Zip fuel is a chemical jet fuel from the cold war days containing various hydrogen-boron compounds, or boranes. The full details have never been released.
Zip fuels offered higher power than conventional jet fuel, up to double on a thrust per unit weight basis - possibly more if the full truth were known - but boranes are toxic and the fuel could only used in the afterburners - so the jet would need two fuels and the afterburners could not be used on takeoff if there was a ground crew within a large radius. If there was any remnant of radioactivity when burned, it was never mentioned in the literature AKAIK. However, if any hydrinos were being formed during the violent combustion process, one might expect that some tiny remnant of radiation activation would have occured, even if most of it never interacted with the aircraft structure. Alternatively, if a deuterated zip fuel were burned, and there was any deuteron "stripping" the afterburners would have indicated larger degrees of activation. But there is no record of that nor of anyone ever suggesting it. A number of aircraft were designed to make use of zip, including the XB-70 Valkyrie, XF-108 Rapier, as well as the BOMARC missile, and even in the nuclear powered aircraft program (ANP) where there were additional advantages of zip due to boron's high cross-section for neutrons - which would have made it an incredible fuel with a neutron source. It has been claimed that the "Blackstar spaceplane" and/or Blackswift uses zip fuel, and that such a fuel exists today - but Blackstar is almost certainly mythical, at least according to "what they want us to know" i.e. Wiki, and I should never even mentioned this detail in mixed company... so to speak. http://en.wikipedia.org/wiki/Blackstar_(spaceplane) A relic of the zip fuel days - not to mention the "twenty mule team" is an abandoned dirt airfield outside Boron, Ca. near Death Valley and marked on maps as "Air Force Plant #72". It can be speculated that this would have been a factory for making zip fuel, using the large borax deposits nearby (giving the town its name), and proximity to Edwards Air Force Base - had the program not been cancelled. This abandoned place, and the lack of anything else in the literature, makes me think that zip fuel died a natural death in the sixties. Maybe the "zip-fuel saga", if there is to ultimately to be found to be a hydrino connection, falls in the category of "missed opportunity" ... and/or maybe Robin, like myself, occasionally gets this kind of information, ostensibly with high bogosity potential <g> from an "alternative reality" aka parallel universe...
