摘要:
A photo-bioreactor can be arranged to receive incident solar radiation. The photo-bioreactor can contain photosynthetic organisms. The photosynthetic organisms can be genetically modified to produce an organic substance. The organic substance can be a biofuel or a precursor to a biofuel. The precursor can be isolated and converted into a biofuel. The biofuel can be extracted from the photo-bioreactor for use, for example, in energy generation or as a fuel.
摘要:
A method of growing algae is described that is part of a cogenerational energy production plant in which solar energy from a solar collecting and concentrating field is used to provide photonic energy for the growth and stress phase of algae as well as to provide heat for driving a turbine. The supplementary energy for the power plant is provided by natural gas and by biomethane that is produced by fermentation of the algal biomass. The carbon dioxide that is a by-product of the combustion of both the natural gas and the biomethane is recycled to provide the carbon source for the algal growth.

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.

A multi-mode solar power generation system can include a first energy conversion system that generates electricity from a working fluid heated by a portion of solar radiation focused by a plurality of heliostats. The multi-mode solar power generation system can also include a second energy conversion system that generates electricity from an unused portion of the focused solar radiation using a different energy conversion mode than that of the first energy conversion system. The second energy conversion system can include one or more photovoltaic converters, which directly convert solar radiation to electricity. The unused radiation from the first energy conversion system can include radiation spillage or dumped radiation from a thermal receiver of the first energy conversion system.

In an automatic decision-making system, a method and a tool for the reduction of the dimension of data mining, which is automatically coupled to an empirical predictor of the system. The method includes a qualitative modeling of the interrelations between various objects whose attributes are relevant to a score made by the predictor according to which decisions are made, wherein this relevancy is determined by an input of a domain expert to the problem in hand. The model is called a Knowledge-Tree and its conclusions are represented by a graphical symbolization called the Knowledge-Tree map. Data mining, which follows the construction of the Knowledge-Tree map regards only datasets which are associated with logical and validated branches of the knowledge tree. Because the expert input which reduces the dimension of data mining was completed prior to data mining, interception by human reasoning is not needed after data mining and the decision making process can proceed automatically.

摘要:
An electrical power storage unit has one or more metal-gas electrical cells, each cell including a pair of generally planar outer electrode units configured to define therebetween an interior space for containing an electrical power storage medium and an inner electrode unit mounted between the pair of outer electrode units so as to be in electrically conductive contact with the electrical power storage medium and define a plurality of volumes each having a pair of open ends, each open end facing an adjacent outer electrode unit. The power storage medium is a slurry containing active metal particles and an electrolyte solution. The inner electrode unit is configured for removable insertion within the interior space. The volumes defined by the inner electrode unit are configured so as to contain portions of the power storage slurry such that removal of the inner electrode unit from the interior space causes the simultaneous removal therefrom of the major part of the power storage slurry. Each outer electrode unit includes a generally planar gas electrode, a device for separating the metal particles from the gas electrode, and a device for preventing mechanical damage to the device for separating upon removal of the inner electrode unit from the interior space and upon insertion of the inner electrode unit into that space.
