Biraj Gautam and Rabin Shrestha share their lessons from the latest visits to the micro hydro power sites in Jumla and Baglung.
Concrete Turbine Manual video from our partners at Janathakshan
Our partners at Janathakshan in Sri Lanka have made a video to describe their low-cost, easy to assemble pico-hydro concrete turbine. As of February 2014, this turbine has been deployed in 45 Sri Lankan villages, of which over 85% are still functional.
The casing for this turbine is built from concrete, while the runner is constructed from aluminium and fibre glass. The turbine efficiency is about 70% and it possesses a number of advantages over its steel counterparts.
In order to share their micro-hydro technology, Janathakshan have made a video demonstrating the steps required to build the concrete turbine. It does not provide all the details, but gives a good overview of the system.
