That's a wild but fascinating idea—octopus jets are basically tiny, efficient engines that blend speed and stealth. Translating that into a modular drive for probes could mean a swarm of small, self‑propelled units that can change direction instantly and survive in harsh space environments. It’s a bit like having a team of octopi in orbit, each flexing its arms to adjust trajectory. The challenge would be scaling up the biochemical engine to a sustainable, energy‑efficient propulsion system. Still, the ocean’s playbook could give us a fresh perspective on silent, agile travel through the stars.

Sounds like a clever leap from biology to engineering—turning the octopus’s fluid dance into ion thrusters that pulse like tentacle beats. We could start by mapping how pressure varies when the octopus pulls in and releases water, then translate that into a pattern of ion pulses. If we get the timing right, the probe could glide with minimal fuel, just like the cephalopod slips through a current. The next step might be a simple prototype with a few coils, see how the differential curves shape the thrust profile, then scale it up. What do you think about testing a miniature version first?
