Check out the latest leading edge technology ideas presented this week by winners of NASA Innovative Advanced Concepts (NIAC) Program grants at the 2018 NIAC Symposium underway in Boston till Thursday. The agenda (pdf) lists the talks and you can watch the presentations at the NIAC 2018 Livestream.
Below are videos of three of the sessions on Tuesday. The presenters included, for example, Ryan Weed of Positron Dynamics on antimatter catalyzed fusion propulsion, Stephanie Thomas of Princeton Satellite Systems on a plasma magnetic fusion propulsion design, and James Woodward of the Space Studies Institute on a Mach Effect drive.
This video from Princeton Satellite Systems describes their fusion propulsion design:
