     I'm not sure if it is even possible to liquefy woodgas, but it
certainly isn't economically feasible. Seems like, IIRC, it just can't
be done.

           Primarily CO and H, with some methane. Note that methane
isn't compressible to liquid by itself either. Nor is H, which is one
of the major problems with going to a hydrogen energy system.
