This episode of Now What is, on one level, a story about All Power Labs. APL is a group of genius misfits - Burning Man artists, brilliant engineers, and welders with a rebellious streak - and to properly understand them, a bit of backstory is required. Originally, they ran an illegal art compound on the outskirts of Berkeley, CA. The city didn't like that much and cut their power in an effort to evict them. Rather than cave in and move out, they built their own power generators based on old World War II technology.
