All: I was reading a paper by H.D. Froning, which can be found at: http://www.unitelnw.com/fronin02.htm This paper mentions a relativistic propulsion system called a "quantum ramjet." Does anyone here have any idea what this is, and where I could obtain more information on this? Kyle R. Mcallister Email: stk@sunherald.infi.net Phone: 228-875-0629
