Demonstrated By: Fusion research centers (ITER, MIT, etc.)
What Happens:
Charged plasma is held in mid-air inside a vacuum chamber by strong electromagnetic fields shaped into a “magnetic bottle” — a containment field that the plasma cannot escape from without energy loss.

Relevance:
This proves that massive energetic matter can be physically constrained using only a well-shaped EM field. While plasma isn’t a car, the same confinement principles could theoretically apply to field-tuned vehicles.
