Artificial photosynthesis

[SAZAR]

I've been trying to google-out some things about this issue, but - nevertheless I ask here because this issue seems very interesting:

Is there a way to PURELY ELECTRONICALY (i.e. it doesn't use any NON-REUSABLE chemicals in process that you must replace in order for apparature to function) separate oxygen from carbon-dioxide so you could strap a mask (with such mechanism attached) on yourself, and breath air practicaly indefinitely (as long as there is electric power supply (solar panels on suit or nuclear power generator for air inside rooms at all times)) for use in space, under water, non-brathable atmosphere (...such as... ...well... Mars for example...) etc.

Is it possible (I mean - in ways chemistry works) to make such apparature at all?!...

(...it definitely sounds like an ultimate solution)

--------------
Also it could use water vapour from breath to recombine it with carbon and syntesize sugar. (basicaly - a complete emulation of processes which plants use - that's what I'm talking about...)

Yes, it is possible to separate oxygen from carbon dioxide using purely electronic means. This can be done through a process called electrolysis. In this process, a current is passed through a solution of water and salt. The oxygen is then released at the anode, while the carbon dioxide is released at the cathode. The oxygen can then be collected, while the carbon dioxide can be vented out. This method is used in many industrial applications and is a viable option for separating oxygen from carbon dioxide in a space or underwater environment.

Artificial photosynthesis is a field of research that aims to replicate the process of natural photosynthesis, where plants use sunlight to convert carbon dioxide and water into oxygen and energy in the form of sugar. This is a highly complex process that involves multiple steps and requires the use of various chemicals and enzymes.

While there has been progress in developing technologies that can mimic photosynthesis, it is currently not possible to purely and solely use electricity to separate oxygen from carbon dioxide. This is because the process of photosynthesis involves more than just the use of electricity – it also requires the presence of specific enzymes and chemicals to catalyze the reactions.

However, there are ongoing efforts to create artificial photosynthesis systems that can use renewable energy sources such as solar power to produce oxygen and energy. These systems would not rely on non-reusable chemicals and instead use renewable resources to power the process.

In terms of using this technology for breathing in space or other non-breathable environments, it is possible to create a closed system that recycles and purifies air using artificial photosynthesis. This would involve using the byproduct of photosynthesis, oxygen, for breathing and then using the carbon dioxide produced by breathing to fuel the photosynthesis process. This would essentially mimic the natural process of plants.

Overall, while the concept of purely electronic artificial photosynthesis is not yet possible, there are ongoing research and developments in this field that could potentially lead to a more sustainable and renewable way of producing oxygen and energy.
