A system for converting a biomass into a biofuel including a biomass processing station arranged to receive the biomass from a biomass harvester, output the biomass to a hydrothermal liquefaction (HTL) converter, and receive a processed biomass from the HTL converter. The system includes a conduit arranged to transport the biomass from the biomass processing station to the HTL converter and transport the processed biomass from the HTL converter to the biomass processing station. The HTL converter includes a heat exchanger arranged to transfer thermal energy from a geothermal heat source to the biomass to convert the biomass into the processed biomass. The system also includes a controller arranged to monitor conditions of the biomass at locations along the conduit and adjust operations of components along the conduit to, thereby, adjust the conditions of the biomass at one or more locations along the conduit.

An apparatus comprising an actuator for moving an actuator rod and a bioreactor vessel is disclosed herein. The bioreactor vessel comprises a container for holding a liquid, a mounting for mounting a tissue sample in the container, and, an actuator coupling to enable the actuator rod to be connected for applying mechanical force to the tissue sample. The apparatus also comprises a seat, fixed with respect to the actuator and configured for locating the reactor vessel in a location selected so that the actuator can be connected for applying said force via the actuator coupling. The reactor vessel is removable from the apparatus.
