Stirling Engine, vacuum Engine Cars for future

I was simply amazed by the videos of vacuum engine i checked recently in youtube. Here the engine is heated from outside (external combustion engine) and expands the air inside allowing the pistion to move.

Currently a flame is heating the engine, but think of future, what if this can be substituted by solar energy. Imagine a car with a huge lens mounted on top and the lens refracts the sun rays to point on the engine... pure solar energy, No fuel :) LOL!!! (see my diagram below)

Following are the youtube videos which caught my attention:
