Hand-Crank Vending Machine Perfect for Disasters, Workouts
In the aftermath of Japan's earthquake and tsunami, Sanden has created a vending machine that works without electricity.
This hand-cranked machine takes some 70 turns before it has enough power to do anything, but in one charge it can drop six to seven bottles at a time.
In the past, Coca-Cola has created a solar-paneled vending machine, but the hand-crank might make more sense in dense, often dark cities. Plus, it would be a great deterrent for things like the cupcake ATM.
