Abstract: The invention relates to a method for operating a power plant (1) for generating electrical energy for delivery to at least one consumer (16) by combustion of a carbonaceous combustible, wherein carbon dioxide (19) is separated from the flue gas (7) of the power plant (1), the separated carbon dioxide (19) is converted at least in part into a fuel (20), characterized in that the fuel (20) is combusted at least temporarily in at least one heat engine (4) so as to form a waste gas (8), and electrical energy is generated by the heat engine (4) and is delivered to at least one consumer (16), at least some of the thermal energy of the waste gas (8) being used in at least one of the following processes: a) for heating combustion air (10) of a power plant (1); b) for heating a process medium (14) of the power plant (1); c) in a drying of the combustible of the power plant (1); and d) in carbon dioxide separation.

Abstract: In an indication device for a motor vehicle used by a disabled person, in particular a person in a wheelchair, with the indication device including an illuminated sign which displays information that for parking of vehicles, sufficient space should be maintained to the entry door of the motor vehicle, at least one distance sensor or movement detector is fitted to the motor vehicle, such that vehicles which are parking too near are registered by distance measuring, and subsequently, illumination of the sign and an acoustic signal transmitter are activated for a specified period of time.
