Yasch22, any thoughts on the matter of battery fires;
in particular, how they may affect adoption of all-electric propulsion?
Here's an article: https://www.bloomberg.com/news/articles/2021-09-24/battery-fires-haunt-the-electric-car-and-clean-power-revolution
My (limited) thinking on the matter would relegate "big battery" power mostly for stationary applications such as storing solar power for household use, rather than 100% electric vehicles.
We seem to hear less and less about hybrid vehicles, which not long ago seemed to be contenders.
