Power Supplies

Energy demands are increasing as consumer, industrial, and data communications markets require greater power distribution.

The design of the CubeSat required precision pointing of the thrust vector through the spacecraft center of gravity to minimize fuel usage for attitude correction. Because the center of gravity shifts over the course of the mission, a means of adjusting the thrust vector was needed....

New phase change material was developed that has electrical characteristics that behave differently than those of conventional materials. This new material provides a drastic reduction in power consumption for data recording in nonvolatile random access memory (RAM).

As the number of channels, or operative sites, increases in present and future ground special power (GSP) development efforts, the amount of hardware required to test development codes becomes substantially expensive. By simulating/emulating the hardware, code...

Some insect bodies have evolved the ability to repel water and oil, adhere to different surfaces, and eliminate light reflections. Scientists have been studying the physical mechanisms underlying these properties found in nature and mimicking them to design materials for use in everyday...

Both the aerospace and automotive industries depend increasingly on electrochemical energy storage. Reduction in mass, increase in energy, and increase in power can benefit both of these areas dramatically. Supercapacitors are currently under consideration for use in both...

Cornell University scientists have developed an oxygen-assisted aluminum/carbon dioxide power cell that uses electrochemical reactions to both sequester the carbon dioxide and produce electricity.
