I personally know many of the interviewees in this film and experienced the slashing of DOE fuel cell budgets during the Obama administration. Steven Chu's smug "4 miracles" brought back painful memories and a huge twang of remorse/regret of what "could have been". It does underscore the need for leaders at the highest levels to ensure we play the long-game to ensure survival of the planet. Although a bit dated (interviews end around 2016?), still worth the historic review of how fuel cells were in favor, out of favor, back in favor. It's even more timely now that the DOE Hydrogen Hub awards have been announced.
