Looked up paul davies and he is not a controversial physicist, and have gone on NASA website and read that indeed negative energy can produce propulsive force.

In 1863 gliding under gravity works by changing the lift to provide propulsive force as the airship alternately rises and sinks, and so does not need a powerplant.
23.
For when she is underway every element of resistance, stability, weight, heeling effort, and propulsive force is in one transverse plane, and that plane is the boat's midship section.
24.
Presumably, she animates the wings to flap or somehow generates a propulsive force with her powers, since her airborne speed and maneuverability to date extend well beyond simple gliding.
25.
Prucalopride, a first in class benzofuran, is a selective, high affinity serotonin ( 5-HT 4 ) receptor agonist that stimulates colonic mass movements, which provide the main propulsive force to defecation.
26.
Reducing the propulsive force carried by the front tires leaves more adhesion for steering the vehicle into a tight bend or for holding a cornering arc in the middle of a turn.
27.
Leg extensor muscles, important in standing and providing propulsive forces during walking, are capable of generating forces of hundreds of pounds, while the arm extensor forces are measured in tens of pounds.
28.
The tendency, especially of fold mountains ( e . g . the Cordilleras ) to produce roughly parallel chains is due to their rock structure and the propulsive forces of plate tectonics.
29.
The diagnostic criteria for inadequate defecatory Propulsion is given as " inadequate propulsive forces with or without inappropriate contraction or less than 20 % relaxation of the anal sphincter during attempted defecation ."
30.
Adjusting the angle of attack while wing beat frequency is held constant, birds are able to direct a component of the lift produced by their wings backwards, thus producing propulsive force known as thrust.
