More Efficient Fuel Cells under Development by Engineers

Solar power and other sources of renewable energy can help combat global warming but they have a draw­back: they don’t produce energy as predictably as generating plants powered by oil, coal, or natural gas. Solar panels only produce electricity when the sun is shining, and wind turbines are only productive when the wind is brisk. […]

High-Efficiency Solar Thermochemical Reactor for Hydrogen Production

On June 16th, the Department of Energy Fuel Cell Technology Office (FCTO) announced $20 million for 10 R&D projects to advance technologies that can economically produce and deliver hydrogen to power fuel cells from diverse, domestic, and renewable resources thereby enabling substantial reductions in energy use and carbon emissions. Advancing these technologies is critical to […]

Sandian Re-Elected as President of the Association for Computing Machinery Special Interest Group on Graphics and Interactive Techniques

Jeff Jortner (in Sandia’s Scalable Modeling & Analysis Systems Dept.) has been re-elected for another three-year term as the President of the Association for Computing Machinery (ACM) Special Interest Group on Graphics and Interactive Techniques (SIGGRAPH). ACM is the world’s largest educational and scientific comput­ing society and delivers resources that advance computing as a science […]

Sandia Vertical-Axis Wind-Turbine Research Presented at Science of Making Torque from Wind Conference

In June, Brian Owens (in Sandia’s Analytical Structural Dynamics Dept.) and Todd Griffith (in Sandia’s Water Power Technologies Dept.) traveled to DTU Lyngby (Technical University of Denmark: Copenhagen, Denmark) to present Sandia research on deep-water multiple-megawatt vertical-axis wind turbines (VAWTs). High tip-speed ratios, low frequency structural vibration modes, and flexible blades of multiple-megawatt VAWTs can […]

Novel Nanoparticle Production Method Could Lead to Better Lights, Lenses, Solar Cells

Titanium-dioxide (TiO2) nanoparticles show great promise as fillers to tune the refractive index of anti-reflective coatings on signs and optical encapsulants (protective coverings or coatings) for light-emitting di­odes (LEDs), solar cells and other optical devices. Industry has shunned TiO2 nanoparticles because they have been difficult and expensive to make, and current methods produce particles that are too […]
