The Energy Density Wall, Watt-Hours Per Kilogram, and the One Number Electric Aviation Has to Beat Before Any of It Works
Electric aviation lives or dies on one number: watt-hours per kilogram. Here's the energy wall it has to beat.

Two Hundred Fifty Watt-Hours Per Kilogram and the Battery Energy Wall Standing Between Electric Motors and Real Range
Why battery specific energy - not motors or software - is the physics wall blocking real range for electric aircraft, and when that changes.
VectorSolid-state batteries and the energy density wall that electric aviation must break to actually work
Solid-state batteries must reach 500+ Wh/kg to make regional electric aviation viable, but manufacturing breakthroughs are still years away.
