Simple vs Complex, Common vs Rare

Some technologies are simple and use common materials - the digging stick being a prime example, since it can be made out of a wooden stick (common material) by a single person with basic tools (simple, doesn't need a complex society or lots of complex work done). At the other end, we have modern el...

Re: Book:"Feeding everyone no matter what"

Lo, we already know how to make sawdust into cattle feed. The downside, of course, is that cows aren't rapid breeders. I think we'd have to pre-digest cellulose and use it as fish feed, or maybe rabbit and chicken feed. Broiler chickens reach slaughter size within 6 weeks, but they take 16 weeks to...

Re: Book:"Feeding everyone no matter what"

I have that book. Cows can digest cellulose. Perhaps their stomachs would have the bacteria we need to pre-digest woodchips to make them edible by ruminants? Of course we'd have to act fast, before they all get slaughtered for their meat... the feed conversion ratio for meat is a lot worse than for ...

Caveman Chemistry

http://www.cavemanchemistry.com/ I'll have to buy this book. I don't know if it includes Sulphuric Acid, but I learned recently that there *is* a way to produce it using Gypsum and clay - roasted together they give off Sulphur Trioxide, which is dissolved in Sulphuric Acid to produce Oleum, which i...

Re: Seven Sustainable Technologies from JMGreer

If you can build a radio, surely you can built a relay? So we wouldn't need to forgo computers entirely.

Plastic books

What would be the best plastic to use? Supposedly PET doesn't degrade at all. Could a library filled with books made of such material still be usable after a few thousand years? Plastic is cheap, as well. We could easily afford to have thousands of caches all around the world. Millions, even, depend...

Try burning stuff.

If you go back really, really far. Burn enough earth and you'll figure out pottery. Burn your meat and it'll be much easier to eat. Try burning your water - you won't succeed, but it'll be much safer to drink after it's been bubbling (well, as long as it cools first). Burn certain types of earth wit...
