By the way, feel free to ask me more about this stuff, if you're curious. I'm always happy to share knowledge.
@InvaderXan I would love to know more! What processes are you looking at? How is the work progressing? How do you see the technology being applied? Got any papers you're able to share? How long have you been at it?
This would probably be super awesome for space stations, actual plants are tricky in microgravity and the carbon scrubbers they have now need new filters shipping up every so often...
* The basic process involves charge separation and flow of electrons, a lot like in photosynthesis. Plants use this to split water. I'm hoping to use it to directly split carbon dioxide, if that's even possible.
* It's progressing steadily, but slower than I'd like. There are a lot of people working on carbon sequestration. Finding something that works well is easier said than done. Being a theorist, I hope to help narrow things down.
* The ultimate goal is to apply it on a large scale. Pulling CO2 from the air gives a source of hydrocarbons which doesn't use fossil sources. This could either be used as carbon-neutral fuel (short term) or be used for permanent removal of CO2 from the atmosphere (longer term).
* Here's a summary from a 2017 conference, which should be open source: https://pubs.rsc.org/en/content/articlelanding/2017/fd/c7fd00133a#!divAbstract
* Not long. A few months. I hope I can get more funding for next year...
And space stations... I don't see why this kind of thing can't work together with plants. NASA have been studying how to grow things in orbit for decades, after all. The only difficulty is growing enough of them, so an artificial system could help out where required.
@InvaderXan Improved RuBisCo? I don't know if that is the same thing but was thinking of it randomly yesterday
@InvaderXan Really cool. I tried to switch careers into plant bio a while back but life had other plans. I had dreams of working with heirloom crops to breed varieties specifically suited for the needs of organic agriculture.
Life often has other plans, sadly. Pity too, that sounds like an interesting thing to work on!
