Via MinnPost comes this Market Watch report circa 1978. It features Jack Nicholson and a standard Chevy sedan that had been converted to run on hydrogen powered by solar energy.
I have included some related commentary from The Simpsons. I hope it helps.

The woman's voice is so strange. What is that accent? Weird Midwestern or Kansan or Canadian or something. The Simpsons thing is great.
So is the Monty Python thing in the post below.

I believe the show was Canadian. Yes, it is a strange accent.
