Weighing in on Electric Air Taxis

Your wish is a VTOL’s command, perhaps.

Key Takeaways:

  • While the automotive industry's shift to electric vehicles is influencing aviation, practical electric flight is currently limited to small, short-range aircraft due to significant battery weight limitations compared to fossil fuels.
  • Early attempts at larger electric fixed-wing aircraft have faced substantial development and safety issues, leading to a shift in investor focus towards small VTOL "air cabs."
  • These prospective "air cabs" confront numerous unresolved challenges, including lithium-ion battery flammability, high power demands for hovering, noise, complex air traffic control for urban environments, and highly optimistic cost projections, leading to skepticism about their near-term viability.

I never thought I’d see the day, but General Motors—among a number of other auto manufacturers, not to mention nations—has pronounced a death sentence upon the internal-combustion engine. Stays are possible, but permanent commutation is unlikely. It appears that electricity, in one form or another, may triumph in the end.
