He reported that there are some experiments in which the charge is measured by a photon. The experiments were reproduced with confidence, allegedly giving the result higher approval ratings. So there you go ...
 There is a law of conservation of mass and energy. There is a mass-energy equivalence, which relates energy with mass by factor (speed of light squared). As a result, any value of the particle energy can be expressed in terms of its mass. Lack of weight indicates the absence of particles. Other forms of expression of energy in general - is the work, heat and pressure, multiplied by the volume. Work and heat reflect the kinetics of material particles. The energy of motion and heat require mass. Hence, the only alternative is pressure. Only the pressure wave can transfer energy without requiring the masses. But the principle of wave propagation of light is proven, repeatedly confirmed, and does not require additional evidence. ALL IN ALL! There is no existence of other forms of energy without mass.
 If the photon is a particle, count its size. Cannot? Why? The smallest particles defined by size.
 If the photon is a particle, specify the value of its energy. Cannot? Why every time, saying the emission of one photon, mean undefined amount of released energy?
 If the photon is a particle, what is its charge? Modern science claims that the photon has no charge.
Here it is, the last clue ... Found??

    First, let's define: if in fact we would suddenly discovered the charge, it will prove or disprove the theory of photon?
For no illusion, lets make the acquaintance with "the theoretical basis of" modern science 1, or better yet, with more details 2.
     Got it? Particularly good about the "... quantum-mechanical effect ...". Now finding the charge contradicts the theory itself...... 

    People do not understand that the particle charge is neither its parameter nor the fundamental constant. For those who want a bit more about it - I give references A and B.
     For the rest I'll explain: The charge is the coefficient of proportionality between the parameters of the particles field (the ratio of energy to the potential at this point of the field). For leptons, this ratio is preserved whith change of the radius (the coordinates of the point of observation) for the heavy particles do not. The reason is that heavy particles do not have time to change their orientation under the influence of magnetic forces. The differences between them, the more significant the closer the point of the field to the particle. That is why modern physics at short distances introduces such abstract terms as "strong and weak" interaction. In this way, it has to explain these deviations in the ratio of "energy / potential."
     For pseudoparticle "photon", which has no power and size, it is absolute nonsense.
What is observed in experiments by researchers? -The answer is simple: they see simple shift of free electrons. Yes, yes - under the influence of light, charged particles suffer pressure and occur their small movements in space. On the part of the light source occur uncharging of free electrons, and afterward - increasing their density. This phenomenon is well known-shifting of  layer of the ionosphere during the day-to earth, and at night backward. The same mechanism operates in the phenomenon of "red glow" of atmosphere. If you do find a charge, it will be positive. But there is no thing as photon.
     We would note that we can prove this very easily-it is only necessary to measure the potentials of space in front of and behind the front of the light. For the gaseous medium is almost an insurmountable problem, but for water is not. Pour into a transparent container of water, direct it to the light and measure, here the potential drop reaches a few volts!

 I can’t see the point for fighting with watermills anymore.
