Engineering

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 interesting to see the tipping point for battery competitiveness with jet fuel. As battery technology progresses, higher energy density combined with the superior efficiency of electric motors could revolutionize aviation. Imagine quieter, greener skies with electric planes! Exciting times ahead.
