Testa

This picture is taken from inside the tunnel at the Testa River Hydroelectric Power Station Project. The most amazing piece of engg I have ever seen. This construction varies from the normal ones. Here they do not build a dam, the water doesnt need to be stored up. The flow in the river is of such a great magnitude that they dont need to build a dam. A new approach is used here, they make a tunnel in the mountain and mid way in the tunnel they fit the turbine. So the water is redirected into this and the natural normal flow of the water is sufficient to run the turbine and generate 750KW of power. And since there is no dam involved, 5 or 7 such tunnels are being constructed on the Testa river at different points. The thing is totally environment friendly!

Im lucky to have been able to see this, this is not a tourist spot! How I got in is a different story! The tunnel was so so huge. Amazing
