Abstract: The present invention relates to a method for converting carbon dioxide into hydrocarbons by reacting magnesium with carbon dioxide to obtain magnesium oxide and carbon, reacting the carbon with hot water steam to obtain hydrogen (H2) and carbon monoxide, reacting hydrogen and carbon monoxide according to the Fischer-Tropsch method, or reacting the carbon obtained with earth alkaline metal oxide to obtain earth alkaline metal carbide and carbon monoxide, wherein the earth alkaline metal carbide is then reacted with water to obtain acetylene and earth alkaline metal hydroxide.

Abstract: A method and system for treatment of biological wastes for preparation of fertilizers is provided. The method and system involves mixing a biological waste with a dilute sulfuric acid in a predetermined ratio. The mixture of the biological waste and the dilute sulfuric acid is then filtered to obtain an organic slurry and an acidic liquid. Thereafter, the organic slurry is thermally cracked at an elevated temperature to obtain at least one of an ammonia gas, one or more flue gases, and char and ash. The method and system further involves utilizing the ammonia gas, the char and ash, and the acidic liquid for preparation of the fertilizers.

Abstract: A solar power conversion receiver is described. In one aspect, the solar power conversion receiver includes a circular glass envelope and an absorber tube encapsulated within the circular glass envelope. An annulus, positioned between the circular glass envelope and the outer perimeter of the absorber tube, is bifurcated by first and second fins operatively coupled to the circular glass envelope and the absorber tube. These fins create first and second annulus compartments that are substantially sealed off, or independent, from one another. The first and second fins are ductile and responsive to expansion and contraction of components in the solar power conversion receiver due to temperature effects. In one aspect, gas in the lower annulus compartment stratifies with cooler gas interfacing with the encapsulating glass envelope, and hotter gas interfacing with the hotter absorber tube, resulting reduced natural convection heat loss as compared to conventional glass encapsulated receivers.

Abstract: A method and system for purifying liquid using waste heat is provided. Initially, a liquid is mixed with an anti-sealant agent in a first filtering unit to form a liquid mixture. Thereafter, the liquid mixture is filtered in the first filtering unit to separate foreign objects from the liquid mixture. Subsequently, the liquid mixture is heated in a pipe arrangement connecting the first filtering unit and one or more second filtering units to generate steam. The steam obtained from the heated liquid mixture is then purified in the one or more second filtering units. Thereafter, the purified steam is condensed in the pipe arrangement to obtain the purified liquid.

Abstract: A method and system for managing heat energy in a fluid purification system is provided. Initially, air is compressed using one or more compressors to obtain a compressed hot air. Then one or more fluids are purified using the heat energy associated with the compressed hot air in one or more fluid purification units thereby releasing a compressed cooled air. One or more hot purified fluids are stored in one or more fluid storage tanks obtained in response to the purification of the one or more fluids. Thereafter, the compressed cooled air is heated using a heat energy associated with the one or more hot purified fluids to obtain a heated compressed air. Subsequently, one or more turbines are operated using heat energy associated with the heated compressed air to obtain an expanded cooled air. The expanded cooled air is utilized for cooling.

Abstract: The invention provides a system for processing organic material using solar energy. The system includes a flat mirror reflecting unit configured to rotate around a dual axis of the flat mirror reflecting unit in order to receive sunlight from the sun. The flat mirror reflecting unit reflects the sunlight in response to receiving the sunlight. The system further includes a fixed concentrating Fresnel mirror unit for receiving the sunlight reflected by the flat mirror reflecting unit. The system also includes a sliding tray unit which receives organic material. The sliding tray unit is positioned such as to receive the sunlight reflected by the fixed concentrating Fresnel mirror unit. The sliding tray unit receives the sunlight concentrating on a focal region of the sliding tray unit. Upon receiving the sunlight on the sliding tray unit, the organic material in the sliding tray unit is subjected to thermal processing using solar energy of the sunlight.
