The invention relates to a solid fuel decoupled fluidized bed gasifying method and a gasifying apparatus. In one aspect, the systems of the present invention take advantage of high NA optics to realize ultra high storage capacity. The bearing 10 co-operates with an abutment 18 on the rotor to form a thrust interface. A container handler configured to transfer at least one container tofrom a rail car and to report its container image, optical characteristic, container code estimate of the container, a rail car identifier estimate andor a container chassis identifier estimate.
