A hybrid system for generating electrical power. The hybrid system includes a photovoltaic array for collecting and converting solar radiation into electrical power, an apparatus for producing power from a source of liquid fuel, the apparatus including at least one capillary flow passage, the at least one capillary flow passage having an inlet end and an outlet end, the inlet end in fluid communication with the source of liquid fuel, a heat source arranged along the at least one capillary flow passage, the heat source operable to heat the liquid fuel in the at least one capillary flow passage to a level sufficient to change at least a portion thereof from a liquid state to a vapor state and deliver a stream of substantially vaporized fuel from the outlet end of the at least one capillary flow passage, a combustion chamber in communication with the outlet end of the at least one capillary flow passage and a conversion device operable to convert heat released by combustion in the combustion chamber into electrical power, and a storage device electrically connected to the photovoltaic array and the conversion device for storing the electrical power produced by the photovoltaic array and the conversion device.
