Three-dimensional panel configurations to reduce wind load and increase passive convection cooling of photovoltaic surface on solar tracking systems

Edgar R., Cochard S., Stachurski Z., Australian National University, AU

For photovoltaic power systems there is a new class of three-dimensional panel arrangements better adapted to strong wind conditions than contiguous plates of equivalent frontal. These arrangements are unique in having overlapping layers of non-overlapping [...]

Dilute Methane Pollution Control That Produces Continuous Clean Renewable Energy

Blair J., Fukumoto P., FlexEnergy, US

Methane is a greenhouse gas that has 25 times the environmental impact of carbon dioxide. Millions of tons of manmade methane seep into the atmosphere each year. Controlling this methane has been problematic. Much of [...]

The Intersection Between Water Scarcity and Renewable Energy

Muys Jr. J.C., Karp J.M., Hildebrand Jr. V.P., Sullivan & Worcester LLP, US

The starting point for any discussion of the intersection between water scarcity and renewable energy is the now generally-accepted correlation between climate change and water resource impacts, which is creating further imperatives for both reduction [...]

Biogas Production from Co-Digestion of Horse Manure and Waste Sewage Sluge

Agayev E., Ugurlu A., Hacettepe University, TR

Biogas yield of horse manure was evaluated in batch and continous digesters. Studies were carried out in three stages. The biogas yields of horse manure in the batch studies after 35 days of the digestion [...]

Biomass Power Generation Using Liquid Tin Anode SOFC

Bentley J., Tao T., CellTech Power LLC, US

Currently biomass contributes only 1% of U.S. electric power despite available resources to provide over 20%. Barriers to increased use of biopower include low efficiency of current generators, high capital cost, low fuel energy, feedstock [...]

A Smarter Grid enables Communal MicroGrids

Mohn T., General MicroGrids, Inc, US

As policy makers seek to integrate a serious sociological and environmental issue into energy production, the typical utility is faced with not only technology upgrades, but also dealing with new systemic events that occur far [...]

High-Power-Density Miniscale Renewable Energy Systems

Lyshevski S.E., Rochester Institute of Technology, US

This paper reports design, analysis, evaluations and characterization of miniscale self-sustained power generation systems. Our ultimate objective is to guarantee highly-efficient mechanical-to-electrical energy conversion, ensure premier wind- or hydro- energy harvesting capabilities, enable electric machinery [...]
