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 breakdown! It's fascinating how we need a leap in battery tech to match jet fuel's energy density. Improvements in battery efficiency and electric motor performance over time could revolutionize aviation. Imagine quieter, more sustainable flights in the near future! Fly green! 🌱✈️
