Phase-shift Plasma Turbine - Interplanetary Spaceflight

submitted by: MFerreiraJr
The Phase-shift Turbine consists of a set of concentric coils, axially rotated from each other, and feed by phased RF sources, producing radial and longitudinal sequences, which results in helical moving force, ionizing intake gas/particle/ion, generating continuous unidirectional thrust. It was designed in order to operate in atmospheric environments, mainly during takeoff, and in space to reuse exhaust gases from chemical rockets to booster the overall ISP, enhancing utilization of both...

'GlyphSea': A New Way to Visualize Vector Data

submitted by: btolo

Researchers at the San Diego Supercomputer Center (SDSC) and other organizations within the University of California, San Diego, have developed a novel way to encode and display vector data that clearly shows magnitude and direction. This new visualization technique may help seismologists to accurately analyze ground movements for an earthquake, measure magnetic turbulence in deep space, or allow medical researchers to study areas such as blood flow and nutrient absorption.
