Shrouded at Sea: Scientists Give Ships Invisibility Cloaks

Posted March 06, 2012 3:02 PM

From Wired Top Stories:

Someone tell the U.S. Navy that rough waters might become a thing of the past. Scientists think they've figured out how to fool the stormy seas.

This is such an interesting concept, like other physical applications of metamaterials math. I am still left wondering, though, what happens to the deferred wave. There are for sure physical consequences (elsewhere) of deflecting large waves.

'Invisibility cloak' is a complete misnomer for this. My question.. will it be a weapon, then? If you don't control where that deflected wave goes, you could cause unintentional harms. If you do control it.... read my lips.

Waves move up and down. The energy of the wave can travel sideways, but an object in the water will remain at the same location.

Currents move side to side. Even waves at the beach that seem to move are really just going back and forth.

Ripples on the sea bed would impart energy on a current passing by, creating waves.

Waves have different frequencies. If the ripples are not of the same frequency, chaos will result.

On the scale they're talking about, it would require an inordinate amount of energy.

Sounds like a very complex way to stabilize a ship. I am wondering how generating these subsurface waves affects the stability of the ship (I assume the ship generates them somehow). How does this compare with old fashioned gyro stabilization?

If you had the energy to counteract the waves, then you would have enough energy to make the boat fly, this is ridiculous...
