> According to ESA, Mars' atmosphere is composed of 95.32% carbon dioxide, 2.7% nitrogen, 1.6% argon and 0.13% oxygen. The atmospheric pressure at the surface is 6.35 mbar which is over 100 times less Earth's. Humans therefore cannot breathe Martian air.
> Now, in a study published this week in the Proceedings of the National Academy of Sciences, the NASA Curiosity rover team reports detecting nitrates on Mars. ; nitric oxides
> In Solein's case, the bacteria oxidise hydrogen – a process involving the removal of electrons from the hydrogen molecules. This reaction releases energy, which the bacteria use to fix carbon dioxide, transforming it into organic compounds, including proteins.
> [...] Rondinone [@ORNL] and his colleagues had put together a catalyst using carbon, copper, and nitrogen, by embedding copper nanoparticles into nitrogen-laced carbon spikes measuring just 50-80 nanometres tall. (1 nanometre = one-millionth of a millimetre.)
> When they applied an electric current of just 1.2 volts, the catalyst converted a solution of CO2 dissolved in water into ethanol, with a yield of 63 percent.
Algae produce amino acids and proteins.
Algae also use CO2 and Hydrogen to produce Omega-3 PUFAs, which are precursors to endocannabinoids.
FWIU Hydrogen Peroxide can flush aquarium tanks and Kratky systems. From watching YouTube, IDK about pool noodle polyethylene foam in the sun (solar radiation) instead of rockwool though
