Maybe lasers then?

What if the optics get damaged? What lasing medium are you using and what if it leaks? For long-term defense systems, I'd try to go as low-tech as possible. Every bit of technology of the past 300 years is tied to a rather large manufacturing & supply chain. If your turret has μC in it, where will you get a new one if the marauders happen to score a lucky shot?

You can reshape the question into how small could you make a microcontroller fabricator which can produce all of the electronics within itself? One square mile to one square foot - it seems likely that the best possible is within that range. How well could it be optimized?

Any one know what sort of jar that is? and/or where to buy one? Edit: its called a demijohn if anyone else was curious, used for making wine

Thanks! I was curious about that myself. They seem quite pretty and a nice size for an 'experiment' like this.

It seems like as a rough approximation your plants would need to grow at least as much biomass as you eat every day.

Yeah, so fast-growing lettuce, kale, herbs, radishes, carrots, peas, and green onions would be the order of the day.

Or a fast growing edible fungus.

Space Quorn!

If there was a plant that is not green, would it have last as long? Just wondering if the photosynthesis is only exclusive to green plants.

What other plants are there? Photosynthesis is performed in/by chlorophyll which is green, so it's hard to not be green. There is a puprle earth hypothesis and Haloarchaea, which is based on witamin A related molecule for photosythesis, but those are not classified as plants. The current theory for inception of plants is that one cell captured another chlorophyllic one and created symbiotic organism, which later evol…

A few plants are parasitic on other organisms, and have given up photosynthesis. An example is the Bird's-Nest Orchid (https://en.wikipedia.org/wiki/Neottia_nidus-avis) which is parasitic on a woodland fungus.

But these examples are unusual; the vast majority of plants get their energy the normal way, through photosynthesis using cholorophyll.

Very cool! However, I found this remark strange: > some like Bob Flowerdew (organic gardener) thinks that “It’s wonderful but not for me, thanks. I can’t see the point. I can’t smell it, I can’t eat it,”. What kind of an argument is that?

Not an argument at all, but a discussion of taste?

I think it’s quite clear. As a gardener, who values close contact and interaction with plants, he doesn’t see the point of plants that are permanently behind glass.

Are there any canonical guides to building a jar-rarium? Lots of crappy YouTube videos but nothing very thorough and complete.

Unfortunately in German but still pretty easy to get some information out of and it has DIY guides: https://ulfsoltau.wordpress.com/

How do tangible property rights differ?

If you take someones intellectual property, they still have it too. If you take someones tangible property they don't have it anymore.

If you take somebody else's opportunity to monitize their ideas, then they don't have it anymore
