Whirlpool Turbines Can Provide 24/7 How to Make Wind Turbine Generator 7 months ago   03:16

This whirlpool turbine can power dozens of homes, providing energy 24 hours a day. Belgian company Turbulent have possibly come up with a solution to generate energy for small-scale rural areas. Using the power of water, the turbine can be installed to most river and canals, using the current to produce energy - which the creators claim is enough to power up to 60 homes.

Could this be the future for all energy production?

With 100 liters per second and a height of 1 meter you get a theoretical power of 1 kW, but this thing will have an efficiency of less than 30% so, not even one house, sorry!! Theoretical Power is= specific weight * Q* h= 10000 Nt/m3 * 0,1 m3/s * 1m= 1000 Nt*m/s = 1000 Watt = 1kW

Again it is a simplified form of the Kaplan turbine with a very low efficiency. Given the size of the turbine compared to the bricks around it I doubt that it can power one home. Estimated power less than 1 kW.
Bet it sounds like a toilet constantly flushing, only x10 louder

what happened when i fall in the turbine?

And now a small book on hydro turbine design:

The turbine shown has now "flow regime". You can not predict how water transfers energy to the turbine. Each second is different from the next and all water molecules do not share the same flow pattern as it passes the turbine. It is an average of something not so effective.

The mystery of guided flow:

The free swirl makes the turbine interaction with the flow uncertain.

With the wrong angle to the water the turbine blade will, at best, be a "paddle" obstructing the flow. The forces you get is not by the water following the curvature of the blade but how water curves away in front of an obstruction.

Draft tube:

In the design shown water is droped in open air behind the turbine. So basically the pressure side of the turbine blade is doing all the work and water is wasted with all axial kinetic energy intact. Water even falls some extra distance before crushing vertically into the lower water level!

To extract the energy and use the turbine suction side you need a submerged draft tube to widen the flow to get the speed down. With a submerged draft tube both the extra head and kinetic energy will be recovered as reduced pressure after the turbine.

How about trash and large debris?
the captions shields the most of the content!
you could literally have 10 of these installed close to the ocean, use the tide water to run through it and have a power station close by to collect the energy.
I will buy it for my personal uses now I have an electrcity thats more than average house >:)

brilliant.. I can imagine there will need to be ongoing r&d on filtration at water entry..but very cool

Highly relevant to where the area I am based. In this demo it appears that large part of civil structure has been minimized and that will reduce the cost . I am serious about getting in contact with the company to learn more including establishing partnership for scaling up the into large part of mountainous area where I could see great potential

Just make 3 in a line for free energy. And our up an acrylic panel and a mesh screen at the intake.

woderful.. go green and clean

Aaaaa, well what about the gate which allows water to come in,
Water stops automatically nowdays or what???

Read somewhere this is over $65,000? I think the cost can realistically come down to 10k for the turbine, no? I want to build a tiny house in the mountains but personally think 65k is steep for my needs, I mean they produce up to 100KW, isn't that like 72,000kwh per month, enough for 70 USA homes?

Depends on where you leave in this fully overly regulated Country you would need a Federal. State, County, City permit, if you live in NY, NJ, FL, CA, IL. WA. OR. forget about it and even if one is approved where you are then you got the Federal, State EPAs on your a** and if that ain't enough I'm sure there are a couple dozen of Liberal environmental groups out there that will sue you for stopping the migration of flies, ants, lightning bugs or something else as stupid.

I like the idea. Im no inventor but it lacks a debree filter screen. Potential clogging issues and turbine damage.
The only flaw I possibly see is debris and fish cannot swim up against it
Allen Johnson
If this was on a quite fast steep part of the river you could add one below the other all the way, the same amount of water flowing into the 1st down to the next all the way in the same channel just picking up speed as it goes, You could run a village on a 100mts of the stream.
