Abstract: A motor vehicle includes a picture generation unit emitting a light field containing an image. A reflecting device is positioned to reflect the light field toward a windshield such that the light field reflects off of the windshield toward a human driver of the motor vehicle, and such that the image in the reflected light field is visible to the human driver as a virtual image. The reflecting device is at least 500 millimeters from the picture generation unit.

Abstract: A trough lining assembly is placed in a series of troughs at a biomass processing facility. The trough lining assembly includes a waterproof liner that lies against the sides of a trough, an aerator, and a retention mechanism that retains the aerator at the bottom of the trough. The aerator provides continuous aeration of biomass present in the trough by releasing aerating gas into the biomass along the length of the trough. The continuous aeration also churns the biomass, exposing more of it to the aerating gas and to sunlight. The trough lining assembly improves the efficiency of algae production by stimulating photosynthesis and consumption of carbon dioxide. The trough lining assembly has low production, transportation, installation, and maintenance costs.

Abstract: A trough lining assembly is placed in a series of troughs at a biomass processing facility. The trough lining assembly includes a waterproof liner that lies against the sides of a trough, an aerator, a nutrient line, and a retention mechanism that retains the aerator and nutrient line at the bottom of the trough. The aerator provides continuous aeration of biomass present in the trough by releasing aerating gas into the biomass along the length of the trough. The continuous aeration also churns the biomass, exposing more of it to the aerating gas and to sunlight. The nutrient line provides fertilizing nutrients to the biomass along the length of the trough. The trough lining assembly improves the efficiency of algae production by stimulating photosynthesis and consumption of carbon dioxide. The trough lining assembly has low production, transportation, installation, and maintenance costs.

Abstract: Algae production systems and associated methods are disclosed herein. In one embodiment, for example, an algae production system can include a plurality of elongated growth receptacles arranged in a desired configuration at a work site. The growth receptacles have a generally non-circular cross-sectional profile and are configured to hold an algae culture, and wherein the individual growth receptacles have a generally non-circular cross-sectional profile. The system can also include a carbon dioxide (CO2) subsystem configured to supply provide CO2-enriched air to the growth receptacles, a fresh medium subsystem configured to supply a fertility solution to the growth receptacles, and a harvesting subsystem.

Abstract: An apparatus for producing algae circulates algae fluid through flexible reactor tubing that is at least partially translucent to sunlight. The reactor tubing lies flat when not pressurized. Preferably, the reactor tubing is made of clear polyethylene with UV inhibitors, the polyethylene being between 6 and 15 mil thick. The reactor tubing preferably has a substantially circular cross-section with a 6 inch diameter and is preferably 1250 feet long. Gas relief valves allow gases generated during algae production to escape from the reactor tubing. CO2 may be injected into the algae fluid to stimulate photosynthesis. A circulation pump propels the algae fluid through the reactor tubing, keeping the reactor tubing pressurized and stationary without touching the reactor tubing, so that a rigid support structure is not needed. One or more layers of plastic mulch may be disposed above or below the reactor tubing to control temperature and sunlight exposure.
