Martin Lubich (aka loramel) created the rear wheeled monstor. Beautiful work with the crash test dummy adding another level of interest. Martin explains
how his creation works:
“The propulsion system will be two independently operating zero point energy
fueled engines - one per wheel - with the big air intakes acting as cooling
system. The zero point energy source is located between the two main wheels
and radiation shielded (but you can still see the blue radiation).
Since the mastering of ZPE (zero point energy) involves the unification of the
theories of quantum mechanics and gravitation, a practical side effect is
also the emergence of artificial gravitational devices, which in this case is
used to force the front wheel to the ground.”
