That's a great documentary for data nerds and quant-types -- it's basically a bloomberg interview with the market analysts and the manufacturing plant operators talking about why the trends are exciting and how the finance markets are starting to see real return in this field. Stuff like experience curves (https://en.wikipedia.org/wiki/Experience_curve_effects) and cost parity.

My favorite was the guy who noted that in resource-based industries, things get more expensive the more you use; solar and wind are manufacturing-based industries where the more you use, the less expensive things get because you get better at making it.
