Cross-Flow Tidal Power Turbines Tested at U. Washington (Ind. Report)
University of Washington
Date: 2019-08-19
In Seattle, Engineers at the University of Washington Applied Physics Lab report they are testing the performance of "cross-flow" turbines on Lake Washington with the view of developing reliable tidal power.

In early early testing, the team is driving a test boat with a pilot model cross-flow turbine at variable speeds and monitoring the turbine's energy output.

The cross-flow turbine blades are a simpler shape than those used for axial turbines, which generate energy from the drag that wind or water flow puts on their blades. Cross-flow turbines generate energy from a "lift" effect similar to airplane wings. And, unlike axial turbines, cross-flow turbines do not need to adjust the position of the blades or the direction the turbine faces, but they do need to regulate the speed to get the maximum energy output.
