Our host introduces us to Marissa; no need to carry a bike lock all the time or leave a stroller unlocked outside, she’s invented an all-in-one rack and lock system powered by the sun. She hits the mall to see what other kids think. We also meet Calder and his solar powered toy car. While we follow our host as he attempts to invent cool gadgets for his own ride.
