Comment on Is WW3 more likely to accelerate or slow down anthropogenic climate change?

It has been tried many times in history since the first tanks. I wonder if modern battery tech makes it more feasible than it was 100 years ago.

This is indeed not a new concept. But the previous tank (Ambrams) was using a turbine turbo-shaft. So this is a pretty radical departure.
As for battery technology… Let’s compare LiFePo4 (not the densest, but safe, reliable, long lasting with wide operating ranges) to modern lead acid (let alone 100 year old lead acid)…
Energy Density (Weight): 120-200 Wh/kg vs 30-50 Wh/kg
Energy Density (Volume): 250-530 Wh/L vs 75-120 Wh/L
Cycle Life: 1000-3000 cycles vs 200-1000 cycles
