However, in some experiments this algae was spread over 8 m2. So, my question is - would it (theoretically) be possible to build a suit that would use algae as regenerative life support? … Is it possible to carry the algae in a wide enough spread layout to rely on natural sunlight, for example, on Mars? …

Recently, I saw a video on Cody'sLab, where an “algae panel” was constructed. This is set up like a solar panel and uses algae to convert light and air into food and oxygen. … You can use any algae species you want, however it must of course be edible. …

I believe that the requirements for a single persons $\require{mhchem}\ce{O2}$/$\ce{CO2}$ balance run somewhere in the region of $8m^2$ of algae, which would seem to be possible in a single $\approx 1m … 2) Also can't find data on how long this algae would take to 'grow' to a stage where it could be harvested? As in what would the calories per month be from such a setup? …

I am currently researching the idea of growing spirulina algae on Mars for as a renewable source of oxygen, food and material. …

A carbon dioxide enriched nitrogen or helium medium would be needed to be processed by the algae and then by humans. … Would the waste from one human and carbon dioxide from Mars sustain the algae to produce enough oxygen for 1 or more human to breath? …

How long can nutrients found in Mars along with an algae diet sustain human life? …

If we provide adequate water supply will it be possible to grow plants/seeds/moss/algae (from Earth) on Mars? How different are Mars soil from Earth's soil? …

Although, there might be some algae or similar that would tolerate the intermittent light. …

The August 2017 BBC News Science in Action podcast The Algae that Changed the Earth includes other topics, including the following: In August and September 1977, Nasa's probes Voyager 2 and Voyager 1 …

While this article suggests some lichens and cyanobacteria (the organism previosly known as blue green algae) are tough enough to handle Mars. …

By the way, don't mind the "micro-bacterial algae" I'm working on it at the moment. …

CO2 could be converted back into O2 using algae bioreactors. There is a demonstration unit on the ISS. …

Algae are known to efficiently process light and CO2 into food for themselves and oxygen. By bubbling the CO2 through the water, the algae would be able to absorb it and produce oxygen. … Links: Algae absorbing gamma rays, Feasibility of growing algae in space …

Algae does not make for good human food. Algae requires a lot more water to productively grow than other plants. … suited for these purposes than algae. …

Light is toxic to the photosynthetic enzymes in algae. … The algae themselves attenuate light so either algae density needs to be low (lots of medium) or LEDs must be close together (lots of LEDs). Algae are not very efficient at converting light to O2. …
