I am working on a speculative evolution project, which takes place in a reducing atmosphere consisting mainly of methane, nitrogen gas, hydrogen gas and carbon dioxide, along with liquid ammonia as the solvent. This is a pretty reducing atmosphere, thus i dont know what will organisms consume and create energy from. I have recieved couple suggestions like:
- Using acetylene as fuel and hydrogenate it.
- Hydrazine (as fuel) from ammonia and hydrogen gas
- Diborane and Ammonia to create borazine
- People on reddit also suggested reacting hydrides and water (and also reduction to silanes) etc
I have not rejected all of them, but i would like to receive some more ideas (and speculate upon them)!
What i am looking for is a fairly rough picture of how these creatures consume and get energy to run their bodies. Photosynthetic and heterotrophic suggestions are both fine. My requirements are as follows:
Follows something like (for photosynthesis as heterotrophy would just run the reverse, with different intermediaries)
$CH4 + (NH3) + x --> y + jH2$ where () denotes optional
i.e: uses methane (and optionally, ammonia) and other stuff to create j number of Hydrogen molecules and a sugar analogue that could power the body by hydrogenating it (and release methane along with other compounds used). This sugar analogue would be needed to release fairly enough (at least 1/6th of energy released by earthlings) energy to power organisms. This sugar analogue should be able to be utilised as a solid
Thanks for reading!
