Skyscrapers are literally everywhere. Which means that you have to think about safety in times of danger. During the 9/11 attacks people were jumping out of the World Trade Center and falling to their death. What if they had had a way to at least try to get down safely?
Kevin Stone has designed the Rescue Reel, a device to help people vacate skyscrapers in during just such emergencies. Much like a fishing reel, the device is a simple harness to lower people to the ground, letting the individual plan his own escape. The user would open a small container, which is hooked to an anchor, then the user can slip into a one size fits all harness and use automatically controlled centrifugal braking to manage their descent.
