The idea of using solar collectors and fiber optic cables makes sense to me, as I don't think we really appreciate some of the nuances of real sunlight. It's the difference between "NPK  fertilizer" which hurts the biome, vs homemade compost tea. To make lights "more efficient", much of the range has been removed and focus is on the "essential to work" light wavelengths. Just because we don't know what goodness comes from the non-visible spectrum, doesn't mean it isn't important?

I think that DVDs or aluminum foil or whatever "found" reflective materials we might use would be great for bouncing light from the non-visible spectrum, but I know that glass (and many plastics) block at least the UVB rays needed for vitamin D production in humans. Metal bounces UVB rays better than regular mirrors due to the glass surfaces of mirrors. I'm guessing that this would be true of other non-visible spectrum lighting.

If the important thing is getting full-spectrum light into a building, then it has to somehow not have to go through glass or most plastics.  Google says good quality plastic greenhouse panels (clear polyethylene or polycarbonate) transmit the entire full light spectrum best, so to me the setup would be a sunroom attached to a building, with clear polyethylene or polycarbonate greenhouse panels. Then light that is bounced off of metal surfaces deeper into the house or other structure would be healthier for humans, critters, and plants.

The other things I like are carefully crumpled tinfoil behind glass, smooth foil with no glass, and dead CD and DVD disks. The DVDs change the scatter pattern a lot and soften the glare, and change the color.
The crumpled foil really spreads light around. Smooth foil doesn't do as well (I think it gets dirty fast) but still brightens up dark corners.

I would think that crumpled foil would work the way you are describing because it has many surfaces to reflect kind of like the DVD discs do. Now I'm thinking about some kind of a combination of aluminum can tiles with DVD discs. A work of art rather than merely functional.

I love that you are experimenting. That makes me want to experiment, too!

Now I'm thinking about what using a bunch of "tiles"made of aluminum cans  on a ceiling would do. Or the same on walls.

A kelly kettle (a.k.a. ghillie kettle) is really a kind of rocket stove, isn't it?

What the heck does "sound real" mean, anyway?

It's very well explained upthread.  Perhaps you missed it?

Never mind. It's just one more rule that I don't understand the logic for (I went to the very first post in this thread and immediately didn't get it). I often don't understand the reason for rules or the logic in how they're set up - this is obviously a me-problem and not a Permie problem. I will shut up.

Picking another 'edge case' name after your first choice is rejected often doesn't go down well. Sometimes people are lovely and have no trouble with the name policy here though.

I am an unlovely person I guess. I think one big issue is that "edge case" is too much a matter of opinion. Permie FAQ says if you need to use a fake name, it should "SOUND real".  But what if Permie decides my real name is fake simply because you're unfamiliar with what it sounds like? What the heck does "sound real" mean, anyway?

If it's my birth name and everybody in my part of the world recognizes that name because it's a common one, but the spelling is weird to English language speakers because my name is e.g. a legit click language name, and if nobody on the Permies knows what it actually sounds like, then... it's rejected as fake?  

What is the purpose of this qualification in the first place? This is a text forum. We don't need to know what people's names sound like. We just need an identifier that is easy to read, don't we?

It's one of the original brassicas to be domesticated and never had its perennial tendencies bred out. Probably older than anything currently labelled 'kale'. Every self respecting Portuguese garden has these growing just outside the back door. The lower leaves double as toilet paper.

Aha - translation issue. Thanks for the correction!

Well, THAT made me consider leaving permies, until I calmed down and went to page one of this thread, the first post, where I saw that you wrote " I want to start putting the idea out there and see if a dozen others out there wanna play with this thought experiment."

I did not read that original post before I read the fuck off comment. Now that I have read it, I understand the frustration. I just would like to remind you that I'm probably not the only person who didn't read the first post, and I assumed it was just like any other thread where it's a conversation, not a controlled thought experiment. Really, the frustration would be nonexistent if the title of this thread had been "THOUGHT EXPERIMENT: Automatic Backyard  Food Pump" and that every Paul Wheaton post in this thread reminded us what the point was, along with the request to stick with the stated purpose of the thought experiment.

With that, I will bow out of the whole thread.

It's a perennial tree cabbage, very similar to kale but 'older' genetics, which is usually kept perennial by removing the flower buds- But I've been selecting for the ability to survive seeding and have seed off one that survived for four years and seeded successfully for three of those. Generally they live for seven or so years if you take the buds off.

I don't think Galega (commonly known as goat's rue or French lilac) is a tree cabbage. It's in the legume family. Tree Kale is in the Brassica oleracea family. I think I would prefer it more than regular kale because supposedly it doesn't taste a whole lot like regular kale.
