Lois McMaster Bujold:
Heard about the EM Drive? Invention appears to defy classical mechanics by producing thrust from energy without using propellant, which violates conservation of momentum. NASA is testing and so far hasn't managed to disprove it - in other words, continues to validate the invention. Could lead to viable space travel. http://www.nasaspaceflight.com/2015/04/evaluating-nasas-futuristic-em-drive/

Hope it works out!
Indeed, I never pictured my own stories' ships moving through Nexus normal space using reaction mass of any kind. Gravitational rowing, for all I know, but not spitting stuff out the back end at high velocity. So many problems with the physics of that.
(Yes, I know "fuel" gets mentioned, because one can't get something for nothing, not to mention "thrusters", but one should not be picturing chemical combustants.)

I must say that the Vorkosigan saga is my favorite work of yours! I have reread the books so many times and the Civil Campaign is definitely the one I always recommend to my friends - it is amazing. I would like to ask whether you plan to write another book for the Vorkosigans or the lovely cousin Vorpatril? (and I really hope so). Thank you!
