The art of gentle trout tickling in university hydro project

A group of researchers at Luleå University of Technology is to study eco-friendly, mini-hydro power plants in a tributary to the Torne river, in the far north of Sweden.

Luleå University of Technology (LTU) develops mini-hydropower systems that can be used in small rivers and in parts of larger waterways. 

At Kukkolaforsen, along the Torne River in the far north of Sweden (pictured), a small lateral flow runs by a fishing museum next to the tourist facility in the village. The LTU-scientists are going to test turbine blades, water lubricated bearings and how fish can pass unharmed.

Professor Staffan Lundström of the Luleå University of Technology said: “We want to show that fish and other wildlife remains intact, and that tourism businesses can benefit from our solutions, while the water energy is used efficiently. However, the project is not designed to open roads for the development of our protected natural rivers. On the contrary, a better utilization of water energy in other places will reduce the extension of protected rivers.”
