A Reddit Community poops for purpose

13 points by Blubal3d ↗ HN
If you put your poop into an airtight container, it decomposes using a process called anaerobic digestion. This creates biogas, which can be used as an energy source. It is a big business, countries like Germany have around 10000 commercial biogas plants in operation. But also smaller tanks, sometimes smaller than an oil barrel, are often used to power off the grid and rural communities.

The composition of the organic waste along with a whole other slew of environmental factors has a massive impact on the energy generated. But because few bother to experiment, on an industrial scale current feedstock is often limited to well understood "safe" substrate such as maize or corn.

This is something a Reddit community now aims to tackle.

Anaerobic digestion of organic matter is well enough understood, that key components of the process can be described by more or less complex mathematical models. This opens up the possibility to find suitable candidates for new substrate purely through mathematical modeling. This is comparable to the automated drugs discovery process nowadays explored in the pharmaceutical community.

Using BioNet, a software modeling the anaerobic digestion process through simplified but established algorithms, a lot of the preliminary investigation is conducted. If suitable revelations about the anaerobic digestion process are found digitally, the hope is to be able to replicate this in a real biogas tank as well. Critics are doubtful of the validity of any revelations gained through this endeavor. According to the community, skepticism is warranted. But the successful applicability of anaerobic digestion models in the past raises at least the prospect that digital models are a worthwhile addition for any researcher in the field. It's similar to how computational fluid dynamics have augmented real wind tunnels in the design of a vehicle, they say.

BioNet and related software do not offer any fundamental new capabilities. But they simplify access to complicated mathematical models, that previously were only reserved to researchers in the field. Making science more open and accessible, is one of the fundamental pillars of biohacking. Because even though vague guesses exist, much of the work is still trial and error. And trial and error benefits from great participation.

I see only two Reddit posts by the author, one in r/preppers with 3 replies, one in /r/biohackers with no replies. None of the replies indicated they want to try the software.

Yeah, this sounds like someone who should have just posted the facts of their project as a 'Show HN' to see whether there was any interest. This wall of text trying to involve reddit and going into too much background of the surrounding topic area instead of just laying out what their software does... it is an odd approach and it is falling flat.

I see, at first it is air filled, and gradually as the pressure mounts with the CH4 content, you pass the lower explosive limit(at which it can function as a 'bomb') - time goes by - and you pass the higher explosive limit(at which point it can not propagate an explosion front - safe at last). Unless this was well controlled/monitored - I would tend to be averse to such a potential poop explosion. Even a small one would place a coating of poop, bacteria, degradation products over all surfaces - you as well!. How often do these poop 'pops' occur in China/India? Methane is one of the worst greenhouse gasses, over 25 times as bad as CO2 in terms of heat trapping. Do they build them with purpose built rupturable membranes or a diesel exhaust flapper valve? Or do they pipe them to a central gas storage system - like our house gas in reverse.

All retrograde steps, all roads must lead to electricity by sun/wind/geo/sea/etc as soon as possible. We need to heat/cool/drive/fly/cook/etc with electric power alone at the same time. No more coal/gas/oil/trash wasted for heat/electricity/drive/fly/cook or we will face inexorable mounting climate extremes to the point where the sea is ~~ 300 feet deeper and all former sea ports are under 300 feet of water. I suggest buy inland dwelling sites on the 300 foot aquacline so your heirs will be enriched - those that survive it??

Someone's taking shitposting too literally.
Upvoted angrily, because I should’ve come up with that myself
How come taking a shit is like taking a poop across the pond?
Not sure if you are the person in the youtube video (homeless to hollywood), but I sincerely wish you the best of luck my friend.
Is it possible to leverage a septic system to generate power?
