There is significant opportunity for energy efficiency improvements in the industrial and manufacturing sectors in the U.S., both from the production and consumption perspective. Higher energy density battery materials will play a role in both, through improved storage of electricity from renewable sources, the enabling of electric vehicles, and through the development of longer lasting, higher po ...

Ice crystals can form spontaneously from the freezing of water droplets at temperatures colder than -38

This SBIR/STTR project delivers an ultra-low power structural health monitoring (SHM) system that uses autonomous, wirelessly embedded sensors to monitor and assess structural integrity in wind turbine blades. EASE features impedance-based active SHM, which is highly sensitive to damage like cracks, delimitations, mass variations, fastener failures and stiffness changes. Blades are the only wind t ...

The proposed innovation is the replacement of existing test stand and parking lot fixtures with current SSL LED technology. The replacement fixtures will reduce energy consumption, generate less heat and provide maintenance free operation for over 50,000 hours. An explosion-proof fixture is capable of containing an internal combustion event without allowing flames or hot gasses to escape to the s ...

The cost of dewatering particles is inversely proportional to particle size. Costs dramatically increase as particle size approaches 10

Hydrogen produced today from coal, natural gas, or biomass must be separated and purified outside the reactors using pressure swing absorption (PSA), a process that requires significant additional space and energy. Placing hydrogen-permeable membranes inside the reactors themselves would allow hydrogen to diffuse out, thereby reducing the cost of hydrogen production. In this Phase I effort, Mainst ...

Small and micro-spacecrafts require the efficient, micro-propulsion systems. Chemical micro-propulsion is best suited for use as primary thrust, orbital insertion and attitude control because of its high energy density. When grouped into arrays for larger thrust applications, micro-propulsion devices provide high propulsive flexibility or can be used as igniters. The proposed effort will focus ...

This proposal offers to provide NASA with an automatic mesh generator for the simulation of aerodynamic flows using Reynolds-Averages Navier-Stokes (RANS) models. The tools will be capable of generating high-quality, highly-stretched (anisotropic) grids in boundary layer regions and transition smoothly to inviscid flow regions even in an adaptive context. The objective of the work is to offer a un ...

Solid State Drives (SSDs) are emerging as attractive alternatives to traditional HDDs due to there reduced power consumption and potential for increased performance. SSDs have the potential to improve the performance of both Checkpoint Restart (CPR) and the Metadata Server (MDS) for high performance File Systems, e.g., Lustre. However, the write performance of SSDs is relatively poor (compared to ...

Energy consumption is quickly becoming one of the primary bottlenecks of compute clusters and supercomputers. The DOE is a primary developer and consumer of these power hungry supercomputers, however smaller cluster machines are also widely used through other government agencies and industries. Yet, there are few power profiling tools that allow application developers transparent insight into the ...
