German inventor presents self running water wheel on TV

[Cloxxki]

Actually it is clear that the wheel is to heavy for the water to make it move. That is why he is using the crank to bring it up to speed. The german text then says that once it is at speed, it produces enough electricity to run the pump, which then pumps enough water to keep the wheel running. I suppose it cannot really produce a lot of extra energy, and that the people buying it in the scandinavian countries will probably have a nicely spinning "waterwheel", but i cannot imagine that energy production will go much further than maybe load a phone. it is a little like the inventor interview for the lüling motor. The inventor was enthousiastic, like this one, but the system never went into production.

Ok, i think those two builders are in good faith, but analyzing what i have seen, it think the guy spinning the wheel with his crank, gives it so much kinetic energy that it will spin a day or more (being very heavy and the water pump helping)

Cant wait to hear Stefans feedback after he visited the 2 inventors!!!

What they are showing hardly looks like an optimised system. If that thing can only produce water splatter and a phone charge, then surely in that same reality there is rool to optimize the liquid being pumped, water-to-wheel interaction, ideal pump flow wheel height and (independently) radius ratios, pump rpm, pump geometry, pump housing and blade surface patterns, etc, etc? Any such opimizations from what a couple of German blokes threw together would elevate the output to change a phone (say, 1-5 Watts) to a decent percentage of the pump's power which seems significant, maybe around the kW range?

I think, it either doesn't self run, or it can do so easily with refinements and with worthwhile output. It seems it will never have a high power density, as it relies on a big apparatus and just a bit of water coming down a small height difference under the weak force of gravity.

If there is indeed a gain, it seems it must be on the overcoming of gravity side, else the waterwheel would surely have been an enclosed turbine relying on pressure rather than potential energy?
At the moment I can only imagine a gain if the way the pump worked and were hooked up to inlet and any amount of exhausts or ambient air inlets, to somehow do better than the mathemetical flow possible for the power driving the pump.
I'm no builder or even published academic, but I can only see a gain for a "vacuum" pump when it cleverly interacts with ambient air, which is the abundant factor in this system.

Is the pump really vastly more efficient than traditional pumps, more than 100% efficient? A water wheel that doesn't need Mr. Hand would be convicing, but we've not seen it without Mr. Hand.
Let's all hope Stefan will soon be fit to travel to Bavaria and meet with the inventor and learn about it what he's able to. If I had a car, I might have done the 800 km drive there just for fun. I don't even need an OU invention as an excuse to be in Bavaria, I love the mountains and cross-country ski trails there

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.

To improve the efficiency of this machine:
Take the height at which the output water impacts the wheel with a downward force,
and go to the back of the machine and cut the pipe off at that height.


Any height above this, you are simply wasting energy lifting water against gravity, then recovering a percentage of that to assist in driving the wheel.
This is nonsensical. It is better to use it as is, without trying to feed the water back in.

well, very strange. the same day i read about this water wheel device here (and saw the video stefan had uploaded to yt),
there was a program on austrian tv called "2 minutes - 2 millions". they have the same in other countries, in germany its called "Höhle der Löwen" - "The cavern of lions", in the states its "shark tank" and there is also "dragons den" i think in canada.

Anyway here in Austria there was an old man and his granddaughter presenting his invention to a group of investors. Actually the invention was a "solar steam engine water pump". (i continued watching because i was still under the impression of this pump video here).
They had to pixelate the pump because he was waiting for the patent, but to make a long story short, he convinced one of the investors to give him 500.000 euro. Actually its an easy running waterpump like this one, but its driven with, what he calls a modified solar cell steam engine. the cell is about 2 square feet, it does not generate electricity but it simply heats a very small amount of water to produce steam, and this steam makes the pump run. so its a sort of "solar steam engine".

if someone is interested i am adding the few pics of the device here (those that are not pixelated) but somehow if the pump we've seen above is so efficient, it would run like hell with this device.
Here is what I know:
its got (a future homepage) https://pumpa.tech
the tv program it was on:
https://www.puls4.com/tv/2-minuten-2-millionen/staffel-10/episode-01/pumpa-im-pitch
the video there is only the part where they present the pump.

its in german of course, and there are 2 commercial blocks embedded, sorry thats not my call.

Basically for the non german speakers, she is explaning that the system uses about one glass of water that is heated as steam, and runs the steam engine that is producing electricity to run the pump. The guy that invests the 500.000 € is hans peter Haselsteiner, an austrian billionaire, one of the richest men in the country, he has a very big international construction company (so the 500.000 are peanuts for him).
I will certainly keep on watching this.

Sorry i didn't want to spam this thread, but i thought it might be interesting until stefan as visited those 2 inventors of the other pump.

Seems that way to me as well. Although I'd rather see a taller wheel to make up the full height.
In my fairy tale version where the vacuum pockets in the water and/or air bubbles let in on the way up play a role in lifting the water higher than a normal pump would, there might be a case to take the water as high as it goes.
Any downward pointing outlet pipe might play a role in pulling low pressure inside the rest of the pipe. With more vacuum bubbles collapsing further downstream, the water exiting downward would be denser than the water coming up. Quite a theoretical stretch, and the prototype doesn't seem to actively make sure of any special flow dynamic, it just had water coming out being aimed at the wheel below and that's it.

I'd love to see a well matched and tuned off the shelf pump substitute theirs, for a comparison in in runtime or manual start input. If the water wheel would be running day and night like a champ, it wouldn't matter much but still interesting to know how much better it were to be.

We canceled the Visit, as they also don't want any new visitors anymore and it was said, that the old inventor now has dementia and can no longer work on it....
So this project seems to be dead and did not selfrun...
Was probably just a media hype of theTV station that made the video...
