This emergency backpack filters water and generates electricity for small devices when disaster strikes

Worn as either a backpack or a chestpack, FFD contains a water filtration system operated with a hand held pump. A tube with a float is placed in a water source, and a lever on the outside of the pack is pumped to move water through an activated carbon filter. Water is stored in external bottles and filled via a port on the outside of the pack. The pump action of the lever generates electricity with the help of a dynamo, which is stored in a lithium ion battery and used to charge small devices, like phones or radios, via a USB port.
