Topic: Novel Types of Windmill-Electric Generation Plants
Abstract: One of the main disadvantages of the existing windmill-electric generation plants is their low energy efficiency that equals not more than 20% (if the wind turbine axis is horizontal) or 35% (if this axis is vertical). It is conditioned by low level of the wind energy utilization by the wind turbine current types.
In principle, it is possible to increase the wind generators energy efficiency by the increase of the aerodynamic force of lift (i.e. lift) acting on blades of wind turbine (both in a case when the wind turbine axis is horizontal, and in a case when this axis is vertical). But unfortunately at present all known methods of creation of lift are already completely used.
The author of this paper worked out the design principles for creating novel types of windmill-electric generation plants. The application of these principles will allow increasing considerably energy efficiency of wind generators. These novel principles of wind generators design are the following. First, the use of novel principle of creation of the aerodynamic (and also hydrodynamic) force of lift that was discovered by the author of this paper. Second, the use of the positive feedback for electric power supply of the energy sources of wind turbine blades. The combined application of the above mentioned principles allows increasing considerably the output electrical power of a wind turbine of the novel type in comparison with the existing wind generators (by a factor of 1.5-2.0).

Topic: Solar Energy and Nanowire Solar Cells
Abstract: Solar cells based on nanocrystals, nanowires and their composites are often referred to as the next generation photovoltaic devices and have attracted much attention in scientific community as well as industries. The advantages of this type of solar cells include reduced reflection, light trapping capability, improved band gap tuning, and increased defect tolerance, which are expected to reduce the quantity and quality of materials necessary to reach high efficiency and allow for cost reductions. The increased interfaces, however, often lead to an increased charge recombination which has a negative impact on the energy conversion efficiency. This talk will address the progresses in nanostructure based solar cells, with an emphasis on nanowire radial junction devices. Current challenges in nanowire solar cell research will also be discussed.

Topic: Feasibility Study on Redox Mediator-Stimulating Bioenergy Extraction Using Edible Flora for Sustainable Applications
Abstract: This first-attempt study used extracts of appropriate antioxidant-abundant Camellia and non-Camellia tea and medicinal herbs as model ESs to stably intensify bioelectricity-generating performance in microbial fuel cells (MFCs). As electron shuttles (ESs) could stimulate electron transport phenomena by significant reduction of electron transfer resistance, the efficiency of power generation for energy extraction in microbial fuel cells (MFCs) could be appreicably augmented. Using environmentally friendly natural bioresource as green bioresource of ESs is the most promising to sustainable practicability. According to power-density profiles, supplement of Camellia tea extracts would be the most appropriate, then followed non-Camellia Chrysanthemum tea and medicinal herbs. As antioxidants could scavenge free radicals and active oxygen groups, their electrochemical characteristics were also closely related to electron transfer (ET) capabilities. Cyclic voltammetric analysis also indicated that several test extracts owned promising redox-mediating capabilities to be either antioxidants or ESs. In addition, antioxidant activities, total phenolic contents and power stimulating activities were all electrochemically associated. In particular, the extract of unfermented Camellia tea (i.e., green tea) was the most promising ESs to augment bioenergy extraction compared to other refreshing medicinal herb extracts. Due to abundance of polyphenolics, antioxidant potency of Camellia tea extracts directly determined their redox mediating characteristics to bioenergy recycling.

Topic: A New Method for Harvesting Natural Gas from Seabed Hydrates
Abstract: The gas hydrate deposits at seabed fall into a special category of gas hydrate resources. This study investigated technical feasibility of harvesting natural gas from seabed hydrates using a thermal method called Moving Riser Method (MRM). A mathematical model for heat transfer along the hose assembly in the MRM system was developed. Heat transfer from the injected hot water to the gas hydrate deposit was analyzed. The study concludes that with today’s pipe insulation technology water temperature drops only a few degrees from sea surface level to the seafloor level of 800m deep along an insulated vertical pipe. The injected water at seafloor level will be hot enough to dissociate gas hydrate. Gas production at commercial rate is achievable with affordable gas consumption rates to generate hot water. The level of gas production rate is proportional to the rate at which natural gas is combusted for hot water generation. The gas production to gas combustion ratio (PCR) is greater than 4. The PCR increases slightly with gas combustion rate. Even the gas production ship stays at the same location for over 40 hours, the water-hydrate boundary will still be within 0.9 meter of the hot water injection point. Therefore it is possible to use a gas collector of reasonable size (e.g., 2m in diameter) to gather all dissociate gas from the hydrate deposit. Result of this investigation shows that harvesting natural gas from gas hydrate at seabed with the MRM is technically viable, economically feasible, and environmentally safe.
