Not true at all: - no loss of power with insulated batteries - heat generated in battery pack and motor can heat the cabin with a heat pump - energy density

Not true at all: - no loss of power with insulated batteries - heat generated in battery pack and motor can heat the cabin with a heat pump - energy density in batteries is steadily increasing - price of batteries steadily decrease All of this would work with the tech from a current Tesla, but flight time will get acceptable in a few years. Car and truck are going to be 90% electric in a few years Planes are going to follow after, but not before.
