  • Mostly financially. Related to hiusing. I don’t really wanna get into more details, but I’m essential stuck with my current living situation for the rest of my life, unless I’m willing to lose tens of thousands of dollars (or even more if I try to improve the place I’m currently at instead of cutting my losses and moving at an already big loss). Pressure to secure stable housing for an eventual old age made me make tough decisions that in hindsight were pretty fucking ill-advised.










  • This is indeed not a new concept. Almost all locomotives are diesel electric. Some also have batteries making them hybrids. But the previous tank (Ambrams) was using an absolute gas guzzling 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
