A snake in the water: It harnesses wave power for electricity

Snake power: It looks like an ordinary tube, but this device is a small version of the Anaconda, a snake-like tube that turns ocean wave power into electricity.

Indiana Jones may hate snakes, but those looking for clean, renewable energy sources are loving the chances that a “snake” may be able to generate electricity from ocean waves.

It’s not a real snake, but an enormous rubber snake called the Anaconda. Stretching more than 600 feet long, the Anaconda produces energy as it is squeezed by the passing waves of ocean water that it is submerged in. The process is very similar to what happens with a windsock fluttering in the wind.

The Anaconda is filled with seawater and is sealed at both ends. The trailing end of the snake has turbines. As the ocean waves ripple by the Anaconda, the water inside is squeezed and pushed in bulges that move toward the turbines. When the bulges get there, their energy turns the turbines.

The idea is being developed by the British firm Atkins Global. This is all still in the testing stages, but if the research pans out, the Anacondas would be submerged in ocean waters at depths of 120 to 300 feet.

So far, however, researchers are testing their theory on smaller snakes in a wave tank. Seawater testing could begin next year and if everything is successful, the technology could go online commercially in five years. Estimates figure one full-sized Anaconda could generate 1 megawatt of electricity, about the same amount of power for 2,000 homes.
