I'll need to dig it up, but somewhere out there on the Intarwebs, someone has debunked the feasibility of the Cocoon.
The earthquake bed, I dunno. Something seems silly about it.
Something similar to the Bedu might be a good idea for local disaster relief groups, particularly in the Southeast US.
The urban skiff looks fun, but it might just be cheaper and consume less space if you kept a folbot or collapsible frame canoe in your closet.
The Lifesaver bottle is not worth the money. Hand pumped ceramic filters, battery operated and solar powered UV purifiers, and iodine tablets are all more efficient (and cost effective per gallon) despite the claims.
You can do a DIY solar oven which would be much more effective than the BCK.
The Firun looks like it'd be much better than trying to rig a travois in the back country.
The survival radio and personal beacon are good ideas, and there are plenty out there.
The water shelter and wind turbine seem like good ideas. There are also a few solar powered ice melters that would be cheaper than the wind turbine, but I don't know about the efficiency.
That Campa makes me tingly in my campin geek no no parts.
(TEOTWAWKI/Zombie contingency plan? I have no idea what you mean...oh, I love what you've done with your ceiling!)
