Miroslav Sedláček once noticed that the leaves of the trees are spinning along their axis in the water vortex against the direction of turning the whirlpool. You can also observe this phenomenon at home in your bath when discharging water. At some point, a vortex develops and the water begins to spin. It is this hydrokinetic energy that converts the Sedlak Turbine into electricity. Its advantages are that it can also be used on streams or sewers. For his invention, a scientist from the Faculty of Civil Engineering of the Czech Technical University in Prague is nominated in the research category at the European Prize for Inventors of the Year 2016.

Miroslav Sedláček, together with his colleagues at Vladimír Novák and Vaclav Beran, worked on the development of a liquid turbine and obtained a patent for it. Their liquid turbine can also generate energy from slow-flowing streams, brooks or from sea tides and outflows, which is a revolutionary alternative to adding resources to power from conventional hydropower plants for which a considerable flow rate or high waterfall height was required. A liquid turbine can produce up to 10 kilowatt hours of electricity per day from slowly flowing streams, which is sufficient to cover the electricity needs of five households. A turbine can provide electricity in areas that are not connected to the mains.
