Quick question, if we put an air tight box with a motorized propeller inside it on a balancing torsion pendulum (fig 1) will it spin?

 

If done following the following parameter it will not only spin but accelerate till the torsion halts the movement, first try we will put inside the airtight box a simple Lego motor/propeller on a pedestal off center (Note 1) (Figs 4 to 10, video 1), second try we will remove the pedestal and place the motor/propeller on a horizontal pendulum.

 

Description of the test assembly.

 

 

 

 

 

Fig 1

 

 

 

 

Fig 2a                                                                                     Fig 2b

 

The box has the following dimensions (Fig 2)

Height 1 meter.

Length 1.4 meters.

Width 1 meter.

Plus rounded rear and forward end with a 0.5 meter radius

 

A box with these dimensions has a volume of 2.18 cubic meters, therefore there are 54.634.954.084.936.200.000.000.000 molecules (that’s 54 septillion [2]) very fast moving molecules colliding with each other in random manner.

 

 

Fig 3

 

The propeller was constructed using an old PC power supply fan (1) with a Lego wheel (2) glued in it (fig 3).

Cardboard cut outs (3) were attached to the power supply fan to increase size (fig 3).

The resulting propeller was attached to a Lego Motor and installed on a pedestal inside the box (fig 4).

First try: Lego Motor on a pedestal

 

At first glance the set up may seem to be a “pulling by bootstraps” (fig. 5) mechanism.

But the moment the Lego motor is switched on it starts to spin proving that you definitely CAN PROPEL A CLOSED BOX FROM WITHIN WITHOUT EXPELLING MASS/PROPELLANTS.

Explanation?

 

This is how I explain what is happening (not necessarily what is actually happening, just what think is happening)

 

Fig 5

 

Inside our box we have 54 septillion very fast moving molecules colliding with each other in random manner (Fig 5)

 

Fig 6

 

We place the propeller inside the box with all the molecules (Fig 6).

 

Fig 7

 

When we spin the propeller we will have collisions between the propeller and the fast moving molecules (fig 7).

 

Fig 8

 

For every collision a force (red arrow) will be exerted on the propeller pushing it forward, as for every force there is an equal counterforce (blue arrow) the air molecule will be hurled in opposite (rear) direction.

 

 

Fig 9

 

The propeller will receive a number of “bumps” in the forward direction (red arrows) as numerous air molecules are accelerated in the opposite (rear) direction (fig 9)

 

Fig 10

 

The sum of the forward forces on the propeller (red arrows) will tend to average into a forward force (big red arrow) by sum of all the vectors (fig 10)

But the molecules that have been accelerated in the rear direction do not reach the box’s rear surfaces directly, they collide with other air molecules randomizing their vectors (see kinetic theory of gases) so part of the force the propeller exerted on the air molecules will be diverted towards all the inner walls, not just the rear wall.

 

 

Second try: Lego Motor on a horizontal pendulum.

 

Instead of putting the motor/propeller on a pedestal (Fig 10a) we position it on a horizontal pendulum (Fig 10b and fig 11)

 

 

 

Fig 10a                                                                                                     Fig 10b

 

 

 

 

Fig 11a                                                                                                                            Fig 11b (top view)

 

This setup will permit the motor/propeller assembly to rotate around the pivot (figs 10b and 11) between position Pos A and Pos B (fig 11b), when the motor/propeller reaches Pos B it will collide against the air tight box’s inside structure giving it a push, with every collision the box will gain acceleration.

After Christmas we are filming a demonstration of the Fluid Space Drive model 1 at the university (large room so box can easily be seen rotating 360 degrees and more)

 

 

Explanation?

 

One more time I will try to explain what is observed.

Fig 12

 

Inside our box we have 54 septillion very fast moving molecules colliding with each other in random manner (Fig 12)

We place the propeller inside the box with all the molecules (Fig 6).

 

Liberty of movement on the horizontal axis.

 

Fig 7

 

When we spin the propeller we will have collisions between the propeller and the fast moving molecules (fig 7).

 

Fig 8

 

For every collision a force (red arrow) will be exerted on the propeller pushing it forward, as for every force there is an equal counterforce (blue arrow) the air molecule will be hurled in opposite (rear) direction.

 

 

Fig 9

 

The propeller will receive a number of “bumps” in the forward direction (red arrows) as numerous air molecules are accelerated in the opposite (rear) direction (fig 9)

 

Fig 10

 

The sum of the forward forces on the propeller (red arrows) will tend to average into a forward force (big red arrow) by sum of all the vectors (fig 10)

But the molecules that have been accelerated in the rear direction do not reach the box’s rear surfaces directly, they collide with other air molecules randomizing their vectors (see kinetic theory of gases) so part of the force the propeller exerted on the air molecules will be diverted towards all the inner walls, not just the rear wall.

 

 

 

 

 

Important:

Although the experiment works exactly as described I am not suggesting we use this method to reach the proxima centauri system, for that please see main page for a description a more efficient use of the phenomena observed in this experiment.

Notes:

 

[1] The motor/propeller must not position in the exact center of the box or under specific conditions (low rpm/ weak power source) the box will turn but then stop and reverse direction (spooky).

For the box to accelerate the propeller must turn at 600rpm with a constant power source of 12 volts

If the rpm are increased beyond a certain threshold the box will not move at all, there is a “sweet spot” (12 volts) where the box will move as described

 

[2] Septillion (American) or quadrillion (European)

 

[3] Example B in fig.5 is often used to illustrate the futility of trying to move a boat/cart by blowing into a sail, however any person that takes a few moments to test the concept will observe that it DOES work, a low thrust is produced (See video, another and another).
