I want to welcome David Mathes to The Workshop, I appreciate that you are here! David has interest in multiple areas of propulsion and science including inertial, gravitic and electrostatic... Truly "Universal Propulsion"!!! David, feel free to look around, comment, post, or just "hang out"! Note: My apologies for the delay! Not sure what happened to my welcome post, I intended for it to be posted here a couple of days ago...
