So far, raising power from flowing water was quite problematic. It was necessary to build a very expensive and complicated firewall, pile up water and only use the supplied by energy. Change is due to a revolutionary unit called VIVACE, which can recover energy from freely, slowly flowing water-just toss it into the water, on the bottom of the river.
This device is developed with having its origins at the University of Michigan startup Vortex Hydro Energy, weighs 12 tons, and now it is no longer the last prototype, on a scale such that they possibly will go later to the market.
And this device can completely revolutionize the, although it looks quite inconspicuous this steel frame 5 wide and high on the 3.5 meter, where the rails are placed vertically four aluminum cylinders. These cylinders are moving silently carried even very slow current River, and each of them can get the power of about one kilowatt.
This is the first device that uses the devastating phenomenon of turbulent flow when the water formed the miniature vortices, which enhanced resonance move cylinders in one and in the other direction. On paper it looks like it could be quite straight, but in the phenomenon for years wondering to scientists from all over the world.
80 thousand times better results is we will deal with vortexes instead of flow
They thought they over this so strongly, because this phenomenon is very common, is literally everywhere, and if you will acknowledge that VIVACE works on an industrial scale is going to have to deal with yet another revolution in the energy industry. We will be able to get electricity from almost every river and a fairly low-cost and with minimal environmental impact.
In numbers presents a very promising wind farms generate about 0.01 cotton on occupied cubic space with wind blowing at a speed of 12 meters per second, VIVACE achieves a similar water flow capacity 800 watts per cubic meter and so 80 thousand times (!) a better score.
We look forward, therefore, looking forward to the tests of the prototype.
