And will not work in the real life, because they are not paying attention to biology, just copying it without understanding the ecological processes.

Anything with tiny pores put on the sea will either be covered in life in weeks, or will need anti-fouling painting to avoid rust and life (distroying the effect), or this pores will be filled with lime and mud in no time. A ship hull that is not easily cleanable and can't be polished is creating many new problems.

I could be wrong but translating this to the real life applications seems really complicated to implement. Specially when you can just create a sealed metal box filled with multiple air cameras or a buoy.

They could put it on planes so the material floats and becomes easier to find in the case of the plane crashing into the sea. Doesn't need to work for long, only long enough for it to be found.

The main issue is that this only works on things that are tiny enough that a micro-layer of surface air can substantially affect their buoyancy. It's a cool trick, and I'm sure it has uses, but it's not going to do a thing for planes and ships. It'd be like trying to float a Buick by tying a party balloon to it.

Sadly is useless even for that. They will not found a silvery small object in a sea full of silvery small fishes and waves. If you really want to have a chance to find something in the sea you need an orange decent-sized buoy at day, or an intermitent light at night.

I don't understand why you couldn't just cover the surface with a smooth coating, trapping the air inside in a billion little bubbles.

My question with this, is that if an air bubble is formed against the surface of the material and thus the water is not touching the surface.. how does the life inside the water attach itself to the surface which it does not touch?

Marine larvae have legs with strong claws and chaetas and secrete several natural cements. They could just displace or peel the air bubble. Moreover, having tiny pores would grant a stronger grip to the hull against being washed by sea currents and cleaning hoses.

That’s assuming there’s one perfect & stable air bubble that is never broken?

If something gets into even one pore and starts displacing air, that would be enough to break equilibrium, right?

Also in a storm that air bubble will get blown out. Notice how gently they treat it in the video.
