One issue that tends to support the thought that the internal energy can vanish without a visible trace is that the man onboard the ship can detect that he is undergoing acceleration while the drive is active. If it is eventually confirmed that a force arises from the activation of the drive then energy will be imparted onto the ship according to his measurements. Even though all velocities are considered relative, a change in velocity can usually be determined. That is reason to sustain hope for reactionless drives becoming a reality. It remains to be proven that the force obtained will be practical. So far there is reason to suspect that it does not exit at all.

And those particles that are produced are then given the momentum required to balance out that obtained by the ship. Also, they must remain in existence as real particles and not disappear after a brief time interval. The folks who speak of reactionless drives claim that their are no measurable particles remaining to locate after the momentum is imparted into the ship. That is where I can not agree. > >Dave Perhaps, because they are only virtual particles, they are still connected to the ZPF, and hence are effectively infinitely massive. That would mean that the energy imparted to the particles would approach zero, while still allowing transfer of momentum. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
