Can eVTOL vehicles be green? Specifically, can eVTOL vehicles be more energy-efficient than cars? Particularly, can eVTOL automobiles be more energy-efficient than cars and trucks? Our current Heaviside model utilizes about 120Wh per passenger mile, and does so at two times the speed of the Leaf: 100 miles per hour (of course, we can fly much quicker, if we choose). Why is Heaviside this efficient– doesn’t it take more energy to go faster? This is not simply observation, but can be mathematically shown. Heaviside is rather energy-efficient….
