A team of engineers are testing turbines in Lake Washington that are designed to turn tides into usable energy.
Every day the tide rolls in and out of Puget Sound, and engineers at the University of Washington would like to harvest some of that energy for public use. Tides are a renewable energy source that is more predictable than wind or sun, but the technology has not accelerated at the same pace as other renewables. Tests of cross-flow turbines on Lake Washington are a step forward in the development of this new source of power.
