The Microgrid Design Toolkit

Featured Opportunity • Sandia's Microgrid Design Toolkit (MDT) is a decision support software toolkit that aids designers in creating optimal microgrids. Microgrids are localized energy grids that provide flexibility through their ability to operate independently from the bulk power grid. Well-designed microgrids support resiliency, security, efficiency, local control, and increased access to renewable...

The Sandia Cooler

Featured Opportunity • Sandia researchers have developed a radically new architecture for air-cooled heat exchangers In conventional “fan-plus-finned-heat-sink” air-cooled heat exchangers, the primary physical limitation to performance (i.e. achieving low thermal resistance) is the boundary layer of motionless air that adheres to and envelops all surfaces of the heat exchanger. Within this boundary...

The Sandia Wave Reflector

Featured Opportunity • The Sandia wave reflector is a magnetic conductor for wireless transmissions near 433 MHz. The device reflects perpendicular electromagnetic waves in-phase and suppresses surface waves resulting in improved gain performance and effective operation regardless of physical placement. The reflector achieves gain improvement through a quarter-wave short phenomenon. The height of...

Thermal emitter comprising near-zero permittivity materials

Patent • #9,799,798. A novel thermal source comprising a semiconductor hyperbolic metamaterial provides control of the emission spectrum and the angular emission pattern. These properties arise because of epsilon-near-zero conditions in the semiconductor hyperbolic metamaterial. In particular, the thermal emission is dominated by the epsilon-near-zero effect in the doped quantum wells composing...
