Sandia Labs Harnesses the Sun’s Energy with Tiny Particles

Engineers at Sandia, along with part­ner institutions Georgia Tech, Bucknell University, King Saud University, and the German Aerospace Center (DLR), are using a falling-particle receiver to more efficiently convert solar energy to electri­city in large-scale, concentrating solar power (CSP) plants. Falling-particle receiver technology is attractive because it can cost-effectively capture and store heat at higher […]

Sandia Workers Received Entrepreneurial Spirit Awards

Jim Pacheco (now in the Active Response and Denial Dept.) received an Entrepreneurial Spirit Award for his participation in Sandia’s Entrepreneurial Separation to Transfer Technology (ESTT) program, which encourages researchers to take jobs at startup or expanding businesses. ESTT was started in 1994, and since then 144 Sandia employees have left the labs, 57 of […]

Pratt Whitney Rocketdyne Testing

On November 24, 2012 the National Solar Thermal Test Facility (NSTTF) began testing of the Pratt Whitney Rocketdyne (PWR) solar receiver shroud.  Fifteen days of solar testing are scheduled for this testing.  The flux levels on the shroud range between 100 and 500 suns.  The work is sponsored by PWR in cooperation with the Department […]

National Solar Thermal Testing Facility Beam Profiling

On Thursday, June 7, we began beam profiling the NSTTF field heliostat beam.  Using the “Hot 80” heliostats aimed at a single aimpoint on a vertical target, the peak flux was 192 W/cm2.  Using the remaining 128 heliostats (the Cool 128) aimed at a single aimpoint on a vertical target, the peak flux was 152 […]
