Introduction: In a paper published in the Journal of Scientific Exploration (Dullin & Jamet, 2018), a research on historical perspectives concerning the study of psychokinesis on lightweight spinning objects, and a methodology for conducting macro-pk tests on this kind of target, in a non-confined environment, were presented.  

In a paper published in the Journal of Parapsychology (Dullin & Jamet, 2020), new results were presented with two set of experiments: reference experiments with a static bench, where the motion of the target is obtained with the airflow issuing from a pump, and PKer (volunteer practicing Psychokinesis) experiments (with a new portable bench), where the motion of the target inside the bench is triggered by the PKer. The comparison between the airflow speeds around the target in the two sets of experiments showed that the tangential airflow speeds in the PKer experiments were 10 times lower than the required tangential airflow speeds to start the target moving in the reference experiments.  

This tends to prove that the motion of the target in these experiments cannot be attributed to thermal/aerodynamic effects. Compiling all the facts from the beginning of this research, discarding the different classic physical causes of the movement, the hypothesis of some macro-PK effects has been placed. 

In order to better qualify these effects, this paper present the analysis of the energies and forces (torques) involved in the two PKer experiments. The results will be compared also with others experiments using other kinds of targets. 

Precedent evaluation about energy involved in small PK has been done by Dr. Antonio Giuditta, in its experiments with a torsion pendulum at distance of one meter from the participant (Giuditta, 2014). 

Methods: To evaluate the energy and forces involved in these effects the following parameters are calculated: 

  • The moment of inertia J of the spinning target 
  • The maximum rotational speed reached Wmax 
  • The total friction torque T  
  • The maximum and average acceleration during the speed-up 

The target as in (Dullin & Jamet, 2020) is formed of three stacked hemispheric plastic domes placed at the top of the stem of a carousel candle (Figure 1) with a total weight of 7,35g 

Fig. 1 Mobile device used as a target: 3 stacked plastic domes on the top of a carousel. 

Using theses parameters, the following physical quantity are evaluated: 

  • The maximum kinetic energy reached.  
  • The average acceleration torque which represents the torque needed to speed-up the target.  
  • The total “motor” torque  

Results: The results deduced for the two PKer experiments show that the energy involved is in the range of the microjoule and the torque close to 0,1 micronewton.meter. This is to be compared with the work of Dr. Antonio Giuditta who evaluated the perturbation of his mobile device at 0.1 microjoule at one meter distance from the participant (Giuditta, 2014). 

Many other experiments (more than 400 with 7 experienced PKer) have been conducted in different contexts and with different objects.  

The maximum values reached were in the range of 20 microjoules for the kinetic energy and 3 micronewton.meter for the “PK” torque, either by a very fast spin of 210 deg/s and an acceleration of 1,2 deg/s/s of a light target, or by a slow spin of 11deg/s of an heavy target of 500g. The videos will be presented at the conference. 

These first results give a range of semi-repeatable effects situated between micro-Pk and larger macro-PK effects (as in poltergeist or exceptional medium case), the latter being more difficult to study because of their spontaneous character and their elusiveness. It could be worth to study further these small potential macro-PK effects to progress in the comprehension of these anomalous perturbations.

Focus on Macro-pk research with 2 directions: An experimental one working with PsychoKinesis practitioners in order to detect macro-Pk effect, validate them through detailed measurement, and study them to better understand the phenomenon. A non-experimental one by conducting a documentary and database work around mediumship, poltergeist, and human levitation from antiquity until now.
