Abstract: Embodiments described herein relate to systems and methods of CO2 uptake. In one aspect, a method includes applying heat to a calciner to decompose a carbon-containing stream to a gas stream and a stream of a carbonation medium, the gas stream including CO2. The method further includes sequestering and/or utilizing the gas stream, feeding the stream of the carbonation medium to a carbonation station, contacting the carbonation medium with ambient air at the carbonation station, such that the carbonation medium adsorbs CO2 to form the carbon-containing stream, during the contacting, adding a water stream to the carbonation medium at intervals of about 30 minutes to about 72 hours, and feeding the carbon-containing stream to the calciner. In some embodiments, adding the water stream is via misting and/or spraying.

Abstract: A geolocation system and method uses a single platform for determining a Doppler measurement set of a targeted aircraft or signal of interest. The electronic warfare aircraft and the ejected aircraft expendables technology device determine the Doppler measurement set of the targeted aircraft or other signal of interest. The ejected aircraft expendables technology device is initially tuned to an expected frequency of the target of interest. Re-tuning may take place after an initial signal reading and computation has been performed by the electronic warfare aircraft.
