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

Here's a video demonstration showing how to lift an object really high with very little input energy.  And it uses the atmospheric pressure and a vacuum to do so.  Oh, and a perfect vacuum isn't necessary.  How does this not qualify as a reaction-less drive?

Wouldn't it be easier to just lift up the screw rather than lift up a big column water so the screw can float up ?

Of course if there is a column of water stuff that floats will umm... float up in it. wow.

At 1m50s of the video we can see a convex shape formed at the boundary between the water and the air.  If the water is being displaced as the air is rising in the tube by a greater force from below, then we'll see a convex shape formed at the boundary, and this is what we see.  The air is rising in the tube by the greater atmospheric pressure from below, and the water forms a convex as it's being displaced by the rising air.

This has nothing to do with what method is the easiest to lift up the screw.  This has to do with motion without inertia through phase displacement.  Wow, you really missed the boat, ROFLMAO!

The buoyancy was just enough to float the screw.  If you submerged this float under a column of water, it won't float up as you suggested....unless there is a pressure differential.  You missed the boat once again!

This is another inversion of the truth.  In this case, the greater force is the atmospheric pressure and not the gravitational force.

LOL, and what sets the atmospheric pressure hot shot? Oh, that would be the weight IE the gravitational force on the air.

How convenient of you to leave out the atmospheric pressure.  This is similar to there being a greater force as we found in the blowing your own sail example.

Watch the video again.  When he lifts the tube out of the water, the atmospheric pressure forces air into the tube.  The atmospheric pressure wouldn't be able to fill the tube with air if the gravitational force on the water is greater.  The water then begins to fall out of the tube at the rate the tube is being filled with air by the atmospheric pressure.  If the gravitational force on the water is the greater force, then we wouldn't see the tube filling up with air, and all of the water would fall out of the tube at nearly the same time at the acceleration rate of gravity (it would be like turning a full glass of water with no lid upside down).  You have inverted the effect for the cause, and you have inverted the direction of the force for the prime mover.

LOL.  Are you trying to compete with MM in some sort of crackpot competition?  The water and everything else in the local environment is subject to the surrounding air pressure caused by the force of gravity on the atmosphere from the local elevation on up.
