Method for producing algae in photobioreactor

InactiveUS20090151241A1Increasing solubility of carbon dioxidePromotes algae growthAlgae productsSeed and root treatmentHigh concentrationSolubility
The present method transfers carbon dioxide in increased concentrations using perfluorodecalin for growth of algae in a photobioreactor. First, a perfluorodecalin solution is provided and mixed with a biological growth medium and a surfactant. The biological growth medium, perfluorodecalin solution, and surfactant mixture are then emulsified by circulation in a high-pressure emulsifier. The emulsified biological growth medium, perfluorodecalin solution, and surfactant mixture are then added to a photobioreactor containing algae capable of photosynthetically utilizing carbon dioxide. After adding carbon dioxide to the photobioreactor, the carbon dioxide dissolves in the perfluorodecalin solution at a higher concentration than in the growth medium. Conditions sufficient for the algae to perform photosynthesis using carbon dioxide from the perfluorodecalin solution are maintained thereby increasing the growth rate of the algae in increased concentration of carbon dioxide due to the increased solubility of carbon dioxide in the perfluorodecalin solution.

Helmet and body armor actuated ventilation and heat pipes

The lack of air flow under body armor, helmets, and thick garments can lead to excessive moisture build up and discomfort on the wearers body due to lack of heat removal and effective evaporation of sweat. By incorporating wick covered heat pipes or thermal conductors with air flow channels in the apparel contact area between the garments, helmets, and body armor the effectiveness air flow cooling and evaporation of sweat can be restored. Humidity or temperature auto-actuated bi-material valves are used to control this air-moisture-heat flow to achieve a controlled comfortable humidity-temperature environment and avoid excessive cooling. Supplementary air pumps, filters, dehydrators, fluid pumps, heating fluids, and cooling fluids may be incorporated to enhance the effectiveness. Biocides and hydrophilic materials are also incorporated on the wick coverings to avoid biological growth and maintain performance to achieve a healthy environment for the wearer.

Microbially-assisted water electrolysis for improving biomethane production

A method of producing in a bioreactor a biogas rich in methane involves electrolyzing water in an aqueous medium at a voltage in a range of from 1.8 V to 12 V in the presence of electrochemically active anaerobic microorganisms that biocatalyze production of hydrogen gas, and, contacting a species of hydrogenotrophic methanogenic microorganisms with the hydrogen gas and carbon dioxide to produce methane. Volumetric power consumption is in a range of from 0.03 Wh / LR to 0.3 Wh / LR. Current density is 0.01 A / cmE2 or lower. The voltage is sufficient to electrolyze water without destroying microbial growth. Such a method results in improved electrolysis efficiency while avoiding the use of noble metal catalysts. Further, a combination of water electrolysis with anaerobic degradation of organic matter results in increased biogas quality and in increased biogas quantity and yield. Oxidation of hydrogen sulfide contributes to the increased quality, while an increase in the rate of organic matter hydrolysis and an increase in the production of methane from hydrogen contributes to the increased quantity and yield.
