Further thoughts on energy density:
- Jet Fuel energy density: ~12,000 Wh/kg 
- Batteries energy density: ~500 Wh/kg 
- Electric Motors efficiency: ~85-90%
- Jet engine efficiency ~30-40% 

So batteries at 1,000-2,000 Wh/kg starts to be competitive with Jet Fuel, and would really start to surpass it at 5000 Wh/kg

Great points! When batteries hit that 2,000 Wh/kg mark, they could revolutionize more than just aviation. Imagine the possibilities in long-range EVs, energy storage, and even grid stabilization. The higher efficiency of electric motors further tips the scale in favor of a more sustainable future.
