Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek φῶς, phōs, "light", and σύνθεσις, synthesis, "putting together". In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies all of the organic compounds and most of the energy necessary for life on Earth.
Efficient LED lamp for enhancing commercial and home plant growth
InactiveUS6921182B2Control growth rateControl inventoryElectrical apparatusPoint-like light sourceGrowth plantLight beam
A first set of orange LEDs with a peak wavelength emission of about 612 nanometers, a second set of red light emitting LEDs with a peak wavelength of about 660 nanometers, and blue light LEDs. Two beam spreads, 15° and 30°, were provided for both the 660 nm LEDs and 612 nm LEDs. When directed perpendicularly upon tops of the plant leaves, 10% light transmission occurred through the leaves for the 30° LEDs, and 80% light transmission for the 15° LEDs. Thus, fully 50% of the orange / red spectrum primarily used for photosynthesis was transmitted through the upper leaf canopy, making it available to support photosynthesis in leaves below. LED lamps are positioned at varying distances from the growing plants for controlling plant growth rates that vary with these distances, thereby to control plant inventory, because growth of plants can be greatly slowed to preserve them during periods of slow sales.

This process is unique in photosynthetic carbon sequestration. An on-site biological sequestration system directly decreases the concentration of carbon-containing compounds in the emissions of fossil generation units. In this process, photosynthetic microbes are attached to a growth surface arranged in a containment chamber that is lit by solar photons. A harvesting system ensures maximum organism growth and rate of CO2 uptake. Soluble carbon and nitrogen concentrations delivered to the cyanobacteria are enhanced, further increasing growth rate and carbon utilization.

Trophic conversion of obligate phototrophic algae through metabolic engineering
Most microalgae are obligate photoautotrophs and their growth is strictly dependent on the generation of photosynthetically-derived energy. In this study it is shown that the microalga Phaeodaclylurn tricornutum can be engineered to import glucose and grow in the dark through the introduction of genes encoding glucose transporters. Both the human and Chlorella kessleri glucose transporters facilitated the uptake of glucose by P. tricornutum, allowing the cells to metabolize exogenous organic carbon and thrive, independent of light. This is the first successful trophic conversion of an obligate photoautotroph through metabolic engineering, and it demonstrates that methods of cell nourishment can be fundamentally altered with the introduction of a single gene. Since strains transformed with the glucose transport genes are able to grow non-photosynthetically, they can be exploited for the analysis of photosynthetic processes through mutant generation and characterization. Finally, this work also represents critical progress toward large-scale commercial exploitation of obligate phototrophic algae through the use of microbial fermentation technology, eliminating significant limitations resulting from light-dependent growth.

Low emission energy source
A power generator provides power with minimal CO2, NOx, CO, CH4, and particulate emissions and substantially greater efficiency as compared to traditional power generation techniques. Specifically nitrogen is removed from the combustion cycle, either being replaced by a noble gas as a working gas in a combustion engine. The noble gas is supplemented with oxygen and fuel, to provide a combustion environment substantially free of nitrogen or alternatively working in 100% oxygen-fuel combustion environments. Upon combustion, Very little to no nitrogen is present, and thus there is little production of NOx compounds. Additionally, the exhaust constituents are used in the production of power through work exerted upon expansion of the exhaust products, and the exhaust products are separated into their constituents of noble gas, water and carbon dioxide. The carbon dioxide may be used in conjunction with a biomass to accelerate the biomass growth and to recover the oxygen enriched air resulting from algae photosynthesis for enhancing the operation of the power generator using the as Biomass for processing into methanol / ethanol and biological oils as fuel for the power generator. The biomass fuel is seen as a solar fuel and may be used in conjunctions with other solar fuels like heated thermal oil and others, as well as clean fossil fuels to optimize to clean, and efficient operation of the power generator in various regulatory contexts.
