Query: The energy conservation law in hydrodynamics vs the pseudo-law of
  alternative energy. Comment on 'Alternative energy vs pseudoscience' and the
  papers cited and not cited therein   A series of papers in the ISJAEE Journal on 'dam-free hydroelectric power
station' concluded by paper: Zotyev, D. B., Alternative energy vs
pseudo-science, ISJAEE. 2013. 8(130). P.131-136, is reviewed and commented. A
comparison with the generally accepted energy conservation law in hydrodynamics
reveals a disappointingly low scientific level of the reviewed papers (both
pro- and contra- the dam-free concept), not excluding the published
peer-reviewer reports. In the present version we emphasize that the ISJAEE
journal published several papers, which neglect and reject the basic physical
concepts, such as the Bernoulli integral, the energy conservation law in
hydrodynamics, the wave function of photon and some others, with all these
rejected concepts being far beyond the scientific scope of the journal. Some
readers will be more concerned about the energy equation in hydrodynamics, in
its theoretical form or in the Bernoulli integral form as being more
traditional in technical hydromechanics. Some readers will be shocked with the
statement that a photon does not possess the wave function. Overall, in this
way or in that way, all readers will hardly stay unsurprised.
