Summary

The guest, an electric aircraft founder, explains how Elon Musk's 12-year-old MIT AeroAstro talk set a battery energy density threshold of 400 Wh/kg for electric regional and continental flight. He says the industry has now reached that threshold, after conventional jet engines hit a dead end. As a result, he believes electric and hybrid-electric aircraft will revolutionize aviation, starting with regional and continental routes rather than transatlantic flights.

  • The speaker says he was working on jet engines and saw the field hitting a dead end.
  • He recalls Elon Musk's MIT AeroAstro speech 12 years ago about electric planes.
  • Musk calculated that electric flight starts to make sense at 400 Wh/kg gravimetric energy density.
  • The speaker says the industry is now at that 400 Wh/kg threshold.
  • Electric and hybrid-electric aircraft are expected to work first for regional and continental flights, not ocean-crossing routes.
  • The broad investment implication is bullish for electric and hybrid-electric aircraft.

Electric/hybrid aircraft will revolutionize regional aviation.
Electric and hybrid-electric aircraft are now at an inflection point for regional and continental flights because gravimetric battery energy density has reached roughly 400 Wh/kg, the threshold Elon Musk calculated 12 years ago at which electric flight starts to make sense; this will let electric/hybrid aircraft replace a dead-end conventional jet engine path and revolutionize aviation.
