Water Invisibility Barrier Protects Against Tsunamis
Posted by Gizmodo US Edition at 1:35 PM on October 1, 2008
Research into invisibility cloaks, which work by bending light around 2D objects, could end up protecting offshore rigs and vulnerable coastlines from water. Scientists at the Fresnel Institute in Marseille, France said that established cloaking principles can be applied to ocean waves, and built a 10cm model to show how carefully placed concentric pillars make objects in the centre "invisible" to the sea.
Waves pass along the radial corridors, interacting with the pillars and producing forces that pull the water away from the innermost ring. The water is then pushed out of the cloaking area as if it had not encountered anything at all. The circular formation could be used to protect anything from oil rigs to islands, though very few islands can probably afford the amount of pillars needed to make this effect work.

@thefutureisnow: Metal frame and living coral would get my vote, but I think concrete will be a lot more likely. I can't wait for the environmentalists to scream bloody murder if this ever sees the light of day.

Or for about a quarter the materials you could raise your gizmo 150 feet out of the water.

@tkohrs2002: they say the world pool current would be so strong it would pull it around the whole thing and fling it out the other side... I'll believe it when i see it.

I can just picture it. Tsunami warning, sirens wailing, lights flashing, and columns of pillars rise slowly from the seabed. Very anime-ish.

My guess is aluminum. But it's not the material that matters, it's the gaps between the pillars

@LastAndLeast:
But it probably works better than a wall. A wall would have to absorb all the energy from a wave, this looks like it would just deflect the energy of the wave, and hardly absorb any of the wave.

True that. At least debai actually spends it's money on useful things that are hell of a lot more productive then this gay arse war we're in.
Seriously imagine if we took that war money and rebuilt some infrastructure in America. Imagine what cool building we could have here. We're so 20th century.

My guess is it has to do with interference patterns or something of the such. In any case the science that applies to one type of wave applies to another. It's one of the reason's the wave is so interesting.

Neat idea, but I can't help but imagine that a tsunami will likely take out the pillars as well, and send a hundred, giant pillars raining down into the middle section. :)

Whoever said a wall would work is right...love the idea but problem is that if one of those inner pillars goes down in the process, then everything inside may be more f'd than would be without the pillars in the first place.

@tkohrs2002: It's an evolution of the already-existant slosh plates. The pillars may not even need to be above the water's surface: as a wave passes over/through the array its energy gets gently spread around so its not so concentrated in one point.

Ocean waves are a natural process that help to circulate nutrients and waste throughout. Wouldn't this basically create a giant dead zone around the area?

Posted 10:38 PM 1/10/08
The_Gas_Man: invisibility in the sense that the ocean waves never hit the island, but they also don't get reflected back out (as they would with a circular wall). Someone looking at just the waves (as opposed to a light image) wouldn't see the island at all. It would be invisible.

It looks like the pillars would break up the oncoming waves. A wall would simply take a beating. I remember PopScience article a long time ago using underwater baffles to dampen the waves.
I'm sure they could also use these pillars to harness energy of the waves. It could help with the cost.

Posted 12:56 AM 2/10/08
Geniuses; I'm pretty sure the point of this is that it would sit on the ocean floor, and the drag caused by the pillars dampens immense waves to near nothingness. If the pillars were meant to extend all the way to the surface, a single ring would be more cost effective. Just like Planet Druidia.

If they can build a pillar to withstand the force of a Tsunami, why don't they just build a platform that's as strong as the pillar itself? Better yet, why not have a platform that rises and lowers like Stromberg's in "the Spy Who Loved Me?"

@Guapo: It doesn't "withstand" the force of the Tsunami, it re-directs it. That's why a wall is a horrible idea. It just gets beat on and beat on and beat on. This idea dissipates the force of the Tsunami around the target.

@Optimus-Prime: For a wedge shaped wall, you need to predict where the wave is coming from. If it's a coast line, then a wedge is fine, but for something in open water exposed to waves from all directions, this approach seems better.
