(Actually, it's an artist's conception of a ?Lunar construction vehicle from Project Horizon, a 1960 US Army study of feasibility of constructing a scientific / military base on the moon.?)
 
Lets just say it needed 100hp to dig in reduced gravity. No air, so that combo scraper/dozer used electricity. From where? Lead acid battery? too hot and too cold. OOPS. No air. Photovoltaic that must be it but no power cord. Jim
 
Why are the wheel treads backwards? The laws of physics still apply on the moon, no traction that way?

Artist must not have went to engineering school......

Way ahead of its time--Just like we know this one is fake because jet fuel was not invented yet in the 1860's---Tee
