I think I've real that ocean craft are a 3 billion or more coatings area to prevent fouling
I think coving them with liquid metal that automatically grows a bacterial film will reduce fouling
the liquid metal has the effect of spreading across the entire surface When this liquid metal has particles
that contain bacterial spores the spores gradually release to create a friendly bacterial film on the liquid metal to preclude other growth
The bright metal surfaces with a film of bacteria glitter freshly yet the bacteria is immune to being washed off
Galinstan is liquid metal at body temperature to below freezing (link) You may have heard of woods or fields metals which are similar
One technology is to create polymer or glass fill material that beads off the liquid metal surface Then using a millifiore like approach the glass or polymer is loaded with microorganisms as well as spores then drawn to tiny size
These tiny size microorganism capsules are then blended with the body temperature liquid metal which gradually disperse the tiny microorganism carrying capsules
This creates a liquid metal which can be spread on any other metal to make an amalgam that gradually releases microorganisms The beneficial use of this is to coat the sides of ocean going craft as the metal blocks most organisms from growing while the continual gradual release of microorganism spores gives a protective film of beneficial bacteria which occupy the surface; this may also be of benefit at the surfaces of artificial physiological implants

Well, at least it has paragraph breaks. |

I think the gradual release thing might be tricky. But there are two ideas I like here. |
|
| |
1: Protective coating of bacteria. It works for lots of living things. Maybe for boats too. That is a new idea. It would be good to find some organism that had such a coating and try to replicate it. No organisms use liquid metal to sustain their protective coating and so if you were committed to the liquid metal aspect, you would have to figure out your bacterial mix by trial and error. |

2. Liquid metal. Maybe this stuf my itself could prevent fouling. It might not be a very friendly surface for things to grow on. It would have to be cheaper over time than toxic paint to be effective. The stuff looks cool. That wetting property is different from mercury. |

they did with chees? |

- I think I've read that anti-fouling was a big issue with ships - |
|

The tendency of Galinstan to eat away at aluminium might be disadvantageous, as might it's tendency to bond with many surfaces. |
|
| |
Also, the price of ~2500Euro per litre might rise if the use becomes widespread. |
|
| |
I doubt that microorganisms can survive in liquid metal (too reactive) - but maybe this would make the idea viable without them. |
|
| |
Wouldn't this wear off fairly quickly? I mean, if I understand correctly, it's just an inoculated liquid smeared onto a solid surface. Not exactly durable, if it even sticks at all. |

Why not have heating elements which can, once a month or
so, heat the hull to cook off any undesirables? |

Bunned just for being the number one Google hit for the word "autocolonize". |
