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.

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
