Engine -- "The Real Stories Behind the Real People Who Make the World Work" -- is a narrative podcast, with co-hosts (and Philadelphia high school students) Lilianna Sand and Sarah Zdancewic, that tells stories from the lives of scientists who turn their greatest challenge into their most satisfying success. In this episode, "We Are One With the Sun," we meet several superstar solar car engineers who kept racing forward after their most substantial achievements literally crashed and burned. 
This is Part 2 of a two part episode.
