Re: 'Life After Man', 'BBC Focus', Feb 2017

Hi Bruce, RE LOCA (Loss Of Coolant Accidents) at untended nuclear plants: As a 'Doomer' I've been worried about this for years.

Re: Wax Cotton Raingear... Ponchos

Recently, I came across waxed cotton ponchos made by Dakine ( http://dakine.com ). Like, duh! Ponchos are way easier to sew up in a post cataclysmic world, and much easier to waterproof (having fewer seams). In a pinch, they can double as shelter, ground-cloth or sail.

Starting with THE KNOWLEDGE?

My thought is that a solid start for a library of concise guides in 3RBF (3 Ring Binder Format) would be to translate The Knowledge on a chapter basis. Where it seems advisable, each chapter may itself be presented as a set of guides covering related themes within the chapter. For example, the chapt...
