    CHALLENGE ACCEPTED.

    My car contains a small micro-singularity levitating in a magnetic field. The engine feeds small amounts of matter into it, capturing a sizable fraction of the rest-mass of the infalling matter as usable energy. The fuel I choose to feed the black hole powering my car? Ordinary water.

    I have invented the water-powered car.
