Green Sleeves are man made leaves that float in deep space; connected to space stations and orbital habits by long umbilicals. The first sleeves were translucent boxes made of a poly-hydrocarbon that filtered out dangerous radiation. The standard dimensions were 500m by 500m by 4m. They were filled with phytoplankton or algae that had to be harvested and processed. Modern sleeves are made from monomolecular carbon nets. Their surface area is several square kilometers but their depth is a few centimeters. These sleeves contain trillions of pigmented microscopic phospholipids discs that carry out photosynthesis and produce pure O2 and sugar.

I'm guessing that these are ment to harvest energy from a star, placed somewhere in the orbit of a planet, or perhaps arranged in a dyson sphere around the star itself, but this isn't made very clear. I see a lot of interesting science, I'm especially intrigued by the phospholipid discs. I wonder why manufactured cells would be more efficient than their biological analogues. Hopefully that's something we'll see expanded in the future.
I think there's a strong, innovative idea here, but right now it looks more like just that, an idea, rather than a post. Perhaps this is just too technical of a subject to encompass in a 100-word post. There's some awesome hard sci-fi here, it's just waiting to happen.

Strangely I think this was too long...

I love this place! lol

This is a cool idea. Strangely I think this was too long...
The idea of the 100 word post (as I understand it) is to give the skeleton, and let others flesh it out in their mind, or in their setting.
Great idea, I just think it could be better refined into a 100 words or better expanded into a longer post.
Also, I think you meant that instead of the in the first line.

Pretty cool sci-fi for a 100 words. Sounds like something from a book or movie.
the protaganist is being escorted around the facilities by the aging, shock-haired professor type...Professor: "And now I'd like to show you the famous Green Sleeves system. We---" Irreverant Protaganist: "Green Sleeves? Thats what handkerchiefs and tissues are for professor, hahaha--" Professor: "yes, yes. Very clever. --eye roll-- Its all in the tubing you see--" Irreverant Protaganist: "Tubing?..." Kind of like a Bond and Q encounter.
Like Roack, I'd like to know more!

Clever concept. I was thinking that these could be used to grow crops in the vacuum of space. Basically infinite farmland. But it looks like you're shooting at a source of O2 and sugar (and possibly energy). That's actually a really cool idea, but why can't we have both? Green Sleeves seem more than capable vessles to accomplish food, oxygen, and energy.

After editing, this is lot more streamlined and coherent of an idea. It's clearer what the sleeves are for and how they are used, but enough room is left for the imagination. Revoted.

This one deserves the full sub treatment, there's too much potential to cover in a mere 100 words when it comes to something so complex.
As a inspiration for a quick window dressing in a scifi setting it's good to go, but I would dearly love to see more of this, it's the start of something special.

I see these as sealed systems - you would simply add water and co2 any time you come to pickup the produce.
Radiation is less of an issue for plants - especially if you are not planning on eating them.

Vacuum only 'sucks' because the air-pressure we (and plants) need is quite high, exerting about 15 PSI. Apparently, plants may be able to survive lower pressures then us, so 15PSI may be excessive.
