A New Computational Model for Fluid-Structure Interaction Phenomena in Wind-Turbine Blades

Ponta F.L., Otero A.D., Lago L.I., Michigan Technological University, US

Limitations in the current blade technology constitute a technological barrier that needs to be broken in order to continue the improvement in wind-energy cost. Blade manufacturing is mostly based on composite laminates, which is labor-intensive [...]

Large Scale Integration of Wind Power Generation

Moura P.S., Almeida A.T., University of Coimbra, PT

The 2001/77/CE European Commission Directive sets the target of 22% and 39% of gross electricity generation from renewables for the Europe and Portugal by 2010. To satisfy this target, it is planned the installation of [...]

Sustainable Energy Opportunities with the Geothermal Continuum

Thorsteinsson H., Augustine C., Anderson B.J., Moore M.C., von Rohr P.R., Tester J.W., Massachusetts Institute of Technology, US

The publication of “The Future of Geothermal Energy” in 2006, which resulted from a comprehensive assessment of US geothermal potential, brought renewed interest in Engineered Geothermal Systems (EGS) worldwide. The magnitude and accessibility of the [...]

Overview of Developments and Applications of Thermoelectrics Integrated with MEMS

Takahashi M., Omron Silicon Valley, US

We are faced with many energy and environmental problems such as the running out of fossil fuels, rapid increase in energy consumption by emerging-economy countries, global warming, etc. Against such a background, development of advanced [...]

An “Atmospherically Healthy” Recipe for Carbon-Neutral Fuels: A synthetic fuel made from sunlight, CO2, and water

Littau K., Palo Alto Research Center (Parc), US

Although carbon capture and storage has been proposed as an effective means of reducing greenhouse gas emissions, this is not a realistic solution for mobile emitters where the capture system would need to be carried [...]

Exergy Analysis Of Double Flash Geothermal Power Plant, SABALAN, IRAN

Nasrabady S.J., University of Iceland, IS

Abstract: Mt Sabalan is located at NW of Iran with geothermal field under development. The double flash cycle was selected as a power generation system. The obtained results show that the highest power output from [...]

The case for Vertical Axis wind turbines

Sankar T.C., Robert Morris University, US

The Case for Vertical Axis Wind Turbines ABSTRACT Extensive studies have shown that there is enough wind globally to satisfy much, or even most, of humanity’s energy requirements – if we could harvest it effectively [...]

Wind characteristics of Algeria

Himri S., Himri Y., Draoui B., Himri S., Himri Y., Electricity & Gas National Enterprise (Sonelgaz), DZ

The paper presents wind speed data analysis over a period of almost 10 years between 1977 and 1988 from three stations, namely Adrar, Timimoun and Tindouf The long-term mean wind speed at Adrar, Timimoun and [...]

Post-annealing effect of copper phthalocyanine on enhancing the performance of green organic light-emitting diode

Chen S.Z., Jou J.H., Tang F.S., Chiang P.H., Chang C.Y., National Tsing Hua University, TW

Post-annealing copper phthalocyanine (CuPc) can effectively improve the efficiency of a green organic light-emitting diode, consisting of indium tin oxide/CuPc/N,N’-bis-(1-naphthyl)- N,N’-diphenyl-1,10-biphenyl-4-4’-diamine/tris-8-hydroxy-quinoline aluminum/lithium fluoride /aluminum. By annealing the device at 120℃ for 1 hr, the power [...]

Solar-Electric Commuting Trike with Manual Pedaling

Mil’shtein S., Srinivasan B., UMass Lowell, US

With dwindling petroleum resources and concerns about global climate, it is imperative to find better suited modes of commute for the future. In the United States, studies have shown that 50% of the travel on [...]
