Helix to power moving vehicle

  1. Apr 13, 2010 #1
    A wheel rolling on a shallow rotating helix can be used to provide off vehicle power to a moving vehicle.
    Does anyone know of any applications where this is used, or know of any research into the matter?

    The helix is rotating, so what's providing power to it?

    Power to the helix

    Power to the helix could be provided from many sources, so long as it keeps constant rotational velocity while under or not under load.
