Appeal is a new battery charger concept that requires no energy source beyond the simple activity of swinging a rope. The concept charges batteries by tapping the centrifugal force created from swinging the charger around repeatedly in a motion similar to that of a lasso. I'm sure hikers will see this charger as a great way to keep camera batteries charged on long hikes, only to accidently swing the charger into their head, sending their batteries flying into the woods and leaving them as unconscious prey for foraging mountain lions. In the end, I guess that's the secret goal of most electronics, finally putting an end to the terrible scourge of hikers once and for all.
