A system for preventing drowsiness in a driver by employing a thermal grill. The system includes a detection module and an intervention module. The detection module monitors a driver's parameters to determine whether the driver is drowsy. If the driver is determined to be drowsy, the intervention module activates a thermal grill with interlaced hot and cold regions. This activation causes the hot regions to approach one temperature and the cold regions to approach another. Additionally, this activation leads to an uncomfortable sensation for the driver, alerts the driver, and prevents the driver from getting drowsy.

A process and gas generator is disclosed for generating by dry distillation of solids and gasification of solids, a fuel gas substantially free of condensable dry distillationvolatiles which would interfere with the intended use of the gas, e.g. for powering an internal combustion engine.To achieve this, solids beds in distinct dry distillation and gasification zones are maintained under conditions favouring thermal cracking of condensable (tar) volatiles in the hot regions of both zones.
