SEFE, a solutions-driven sustainability company developing and deploying a promising solution to our world's energy problems, today provided important details on its Cubic Wire Detector, which represents an enhancement to the company's pending patent covering Collection of Atmospheric Ions.

The Cubic Wire Detector is categorized as a "continuation-in-part" application, adding a variation to SEFE's patent-pending application for Collection of Atmospheric Ions while claiming priority based on the original patent, which was filed with the U.S. Patent and Trademark Office on May 12, 2011. The variation employs an open-frame cubic box with alternating wires rather than parallel plates to collect atmospheric ions, and helps identify where the most abundant source of atmospheric charge is located.

The cubic wire geometry is more suited to the flight environment and is also able to capture directionality, depletion, and charge mobility measurements. The alternating wires are held at a high voltage and the ions that pass between the wires are accelerated by the high voltage and measured as a current. The system adds a secondary decay mode to measure the mobility of the charge in the atmosphere during the test.

"The Cubic Wire Detector provides an important variation of the ion categorization technology; this allows us to perform the testing essential to the development of the Harmony III product line," said Ryan Coulson, Lead Scientist for SEFE. "Understanding where the highest charge density lies is absolutely critical to Harmony III. The Cubic Detector improves our ability to study how atmospheric static charge is consumed and replenished."
