In an age where gas-powered vehicles account for nearly half of greenhouse gas emissions in the transportation sector, electric vehicles are a way to help slow global warming.

In this episode, Wally Rippel remembers gazing out his classroom window at the air pollution hanging over LA one smoggy day and how that led to building what would become GM’s infamous EV1. Then Wim Ouboter recalls how his homemade push scooter started a chain of events that inspired him to build a miniature electric bubble car named the Microlino.
