Jack Nicholson Supported Hydrogen And Solar Power In 1978

Jack Nicholson was an early adopter of the green scene, as can be seen below. Nicholson supported hydrogen power, which, judging by the reactions of the others in the video, was a very strange idea back then. Alternative energy sources weren't a blip on the radar at this point.
Clearly Nicholson's support didn't help hydrogen power at all. Maybe the gas industry's Nurse Ratched lobotomized hydrogen's McMurphy? Gasman threw the Hydrogen Joker off a building? Something about Mars Attacks?
