According to a 2014 study commissioned by the Department of Energy, hydropower from more than 3 million untapped streams in the United States could potentially generate 65 gigawatts of electricity and help to reduce greenhouse emissions and pollution. However, the development of hydropower has been limited by several obstacles, as described by the United States Geological Survey: most of the prime ...

Supercritical CO2 cycles have the potential to significantly improve efficiency and reduce emissions in power generation. However, the unique fluid dynamic properties of supercritical CO2 that enable these higher efficiencies also complicate the design and layout of the system, particularly its turbomachinery components. The problem stems specifically from the highly non-linear properties of CO2, ...

Letters from leading researchers of subsurface hydrobiogeochemical processes, including Department of Energy researchers, confirm the need for low-cost, rugged distributed temperature sensing. Temperature and thermal gradients are critical drivers and state variables in many important subsurface hydrobiogeochemical processes, as well as indicators of hydrologic phenomena. In addition to helping un ...

Tactical Air Control Party (TACP) personnel juggle disparate tasks simultaneously. Their task simultaneously require physically grueling output, instantaneous information processing, clear communication and instantaneous decision-making. The current system provides capabilities far beyond their predecessors but with drawbacks: an information-rich battlefield requires increased time looking at ches ...

The proposed multi-spectral IFF beacon will use 40 to 50 % effient high power laser diodes at 863, 1064, and 1550 nm wavelengths. Thermal emitters including diamond-like carbon thin films, photonic crystals, and quantum cascade lasers will be characterized and compared. Finally a model to predict the detection range of IFF beacons will be developed using proprietary emitter power and atmospheric ...

Microbial contamination in kerosene based aviation fuels has been a problem for the USAF since the 1960’s. Antimicrobial effect of earlier used fuel system icing inhibitor (FSII) became an initial solution to this problem, but later, such fuel additives were banned due to their extreme toxicity towards humans. Newer FSIIs, being more eco-friendly, do not possess the antimicrobial properties of ...

Biodiesel is our next generation eco

A major limiting factor to organic cell efficiency is exciton diffusion and charge transport, which depend on charge carrier mobility in the E-fields created internally by the device materials and structure. Versatilis proposes a novel approach to ultimately improving >10% the efficiencies realized by typical organic solar cells, whether

A major limiting factor to organic photovoltaic (OPV) solar cell efficiency is exciton diffusion and charge transport, which depend in turn on carrier mobility and the E-fields created internally by the device materials and structure. Versatilis proposes a novel approach to enabling the better OPV cells from leading OPV makers to reach >10% efficiencies, whether

Wind power has the potential of supplying a significant percentage of the United States electrical demand at low cost. However, costs of transportation, erection, and repair must be reduced before these systems are competitive with current technology. The large size of multi megawatt turbine components makes transportation from manufacturing facilities to wind sites problematic. Once on site, t ...
