"Can you use a volcano to charge a LEAF?"
The answer to that question is...umm...yes and no.
While this video does reasonably well to explain the benefits of regenerative braking, it's misleading to the non-knowing public.
As we all know, you can't travel downhill both ways. If it were a one-way trip and only a one-way trip, then we suppose the logic of creating energy to boost the Nissan LEAF's battery pack applies, but that's just not reality.
Furthermore, the energy spent going up a hill/mountain is not entirely gained back coming down.
Misleading aspects aside, we still think Nissan makes it reasonably easy to understand the beneficial aspects of regenerative braking in this Nissan LEAF owner story video.
