Kinda amazing clip from about 60+ years ago. Not only due to the fact that Jimmy Stewart (my all-time favorite actor) discusses solar power, all the way back in the 30s, but also his discussion on the sadness of letting a great idea fall by the wayside when life gets in the way.
"It takes courage. Everybody's afraid to live."
And don't get me started on playing on fears in advertising. This clip is pretty sweet(and so far ahead of its time that it borders on unreal), so check it!
