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

LOL, you are of course joking.  The video demonstrated that water that has been lifted up by expending work falls right back down given the chance.

This isn't about the water being lifted by expending work and falling back down when given the chance.  This is about an object moving without inertia.  If you claim it's moving by inertia, then you must show where and how the object itself is releasing energy to do so.  And, you must show that the system has lost energy by moving the object to the top.

You are welcome to present whatever you want, obfuscated however you like.

The computer program will give a much better visual. Also, much easier to show more than 2 rocks being thrown from the boat, which doesn't really give much more of a visual than without the calculations.  Also, the parameters can be easily changed to run different variations, so we can compare your wrong visual to the correct visual of the hypothetical.

   gravityblock you've been a bit "lost" with a few of your latest analogies.
   Maybe you can program computers but just think hard as to why the
   little screw floats up the tube. Just use known science to work out the
   metronomes.
     I agree that with a "hypothetical" case you can bend the rules if you
    want to.
       Can "dogma" exist as it used to in these days of rapid communication
    between the more or less whole population of the world? The brightest
    minds get to cast their "eagle eyes" over all this stuff.
       I love this forum because it's not censored to death, everyone has their
    own ideas and the reader can choose to follow a contributor or not as the
    reader chooses.

Just because it's a hypothetical thought experiment, doesn't mean it's bending the rules.  Who's to say the hypothetical couldn't be done in a real life experiment.  The momentum issue could be solved along with the position for the source of rocks in a controlled environment.  Mythbusters successfully canceled the forward and backwards momentum of shooting a soccer ball from a moving truck, and it wasn't even done in a controlled environment.

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, 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 doesn't 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.
