How do you prevent insurgents from shooting down choppers? How do you keep a cast from itching? How do you reinvent the brick? You sketch. And then you work: nights, weekends-for years, if you have to. You blow all your money, then beg for more. You build prototypes, and when they fail, you build more. Why? Because inventing is about solving problems, and not stopping until your solution becomes real.
Here, we present the 10 winners of the 2007 PopSci Invention Awards. Each is a stunning example of the spirity of ingenuity. You'll also find tips from the world's most successful inventors on how to get your own ideas out there.
