Background

  • The idea to power aircraft with electric motors has been around a long time

    • Patents filed in 1943 for both battery and piston-engine hybrid electric airplanes

    • Progress limited by key technology barriers

      • >

        A source of electricity with power and energy densities suitable for aircraft

        • >

          Electric motors with high power/weight ratios

  • What has changed

    • Environmental concerns are accelerating development of electric power-system technologies that have the potential to overcome the historical barriers
