If you want to learn a bunch of amazing information of the lives of fungi and the diversity of things they are good at doing check out the book Entangled Life by Merlin Sheldrake. With what you are asking of fungi it sounds like it might need to be a plant-fungi symbiotic organism to extract nutrients from waste matter but also energy-dense chemicals like ...

Marmite ... is a prototype of a fungi-based diet. It is a concentrated yeast product, and apparently is still useful for making moonshine. (If only under unusual circumstances - Australia's ongoing experiment in Prohibition also led to the invention of non-intoxicating gasoline, and they are not done yet!) I see 39 g protein and 29 g carbohydrate per 100 ...

Technically... Fungi are kind of bottom-feeders. Currently, mushrooms are low in carbohydrates, low in fats, and low in protein (except in a Dr. Who episode I watched once). The fungi would need to be breaking down high-calorie materials (not generic wastes) in order to have enough energy to make all these things, even with genetic engineering. They are high ...

A lot of folks have raised concerns about food going bad in metal pipes, but do we any real-life example of a system where food is stored in metal tubes and doesn't go bad? Yes! Canned Food You can imagine the pipeline being a 1 huge can. You would need to add the following mechanisms to make this work - From the factory, sausage is is put in a preservative ...

I'd actually suggest bigger pipes and screws. There's certain kinda of pumps that do better for this - If you need a constant flow of mush between 2 points, a positive displacement pump works, and you can use a screw system to tap off materials. It might also be useful to consider if your food mush can be self lubricating -which would ease movement, either ...

The end-goal is to get a continuous sausage out of the machine. First a caveat that people have already mentioned: if the food remains in the tubes because people aren't continuously using sausage it shouldn't go bad. So I would assume that everything is 100% sterilized and cleanly passed through the sterile tubing system. For example the food is irradiated ...

Pigging Your pipeline needs to be clean, and odds are, you want to keep your food items separate. After all, you might have trouble returning a transmix of onions, curry, chocolate and sausage back to the refinery for reprocessing. So you need to send pigs through the pipeline. No, not genetically engineered 1-inch "imperforate" pigs that can ...

An oil pipeline. Guess what goes bad if it's left overnight in a pipe at ambient temperature? Food with water in it. Guess what wouldn't go bad? Oil. I would propose a three-step system: At source, the sausage ingredients (stored dry) are ground into a powder and mixed into a (comestible) carrier oil to make a sort of liquid pemmican. The pipes will carry ...

This is a semi-frame-challenge. I don't believe your premise, as it currently stands, is feasible. However, one way you could get close would be to forget the "continuous ooze of food" and instead create a pneumatic grocery delivery service. With sufficient automation, users should be able to order any food the system can deliver and have it in ...

Allow me to offer up a question of my own from the dim & dusty past by way of answer. Allow me to present to you [flourishes hand theatrically] the Ancient Roman Pneumatic tube Postal Service. In short, a pneumatic tube message & small parcel delivery service of the type occasionally found (albeit to smaller scale) in old department stores at the ...
