Building Design, Chetwood Associates’ sail-like ‘wind dam’ lands on Lake Lagoda:
“The dam, which would be located over a gorge at Lake Lagoda in north-west Russia, includes a cup-shaped spinnaker sail, believed to be the first of its kind, which will generate renewable energy by funnelling the wind through an attached turbine.
The spinnaker shape is similar to the mainsail of a yacht, and is thought to be particularly effective in capturing wind.”
