'Impossible' rocket drive works and could get to Moon in four hours

I already knew the answer prior to my posting.  It has to do with displacement.  Aristotle got it right when he said  "... the celestial matter (bodies) has a propensity to restore force which it needs to sustain the steadiness of motion".  There is no motion by inertia, but there's illusion of it. The illusion of motion by inertia is maintained by the presence of phase displacement, proceeds with constant speed and in a state of inner quiescence (synchronicity). If phase displacement is eliminated, the motion stops.

The object moving to the top of the tube proceeds with constant speed and synchronicity due to phase displacement.  The object moving to the top doesn't do so by inertia or friction.

LOL, the float rises because the water falls.  The water is viscous.  From the instant that the float is released allowing the water to start falling around it, the viscous drag quickly matches the inertia limited acceleration due to gravity and the speed quickly stabilizes.  It is ordinary, text book kinematics.

LOL, so you think you see non-inertial behavior in that video do you?  Well you go right ahead and point to what behavior in that video you think is non-inertial.  Do you think the system does lose GPE as the float rises do you?  Well, let's see buckaroos:  When the float is at the bottom the center of gravity is higher than when the float is at the top.  Since the total mass does not change, that means that the initial condition has the greater GPE, ergo the GPE decreases, ergo the system loses energy as the float rises.  QED.

LOL, you have it inverted.  The screw converts its KPE as it rises into GPE.  The system loses no energy as the float rises.  How convenient of you to leave out KPE.

The float rises because it displaces the water and not the other way around.  The float pushes the water out of the tube as it rises, which is the restoring force needed to sustain it's motion.  Once again, you have the process inverted, LOL.

MarkE,

According to you, the water isn't allowed to fall and displace the screw until the screw is first released.  You're putting the effect before the cause.......and if you would put your text books to the side, then you would realize how you're putting the cart before the horse, ROFLMAO.

LOL.  Ignore reality all you want. Water loses GPE, pushes on the float, the float gains KE AND GPE during the rise and ultimately loses KE.  The system loses net GPE as the center of gravity falls throughout the process.  When the process is done the float has expended all KE gained during the upward traverse, and the column has lost GPE.  You are free to dispute by showing your work.  The floats rate of ascent is initially limited by the inertia of the float and the water.  As the ascent gains speed it is further limited by viscous drag.
