WIRED prototypes four world-changing product ideas from Bill Gates

WIRED invited Bill Gates to be the guest editor of their latest issue, and now they’ve brought four of his recent ideas for global good to life through a colorful set of prototypes by top design firms.

One product, dubbed the Juice Box, is a portable device that can transform nearly any power source into a battery charge, bringing usable power to the billion-plus people who live off the grid globally.
