Charge conservation property implies that if the current carried by the motion of a CDW is just
$$j = - n_o ev$$
charges have to be considered as completely liked to the phase. A deformation of the phase has to be associated with an uncompensated charge. The consequences would be the replacement of the soft phason mode by a plasmon like mode, and of the elastic response by an electrostically screened one. Preliminary results on a microscopic calculation, show that the phason exists and does not carry a K component for the density of charges.
