Snake Sidewinds Energy from the Sea


snake_waves.jpg How cool is this. A giant rubber tube may help pump affordable electricity from ocean waves. The snakelike design is called the Anaconda. It’s ultra-simple, cheap to manufacture and maintain, and could help deliver clean energy from the sea.

Here’s how it works. The Anaconda is closed at both ends, filled with water, and anchored below the surface. One end faces the oncoming waves. When a wave hits, the water squeezes the Anaconda, causing a bulge wave to form inside the tube. The bulge wave runs through the snake at the same time the ocean wave runs along the outside of the tube, squeezing the tube further and causing the bulge wave to grow bigger. Eventually the bulge wave triggers a turbine at the far end of the Anaconda. The power produced by the turbine is then fed to shore via a cable.

Confused? Watch the video.

The Anaconda is still only a small-scale prototype. It’s funded by the UK’s Engineering and Physical Sciences Research Council, in collaboration with the Anaconda’s inventors and with its developer, Checkmate SeaEnergy. Engineers at the University of Southampton are embarking on large-scale experiments and mathematical studies, working towards full-scale implementation.

Never underestimate the intellectual power mustering on all fronts. We may yet immunize the future against ourselves.

MORE HARD-HITTING JOURNALISM

In 2014, before Donald Trump announced his run for president, we knew we had to do something different to address the fundamental challenge facing journalism: how hard-hitting reporting that can hold the powerful accountable can survive as the bottom falls out of the news business.

Being a nonprofit, we started planning The Moment for Mother Jones, a special campaign to raise $25 million for key investments to make Mother Jones the strongest watchdog it can be. Five years later, readers have stepped up and contributed an astonishing $23 million in gifts and future pledges. This is an incredible statement from the Mother Jones community in the face of huge threats—both economic and political—against the free press.

Read more about The Moment and see what we've been able to accomplish thanks to readers' incredible generosity so far, and please join them today. Your gift will be matched dollar for dollar, up to $500,000 total, during this critical moment for journalism.
