Differential sail
Bad physics. Not notable. Can come back in the unlikely case it's not a complete fairy dream. --Pjacobi 16:02, 2005 May 4 (UTC) Then they were presented by this author on one NASA workshop and made it into one NASA press release.
 * Keep. Alleged "bad physics" is notable if it's pursued by brainstorming NASA physicists. Samaritan 16:34, 4 May 2005 (UTC)
 * I agree, that there is research in the NASA BPP program, which is only crazy, but nevertheless notable. But the four examples I've put on VfD, where originally published by one author:
 * Millis' "Challenge to Create the Space Drive," in the AIAA Journal of Propulsion and Power
 * Nothing more has been heard from this at NASA. No research was funded (nobody knows how to do any research in these directions). Check later NASA BPP publications, check with the NASA search engine, check their newest summary.

 * Delete. The Breakthrough Propulsion Physics Program is a NASA brainstorming project to come up with really off-the-wall types of engines.  Most of the stuff that comes out of it will be impossible, either for engineering reasons, or because the underlying physics were not sufficiently understood.  If there has been no followup research, then I don't think we need an article on it.  --Carnildo 20:04, 4 May 2005 (UTC)
 * Merge and redirect to Breakthrough Propulsion Physics Program. Rossami (talk) 00:06, 5 May 2005 (UTC)
 * Keep cleanup and expand. Notable. Megan1967 02:19, 5 May 2005 (UTC)
 * Keep, notable bad physics. Kappa 23:37, 5 May 2005 (UTC)
 * Keep as per Megan1967. —Markaci 2005-05-6 T 03:40 Z
 * Keep, per arguments by keepers above. &mdash;Lowellian (talk) 08:19, May 7, 2005 (UTC)
