Good question! Many teams are using induction maglev. Regular maglev technology required either permanent magnetic tracks or expensive electronically controlled tracks with embedded electromagnets, but induction maglev requires only a conductive plate on the floor (the hyperloop test track uses aluminum)[1] and a "hover module" which induces eddy currents in the floor and repels off them.[2] Based on their spec sheet the current generation of technology consumes 66 watts per kg of lifted mass, and since it's a constant power draw the faster you go the less energy it uses per mile.
