Primitive Technology book

Amazon link

The book just came out. It looks like it will be an essential part of any apocalypse library. One of those solar powered e-readers would do.

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...
