NOVELTY - The vehicle has operational components dissipating waste heat, while the vehicle is functional. Heat recovery devices transfer proportion of the waste heat to heated material, where the vehicle is in motion when functional. A heat engine drives a generator, and the generator provides power to an electric motor or battery/energy storage device in serial hybrid configuration. Heated liquid is provided for human consumption, and service activity includes dispensing of heated food or inclusion of chilled liquid such that the vehicle includes a refrigeration system.    USE - Serial hybrid/passenger motor vehicle for facilitating service activity requiring dispensing of heated material e.g. food and beverage, in form of coffee in a construction industry.    ADVANTAGE - The vehicle allows the heated material to be heated by the waste heat generated by the vehicle's operational components, thus reducing power requirements of the vehicle for facilitating the service activity requiring dispensing of the heated material and reducing carbon dioxide emissions in the vehicle. The heat engine is switched off when the vehicle is stopped, thus reducing kerbside emissions in cities and towns. The vehicle charges a battery by mains electricity, thus reducing running costs or electricity. The vehicle minimizes use of heat exchangers so as to ensure safety and hygiene of users. The vehicle runs by electricity from the battery or via the generator powered by an internal combustion engine. The vehicle re-uses the waste heat so as to improve system efficiency, thus enabling reduction in energy used in the carbon dioxide emissions.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for performing a service activity requiring a dispensing of a heated material.
