This unique concept unlocks the potential for electricity generation in low volume waterways such as a stream or a brook. Opening up a whole range of unexplored sources of sustainable energy in many areas of the world. The rolling fluid turbine is a viable alternative to conventional hydroelectric generators, which have been providing power from water since they were developed in the 1880s. Typically hydroelectric power requires a huge head of water to function, relying on blades submerged in high-velocity water streams. The rolling fluid turbine relies on physics to convert water's natural flow into upward pressure to generate electricity, this promises to change how water current is transformed into electrical power.
This is achieved by exploiting a unique hydrodynamic principle, the rolling fluid principle vortex dynamic, which can create a large amount of energy. This is achieved by using the naturally occurring suction of water by driving it through a specially shaped turbine casing, Sedlacek and his team have managed to generate power with an output of up to 10 kWh per day at 60% efficiency from a small turbine. This is enough power to meet the requirements of 5 European families or an entire African village.
The invention is a tubular canister that floats like a buoy on the surface of a small body of water. Beneath the surface, the natural flow of water is directed through a tube driving the water pressure upwards with increased suction as a result of the vortex principle. Inside the turbine shaft, the vortex energy rotates a cup mounted on a generator shaft that converts the rotation into electrical energy.
When installed in a slow moving stream, the turbine can generate energy for a small house at levels of up to 400 watts. Ideally, the bladeless turbine operates more effectively at flow levels of 22 to 250 litres per second, but it can produce results in flow rates as low as 2 L/sec.
The mechanism is unclear, but other designs exist that convert low-head flow into electricity.

Images on posts? I believe I speak for everyone here when I say fuck that and fuck you.

Once we enter the realm of graphics, there is no turning back. Now, Soylentils can convey their meanings by symbolic communication, this thing we call "language", and more specifically written language. Just think of it! Symbols that stand for sounds, that stand for ideas! Amazing! But if we allow image posting, or even more insidious, video, no longer will Soylentils be able to commune at the level of ideas.
We instead will be sucked into an emotional vortex of spinning water with pictures of Marines, and Trump cabinet members, and all possibility of communication on the level of ideas will become impossible.
So, think, those who would want a (img src) tag, do you really know where that would lead SoylentNews? Is the convenience of posting your revenge porn worth the destruction of the last sane forum on the internets?
