We've compiled the most promising and innovative solutions we could find to common survival problems. Some are just concepts and others are already available. We might not trust our lives with all of these designs, but at least they're a step in the right direction.

The Cocoon is a short-term shelter made of durable insulating material that hangs off a tree (or any stable structure). In theory, getting the user off the ground seems safer, but it's still pretty vulnerable. Sure, you wouldn't be prey to wild animals, but the wind could swing you against the holding structure like a piñata and making a hasty exit from the cocoon seems unlikely.
