Solar Power Cart
Mouna Andraos has been fascinated by street vendors since her childhood in Lebanon. She’s an artist and designer with no engineering background, but she has created a working portable street generator that uses a crank and a solar cell to charge cell phones and laptops. Ada Lee Halofsky hit the New York City streets with Andraos to see Power Cart in action. (Originally aired: April 18, 2008)
