The comment to the offer of new revolutionary technology of an electrochromism.

In the retrospective plan by us has been opened electrochromic effect in films pentoxide niobium and it is proposed on its use as the modulator of light (for example, in the form of displays) in the patents given out by patent departments of the leading western countries and advancing Deb’s patents, an electrochromism considered by «father» (see site NREL).
Our patents differ from concepts of Deb flat refusal of use as the modulator of light of films WO3 for following reasons. In chemistry it is possible to find certificates of metastability of a condition in any directory or the textbook trioxide wolframium which dissolves even in water and it is subject to hydration up to jelly-like conditions. Besides there is a specific feature of behaviour WO3 in electrochromic process. At sign-variable repeated loading in trioxide wolframium there are phase changes to change of symmetry (for an amorphous condition at a level of near order{sequence}), and it in process of repeated loading conducts to increase in entropy, i.e. irreversibility of process.
All this has led to that during decades in the West was not possible to create efficient, commercially successful sample electrochromic display or a controlled window light filter — electrochromic smart window.
Realizing about insuperable lacks WO3, we unlike Deb and his followers choose essentially another material authority the concept in which basis use for realization electrochromic principle of modulation of light of films pentaoxide niobium lays. Nb2O5, as well as Ta2O5 differs extremely high reagent resistance, match with platinum — dissolves only in etching acid, not hydrated, that does problemless its contact to electrolytes, at repeated loading phase changes occur only in one zone of homogeneity that does not result in degradation electrochromic properties. The important difference is that colouring of films Nb2O5 occurs in a scale grey (from transparent up to black), instead of dark blue as at WO3. It is consequence of that absorption of light quantums occurs on mechanism Drude which provides also much more intensive plasma reflection of an infra-red component.
However, since time of handing over of patent Deb and on present time of film Nb2O5 did not become a subject of application and even their research electrochromic properties. It speaks that in films Nb2O5 obtained in the same technological ways, as films WO3 — vacuum condensation of any version, anodizing, electrophoresis, etc., electrochromic effect is displayed extremely slightly unlike WO3 where it is always intensive enough.
By us it has been accepted{it has been taken over;it has been assumed} essentially new material authority (from the point of view of an electrochromism) the concept. And researches have shown the analysis, that the reason low electrochromic efficiency of films Nb2O5 are kinetic difficulties of thermodynamic character. This circumstance is reflected in applied below clause where on the basis of these representations process of initiation intensive electrochromic effect on an example of their reception by anodizing is simulated.
The success of this model specifies a path of initiation intensive electrochromic effect at other technological ways of reception of films, including vacuum condensation.
