Building Better

Building Better with Brandon Bartneck is focused on the people, products, and companies that are creating a better tomorrow, often in the transportation and manufacturing sectors. This show was previously called the Future of Mobility podcast.

I aim to have real, human conversations to explore what these leaders and innovators are doing, why and how they’re doing it, and what we can learn from their experiences. If you care about making an impact then this show might be for you.

Topics include manufacturing, production, assembly, autonomous driving, electric vehicles, hydrogen and fuel cells, impact, leadership, and more.

Edison Manufacturing and Engineering:

Edison is your low volume contract manufacturing partner, focused on assembly of complex mobility and energy products that don’t neatly fit within traditional high-volume production methods.
