Pulsed plasmoid electric propulsion

A method of electric propulsion is explored where plasmoids such as spheromaks and field reversed configurations (FRC) are formed and then allowed to expand down a diverging conducting shell. The plasmoids contain a toroidal electric current that provides both heating and a confining magnetic field. They are free to translate because there are no externally supplied magnetic fields that would restrict motion. Image currents in the diverging conducting shell keep the plasmoids from contacting the wall. Because these currents translate relative to the wall, losses due to magnetic flux diffusion into the wall are minimized. During the expansion of the plasma in the diverging cone, both the inductive and thermal plasma energy are converted to directed kinetic energy producing thrust. Specific impulses can be in the 4000 to 20000 sec range with thrusts from 0.1 to 1000 Newtons, depending on available power

Is There Room for a Student of Rhetoric in a Giant NSF Grant Project?

Responding to recent movements exploring praxis possibilities for rhetoric of science scholars, my presentation shows one potential way for a student of rhetoric to be situated in a large science grant project and laboratory. This essay explores the promising benefits for rhetoric of science scholarship and grant project administration

Creative Engagements: Community Management Roles for RSTEM Praxis

Established roles for praxis beyond teaching are often missing from discussions of RSTEM engagement with the science community. Although it is important to ground engagement in identifiable roles, it may be that these roles are still being conceived or need to be re-created contextually for every engagement situation. This paper grounds RSTEM engagement in one identifiable field of practice: scientific community management. RSTEM\u27s specialized attention to and understanding of how science communities and genre systems interact can provide insight into the forming of these communities and their management
