Got to go? Scientists have figured out how to recharge devices using human pee. A giant "Game of Thrones" dragon skull washes up on a U.K. beach. And we congratulate the AeroVelo human-powered helicopter for winning a high-flying honor.
On this week's Crave, scientists recharge devices with pee power, air guitar gets a boost with LEDs, and a small Colorado town wants to issue "drone hunting" licenses. Yup.
For the first time since its introduction in 1980, the $250,000 Sikorsky Prize for a human-powered helicopter flight has actually been awarded.
