The electrochemical ultracapacitor is an emerging technology that promises to play an important role in meeting the demands of electronic devices and systems both now and in the future. This newly available technology of ultracapacitors is making it easier for engineers to balance their use of both energy and power. Energy storage devices like ultracapacitors are normally used along with batteries to compensate for the limited battery power capability. Evidently, the proper control of the energy storage systems presents both a challenge and opportunity for the power and energy management system. This paper traces the history of the development of the technology and explores the principles and theory of operation of the ultracapacitors.Go to page
It would differ from current solar collection methods in that the means used to collect energy would reside on an orbiting satellite instead of on Earth's surface. Some projected benefits of such a system are:
Higher collection rate: In space, transmission of solar energy is unaffected by the filtering effects of atmospheric gases. Consequently, collection in orbit is approximately 144% of the maximum attainable on Earth's surface. Longer collection period: Orbiting satellites can be exposed to a consistently high degree of solar radiation, generally for 24 hours per day, whereas surface panels can collect for 12 hours per day at most. Elimination of weather concerns, since the collecting satellite would reside well outside of any atmospheric gasses, cloud cover, wind, and other weather events.
Elimination of plant and wildlife interference.
Redirectable power transmission: A collecting satellite could possibly direct power on demand to different surface locations based on geographical baseload or peak load power needs.Go to page
