And here's some news that promises not only to extend the range of automobiles but could perhaps result in large electric powered commercial aircraft in a period of time somewhat shorter than 50 years.

A Colorado Firm Claims It Can Triple the Power of Electric Engines

The company claims that, according to the Advanced Research Projects Agency-Energy (ARPA-E) guidelines, a propulsion system of a commercial aircraft such as Boeing 737 must deliver a continuous power density of 12 kW/kg. However, conventional electric motors can only generate a maximum of up to 4kW/kg. Thanks to its reduced weight, the HPDM-250's power density clocks up to an impressive 13kW/kg.

EDIT: I just looked it up and a Tesla Motor in at least 1 model weighs only about 70 pounds. So, it that is typical or close for other EVs I guess not much of a boost..
