This Musk — Elon's brother — looks to revolutionize urban farming

In sunny California, Elon Musk is upending America's auto and space industries. And here, in a cold, gritty section of Brooklyn, his brother Kimbal has embarked on a project that's just as significant in its own way: Trying to reboot the food system. The younger Musk is the co-founder of Square Roots, an urban farming incubator with the goal of teaching young people how to farm in cities while preaching the importance of locally sourced, non-processed food.
