Scratch and Bexnyl are a pair of scientists employed by Syntek Propulsion Technology Labs, one of the system's leading innovators in starship propulsion and life-support systems technologies. Scratch is a Terran engineer who specializes in space-efficient mechanical design, getting the most out of the least amount of space possible. He's a shy little fella who loves to read romantic fiction, imagining a life like that for himself, for someone to come and sweep him off his little feet, but he hasn't worked up the nerve to overcome his apprehensions and seek a relationship like that for himself. Bexnyl is a Ganymedean microbiologist studying applications for modified bacteria in the starship industry. In their spare time they like to write fanfiction about some of their favorite media franchises, although they publish these works under a Terran pseudonym, preferring anonymity, simply writing for the joy of authorship. The two have worked together for many years and have made great contributions to Solar technology.
The primary focus of Scratch & Bexnyl's work is on biofuel, finding ways to grow fuel that is sustainable, ecologically-friendly and safe to handle. Years of experimentation have lead to the production of the fuel reserve brick- compact, dormant microbe colonies that can be stimulated to produce combustible fuel for one life cycle, intended for use with existing portable generators. They look like bricks of clay wrapped in wax paper, and when they're submerged in water and mixed with an included food source the colony of bacteria will feed, convert their food source into a useful chemical and then end their short life cycle naturally, leaving behind a source of fuel that is compatible with diesel engines and shelf-safe to store or carry on long expeditions. The big theory behind their work is, fuel sources are often messy and dangerous to keep in storage, with many types either requiring special radioactive containment, having risk of ignition from exposure to flame or being prone to chemical breakdown over time. Scratch & Bexynl attempt to solve these problems by engineering ways of storing organic bacterial colonies that themselves produce new fuels that are ready for use when the need arises, that can be safely carried and that maintain their usefulness over long periods of time. This technology has useful small-scale applications, but the team at Syntek has bigger ambitions than just keeping electric generators running.
Stranded starships have been a problem people have faced since the advent of the space age, and every world has run into this same limitation. Starship technology has seen tremendous fuel efficiency advancements over the centuries, but that fuel isn't infinite, and many a starfarer have underestimated the distance between one world and another. "I've got enough to make it", they'll think, and they might have been right when they first charted their course, but the rotation of the planets can alter those distances and when they're out in the middle of nowhere, well! It turns out you didn't have enough fuel to make it after all. Emergency satellite networks allow stranded travelers to put out distress calls from the middle of nowhere, and a tow service will come to rescue them and their ship, but there aren't always happy endings to these stories. If you just had a little more fuel it would have made all the difference- this is where Scratch & Bexnyl feel like they can provide a solution.
By adapting their small-scale emergency biofuel technologies to the needs of the modern starship, Scratch & Bexnyl believe they can retrofit emergency power sources to existing starships of all makes, providing shelf-stable opportunities for crew to recover from catastrophic loss of power or simply maintain life support and emergency communications systems until help arrives. In terms of engine propellants, there are a few limitations they're working to overcome:
- Starship fuel is a bit more complicated than diesel fuel. Starship fuel undergoes a conversion from a liquid state to a gaseous state before exposure to an engine core ionizes the gaseous fuel and creates propulsion. Bexnyl has been working on developing organic alternatives to the liquid form of this fuel, that their bacteria colonies might be made to produce it.
- Starship fuel storage and conversion systems are designed to be contained and isolated from habitable quarters on a starship, as both the fuel and the radioactive engine cores are generally unpleasant for starfarers to be around. In order for an emergency biofuel source to be useful it would have to be accessible to a ship's crew, which means connecting the fuel systems to the interior of the ship in a way that is safe for crew to open up and access. Scratch has been devising multi-chambered solutions to allow the emergency fuel kettles to be connected to the main fuel system without endangering the habitable space.
- Emergency microbial fuel colonies need to be prepared as shelf-stable bricks that can be neglected until they're needed, and the food-source reagent the microbial colony would eat to convert into biofuel needs to be stable and safe to handle as well. This is the case for their current diesel fuel colonies, but the needs of starship biofuel might make this point challenging to overcome.
- The system needs to be simple enough that it can be retrofitted to a wide range of starships. Most interplanetary ships have converted to the current standard starship fuel source, but ships from different worlds are likely to have different architectural layouts, and so a Syntek emergency biofuel kettle needs to be readily-fitted to a Mercurian musclecruiser as well as a Ganymedean cargo hauler or a Neptunian passenger shuttle. Making the system overly-complicated creates barriers for adoption.
The idea of starship biofuel is an exciting one, and emergency fuel kettles are just the first stage of a grander vision of the future. If Scratch & Bexnyl's microbe colonies can be self-sustaining, if they can keep the microbes from dying out after a generation, then biofuel colonies can provide fuel in extremely remote locations, allowing for fuel depots that don't require external restocking or, beyond that, self-sustaining fuel reserve colonies within starships themselves! You'd still need to feed the colonies something to convert into fuel, but it could be less expensive and less dangerous to handle than current liquid starship fuels. The Sol system has changed their primary fuel sources once, they can change it again. We can strive to be cleaner and more self-sustaining in supplying our energy needs- starship biofuel doesn't need to remain a work of fiction! From humble sources, we can bring about a better tomorrow.
