I actually rediscovered an old story I wrote five years ago and there was this supposedly synthetic material that can float, be programmed to be directed where to be delivered and can carry luggage (I'm assuming ~100kg) and can withstand firepower from the tumultuous society that's currently in civil unrest against a tyrant.

I'm wondering if anyone knows if something similar in reality could be incorporated even theoretically.

  • $\begingroup$ Can you give us more information? I understand generally what you are asking for, but I need some details. For example, what kind of firepower do the tyrant's troops have at their disposal? $\endgroup$ – Marvin the Paranoid Android Jan 22 at 23:40

    $\begingroup$ So... Armoured Amazon delivery drones? In practice, almost any material can float if shaped correctly - modern ships are made of materials that would sink if not shaped like boats and any object can be programmed by the simple addition of a computer. Unless you're talking about the kind of liquid metal terminators that are popular in the movies that are intelligent and can change shape it would be great to get more clarity about what you're asking for here. $\endgroup$ – Tim B II Jan 22 at 23:45
  • $\begingroup$ classic gunfire, deadly light gun rays it's seethrough as well.and no doesn't change shape, they're honestly kind of like spherical bubbles. except not as weak as a bubble $\endgroup$ – CheckersBoard Jan 22 at 23:47
  • $\begingroup$ Wood fits all those criteria, especially harder woods when you turn it into a ship. $\endgroup$ – John Jan 23 at 1:22
  • $\begingroup$ Concrete works as well. Concrete floats when formed properly to have large air cavities within it. $\endgroup$ – Cort Ammon Jan 23 at 5:40

Aluminium OxyNitride

So, if you're a Star Trek fan, then you'll have heard of transparent aluminum and as it turns out, it's now a thing. Aluminium Oxynitride is also called transparent aluminum and is marketed under the name ALON as well. It's quite bulletproof, is lighter than most bulletproof products, and if it could be shaped into an empty sphere like you describe in your comments, would pretty much fit the brief of all but the programmability (and perhaps the maneuvering to the assigned location). Fortunately, because it doesn't have to change shape we can add to the inside of the sphere a very simple solution to this - a computer. Hell, even just a NavMan if all you need it to do is get somewhere.

Getting it to be able to move around as well is a bit tricker, but you could put external 'fans' or turbines on it to get it to move in a desired direction, especially when alfoat, meaning that you pretty much have all you need, and a little more. Because it's (mostly) transparent, you can even tell at a glance whether the bubble is taken or not. Of course that works both ways as it means that pirates can pick and choose what bubbles to go after, but getting into them is going to be harder because... Well, transparent aluminium.

  • $\begingroup$ Closest thing to what I'm looking for!! Thank you! I'll refer to this material more (and wow I should really get around to watching Star Trek one day haha) $\endgroup$ – CheckersBoard Jan 24 at 2:09

You're talking about the U.S.S. Constitution

The Constitution floats, can carry 100kg of cargo (or more!) with ease, and (with favorable winds) can sail where directed. Her hull is 22" thick and consists of three layers of oak (white oak, live oak, white oak), and she is nicknamed "Old Ironsides" because cannonballs were observed literally bouncing off her sides during a battle with HMS Guerriere.

If this is not the accepted answer, the question may need more clarification.

Nanites

Theoretically nanites can form any shape object could easily form a foam or a boat as to float as well as move under it's own power.

It could also form shapes to absorb gunfire and make shields or armour like Iron Man's and Black Panther's armour in Marvel comics
