It was not all that long ago that propane would have been considered very green. But now with globull warming, the story has changed. As for those batteries, it isn’t all that green an undertaking to make them.
Yup. Propane does not have a mercury or other residue those batteries have.
Sad for the athletes that these green icers were junk. The Zambonis are so cool. You would have though the freaking Canadians would know ice from their obsession with hockey. Incredible.
