  The Nernst coefficient for the quasi-one-dimensional metal,
Li(0.9)Mo(6)O(17), is found to be among the largest known for metals (~500
microV/KT at T~20K), and is enhanced in a broad range of temperature by orders
of magnitude over the value expected from Boltzmann theory for carrier
diffusion. A comparatively small Seebeck coefficient implies that
Li(0.9)Mo(6)O(17) is bipolar with large, partial Seebeck coefficients of
opposite sign. A very large thermomagnetic figure of merit, ZT~0.5, is found at
high field in the range T~35-50K.
