The concept is realistic. Solar panels can supply electric energy to propel a vehicle but the engineering is tricky.
Solar panels require a lot of real-estate to make usable electricity, and size is an automobile's efficiency enemy.
Lightyear Automotive, Helmond, NL, is introducing the Lightyear Zero as the first practical solar electric car.
At a cool €250,000 each, the Lightyear Zero is the "wealthy testbed" for more affordable cars in the future.
Much has been made over electric vehicles with hub-mounted motors inside the wheels.
The first such car I ever heard of is the Lohner-Porsche Elektromobil of 1898.
Porsche was able to locate the only known surviving Elektromobil for a complete restoration.
It now sits proudly in the Porsche Museum, a testament to Prof. Ferdinand Porsche's engineering genius.


Sounds great in the rain.
