The video does not say how this hyperloop (engine) works can any one explain?
Eventually, linear induction would be the propulsion method as others have indicated, especially at speeds approaching Mach 1.
At the moment there are three camps of thought on how to support the pod in the tube, and these in turn would be relevant to the choice propulsion tech. These include air bearings, maglev, and wheels. Wheels would likely be the simplest choice for lower speed beta versions, and if wheels are chosen, a simple rotational motor driving the wheels becomes a cheap possibility. Linear induction drive entails deploying electromagnetic drive mechanisms at least periodically (if not continuosly) through the length of the tube. Also, some sort of emergency deployable wheels are likely to be a requirement regardless of the choice of operational pod support.
