A motor vehicle having a unit, particularly a drive assembly, which is operated by a fuel that is cryogenically stored in a vehicle tank, is provided, in which fuel is heated by a heat exchange with a warmer medium. The fuel taken from the vehicle tank comes in contact with the cold side of a thermoelectric generator, particularly in the form of a Seebeck element, in order to generate electric current for the electric power supply of the vehicle. The warm side of the thermoelectric generator is preferably acted upon by the warmer medium also used for the heat exchange with the cold fuel, in which case the thermoelectric generator may be integrated in a heat exchanger for the heat exchange between the fuel taken and the warmer medium.

The invention relates to an adhesive insulating system (3) that is non-destructively removable, e.g. for repair purposes, for sound insulation of partition walls (1), particularly in motor vehicles. Between the foundation and the overlying layers of the insulating system (3) a layer (2) of a highly under-cross-linked polyurethane material or a special bitumen mixture is applied that has a strong adhesive effect and thus enables a force-locked connection to be made between the foundation (1) and the insulating system (3). To ensure that the desired flexibility is obtained together with unchanged acoustic effectiveness even when a carpet (8) is laid on the insulating system (3) or its heavy layer (6), according to the invention a decoupler (7) of soft elastic, predominantly open-pored material is arranged between the carpet (8) and the heavy layer (6). Surprisingly, along with the desired flexibility, the acoustic effect is further improved.
