Ideas for Nepal

hydro-power without dams

Posted by Sandeep Puri on March 15, 2008

There was an article in the Economist about free-standing turbines.
The basic idea is to harness the power of water currents without building dams. Much progress has recently been made in the design of these turbines including vertical helical turbines allowing generators (with electrical components) to reside above water, current-aligning turbines anchored on submerged platforms and turbines with newly designed integrated generators.

Possibly something to look at for Nepal’s rivers without affecting the flow of water as dams would do.
