Ion acoustic waves in the plasma with the power-law q-distribution in nonextensive statistics

We investigate the dispersion relation and Landau damping of ion acoustic waves in the collisionless magnetic-field-free plasma if it is described by the nonextensive q-distributions of Tsallis statistics. We show that the increased numbers of superthermal particles and low velocity particles can explain the strengthened and weakened modes of Landau damping, respectively, with the q-distribution. When the ion temperature is equal to the electron temperature, the weakly damped waves are found to be the distributions with small values of q.Comment: 9 pages,22 reference

Space Solar Power for Disaster Relief

Solar Powered satellites will have a future as an aid in disaster relief. These new satellites will not only be useful in gathering sun’s energy from space and transmitting it to Earth as electrical power, it can be expected that they will also be used in restoring communication and providing remote sensing as well as illumination. The recovery from disaster events is a timely stand-by service needed by all societies. In a collaborative effort of spacefaring nations and their partners, the launch of constellations of satellites that circle the globe will make rescue team response to saving lives quicker and more effective. This idea was brought forth by Dean Davis, Aerospace Scientist/Engineer, Lockheed Martin. This visualization, a space-based solar power design project of students at Ohio University, was presented and critiqued at the May 2011 International Space Development Conference in Huntsville, Alabama USA.
