  A model is presented for dissipationless energy transfer in cell microtubules
due to quantum coherent states. The model is based on conjectured (hydrated)
ferroelectric properties of microtubular arrangements. Ferroelectricity is
essential in providing the necessary isolation against thermal losses in thin
interior regions, full of ordered water, near the tubulin dimer walls of the
microtubule. These play the role of cavity regions, which are similar to
electromagnetic cavities of quantum optics. As a result, the formation of
(macroscopic) quantum coherent states of electric dipoles on the tubulin dimers
may occur. Some experiments, inspired by quantum optics, are suggested for the
falsification of this scenario.
