  We study properties of Wigner crystal in snaked nanochannels and show that
they are characterized by a conducting sliding phase at low charge densities
and an insulating pinned phase emerging above a certain critical charge
density. We trace parallels between this model problem and the Little
suggestion for electron transport in organic molecules. We also show that in
presence of periodic potential inside the snaked channel the sliding phase
exists only inside a certain window of electron densities that has similarities
with a pressure dependence of conductivity in organic conductors. Our studies
show emergence of dynamical glassy phase in a purely periodic potential in
absence of any disorder that can explain enormously slow variations of
resistivity in organic conductors. Finally we discuss the KAM concept of
superfluidity induced by repulsive Coulomb interaction between electrons. We
argue that the transition from the sliding KAM phase to the pinned Aubry phase
corresponds to the superfluid-insulator transition.
