ALEXANDRIA, VA, November 4, 2020—The Department of Defense’s (DoD) Strategic Environmental Research and Development Program (SERDP) is seeking to fund environmental research and development in the Resource Conservation and Resiliency program area. SERDP invests across the broad spectrum of basic and applied research, as well as advanced technology development. The development and application of innovative environmental technologies will reduce the costs, environmental risks, and time required to resolve environmental problems while, at the same time, enhancing and sustaining military readiness.(more…)

Every Administration makes changes to the draft budget they receive before it is submitted to Congress, and there’s every reason to expect that to be the case with a President Biden. The budget is supposed to be submitted by the first Monday in February, but that deadline is rarely met. Incoming Presidents Ronald Reagan, Bill Clinton, and George W. Bush submitted their budgets in April, while President Barack Obama submitted his first budget in May. In this window, changes get made to better reflect the priorities of the incoming Administration.(more…)
The U.S. Naval Research Laboratory (NRL) is developing technologies designed to capture solar power in space, directly by an orbiting satellite, and beaming that captured power back to Earth. One of those technologies is the Photovoltaic RF Antenna Module (PRAM) satellite launched in May 2020 aboard the U.S. Air Force’s experimental orbital aircraft, the X-37B. Power beaming uses different light frequencies to wirelessly transmit power to a receiver. NRL previously tested a land-based system using an infrared laser whose 400 watts of direct current was wirelessly captured by photovoltaic cells tuned to the laser’s wavelengths over a distance of 325 meters. The collected satellite data will be also be compared to existing data from the land-based experiment. (more…)
The deleterious effects of high temperatures and humidity on the performance of aircraft are exacerbated in many places around the world under climate change. Last year, in a Center for Climate and Security briefer, these effects were discussed for both rotary and fixed wing aircraft. They include reductions in take-off weight because of reduced lift and, longer take-off and landing distances. The result will be that military operations will be at higher risk of disruption or outright failure, particularly in those locations where longer over-water distances need to be traversed. Complementing the briefer is a recent study by Gratton et al. (2020) that collected and analyzed climate change effects on the operation of two types of commercial, civilian aircraft that are commonly used at Greek airports. (more…)
