This is the first new solution for hydro-power I've seen in years. No moving parts (meaning nothing under the water surface that if there's algae or barnacle growth the bearings will seize up.) I can see using a larger one on a sail boat, or having a set of impellers. You could have different impeller sizes depending on the wind. The thing about sail boats is they have a fairly narrow speed range, so 10-11 knot winds you're going 5-6 knots, drag something in the water and lose a knot, At 12-14 knot winds you're still going 5-6 knots but dragging an impeller does nothing(except generate power.) At 18-20 knot winds, maybe you're going 7-8 knots, your sails are reefed and an even bigger impeller, generating more power, still doesn't slow you down. The way sailors do this now is with a folding prop - that doesn't spin as well as a non-folding (but minus 1-2 knot) propeller or they use a completely separate device that drops in and out of the water. Most hydro-generation mechanisms look like they'd soon be fouled. They're big and expensive, I always see the project announced, sometimes the device place in the water....and then.... nothing.

I don't really understand what you mean in the second and third step with "let that river run". Do you have a resource you could share where what you said is more detailed, please? Thanks!

Hallo DW, wo kann man so ein Mini-Kraftwerk kaufen?

[@misteryman5109]

Only €299 ?!?!? What the f*ck?!?! - I spend that much for electricity for my household of 4 for 6 months. The thing is made out of plastic, I cant imagine it would last more that 3-4 years under daily constant use as the plastic will degrade over time due to thermal expansion. Even if this would be made of molded aluminium or powder metal the seals would needed to be replaced every 2-3 years to ensure water tightness. Again €299 ?!?!? and it will generate maybe €30 worth of electricity over it's lifetime. TOTAL JOKE!!!

[@Shockwelle1]

typical germans, evrything so much expensiv. they dont want to help poor countries and people, they want to their money all of the money. greedy germans, shame on them. u gues in that turbine are 4 Lithium batteries +ba simplecircuit board + plastic cover + turbine, shpuld be all worth 20-30e euros. total scam, total greednes, typical germans

[@compasteedee]

It isn't about the monetary value of the electricity it is generating, it is about generating electricity in situations where it is needed, but otherwise unavailable.

[@angrydragonslayer]

@@compasteedee turbulent (company name) has a system running in a comparably sized waterway to this one which generates 15 kw a 1.5 kw turbine from them costs ~$1500 but will last for 15-20 years with simply hindering debris from blocking the intake

yea there is something that should produce elektrik power it schould be as light as possible and should not sink in water aluminium perfekt its used for kables and its heavyer so you can carry more and the best thing it will sink like a stone perfekt 😂 by the way plastik can last extreamly long and that stuff needs to be produced and transported...

Yes you can take it anywhere to charge your phone! Just add a fast moving stream... and stand there holding it, making sure it doesn't hit the bottom or some twig floats past and stops it spinning... Africa has sunshine lots of sunshine. Its everywhere too. Streams are not everywhere....

The limiting factor of how many kwh it can create in a day is the rate at which the generator can recharge the battery, not the particular battery's size.

$340 when the turbine with voltage regulator can be bought at less than $10 with free shiping. So you pay more than $330 for the plastic enclosure and cabling? These are not german enginners, they are simple scammers!

It won't work very well either. It looks like something you'd buy in Walmart because it's very cheaply made. Also, imagine if everyone in the village had one and were all trying to put theirs in the stream! They would get tangled. I noticed how they showed it working in the middle of a stream maybe 18 inches deep! Not floating at the top or sinking to the bottom. That reeks of trickery to me.

[@john9972]

@@tarstarkusz it has to be submerged to work efficiently.

[@tarstarkusz]

There is some quick video which shows the turbine in what appears to be about 1/2 way between the surface and the bed. That turbine is not going to want to sit there. It is going to want to either float or sink to the bottom.

I notice that they carefully don't say the power output of the device shown. with only the kinetic flow in the creek, and the tiny area, it can only put out a few watts- ten if you're lucky, maybe enough to charge a cellphone. A 500 watt turbine is much larger, about a foot in diameter for a high-head design, and needs a significant investment in a feed inlet, delivery tubes, valves, and electrical conditioning equipment with charge controller, batteries, and inverter.

This is amazing for camping or if you live near a river or creek. The water will always flow 24/7, no matter the weather, condition, time. It’s literally more reliable than wind or solar. There is much potential here. Too expensive at first, but this could become affordable eventually. 500watts is a lot of power for low voltage usb-lights so yes it can power a village. Do some research on solar lamps in Africa. A hand crank generator 60watt is about $300 for comparison, but those require energy (from you). No other type of clean energy can be so consistently reliable 24/7

[@coltonjacobs5383]

Correct me if I’m wrong but, isn’t it just a motor shaft connected to a wire connected to a propeller? Of course their is the battery and circuit board but those don’t cost much at all to make. That thing is worth probably $120-$180 at most
