The apparatus includes a chamber having air disposed therein, a pulsed laser for converting an energy source into light pulses, and a lens for receiving the light pulses and directing the light pulses toward a focal point within the chamber. Each light pulse converges in a region which is proximate to the focal point and causes molecules within the air which are at the region to disassociate. Disassociation of the molecules generates pressure waves which provide thrust for powering the object to move.Other References
