers:

Former ship captain came to his passion for pumps when his ship needed a pump and there was no way to source one in time. He put something together with parts available to him.

Supposedly has customers lined up in Scandinavia.
Delivery time 4 months.

The wheel drives an electric motor which runs the pump.

It takes a manual start and from then the wheel just runs.
He's been working at this for 30 years, the other gentleman has been helping out for the last 2.

This is remarkable.....how to manifest a gain mechanism which would self run and make more power?
(Victor Schauberger ?)

And we should be able to visit him to purchase?
Going to see if we have anyone close by who could get a demonstration of it working.

Thanks
Chet

Well, I just got an email from a friend, that he himself visited these 2 inventors a few years back..
There the machine did not work yet selfrunning...
Maybe they are still working on it ??
He also doubted that they will get it to selfrun..
I tried to call just now the TV station, but today it was already a bit too late in the day...

Will try again next week.
Regards, Stefan.

Thanks for your efforts, Stefan!

@Anyone: What are the losses usually seen in conventional pumps tasked to overcome vertical distance?
If they are close to unity with a very unrefined water wheel, the pump itself might still be exceedingly efficient.

Say, there may be an anomalous situation with limited back pressure from cavitated water pumped up <2 meters.
Especially with that down pointing final exhaust. Assuming the water has lost most of its cavitation by then, the water coming down over the top is denser than coming up towards the top at the same level.
The idea of introducing at at one or more points after the pump fascinates me, I wonder whether they do that. It's the kind of situation many will encounter but perhaps few will never know, because there would be no visible spillage. Even withy the pump pushing and the water weighing itself down, at the point of the least, the pressure of the water may well be under 1 bar and this suck in air. De-cavitation occurs, but without the associated density increase. You'd be pumping water up higher for the rating of the pump motor, but how will water volume be affected? Does the pump motor feel what happens downstream, through a volume of capitate outflowing water?
I suspect a narrower pipe after the pump will be advantageous to speed up the flow and get the vacume to exist for longer (and higher).

I'm sure some of the brilliant minds on this forum will know ways to rapid prototype such a pump and test it against conventional designs. It's water, everyone has the best fittings on hand! :-D
