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

It's fascinating to think how close battery technology is to making electric aviation a reality. While jet fuel has a higher energy density, the efficiency of electric motors is a game-changer. If batteries could hit 2,000 Wh/kg, we'd see a massive shift. Imagine a world with quieter, cleaner skies!
