What was the movie/documentary that showed near the end of the movie, as a futurologic exercise, the space station crew discovering the most advanced solar power captation percentage?

I remember watching it, was amazed, and can’t remember what it was… it had an American and a Chinese aboard and the Chinese had orders to give the info to his government, and then he said on worldwide television that he hoped the government would take good care of his family, and revealed the info to the world at large instead of sneaking it only to China.

Anyone knows the name of this?

Just now reading http://www.physorg.com/news170610803.html, solar power record, 43%... and reminded me of that movie.

Thanks for any clue!
