a turbine ready for launching in the Clutha river at the Tuapeka Punt picnic 26 February 2012  

of Tuapeka turbine (linear turbine) at Tuapeka punt picnic on Clutha River New Zealand Feb 26, 2012. Tuapeka punt is operating across river using rudders and river flow to make it move sideways. Tuapeka turbine operates on similar principle with blades suspended on chains and incliined to flow to move sideways and turn wheels […]
