Stimulated Gamma Decay Weapons
ExRex writes "New Scientist is reporting on a USDOD project to produce super explosives. 'An exotic kind of nuclear explosive being developed by the US Department of Defense could blur the critical distinction between conventional and nuclear weapons. The work has also raised fears that weapons based on this technology could trigger the next arms race.'"
My basic question concerning this is two-fold, is this realy needed, and if it is created will we be able to control the techology. With world events the way they are now it seems like one of the last things that we end is a small high yeild weapon that can fall into the worng hands. At least with nuclear weapons there are some means of detecting their presence, but it seems that these weapons will not have the same signature.
If 1g hafnium > 50 kg TNT, wouldn't this make an excellent fuel for a spacecraft's propulsion system? How does the energy density stack up against conventional/current experimental rocket systems? As I understand it one of the difficulties in sending a probe to Pluto is not getting there, but carrying sufficient fuel to be able to slow and enter orbit once it arrives.
My conspiracy theory is that Lawrence Livermore or Area 51 or some such government run hush hush spot may have a weapon based on this on the drawing board, or even in development. When the dudes published the idea in 2000, Lawrence livermore published fake negative results to keep the other countries of the world from working on the idea, and then secretly have been working on it ever since. Now that mini-nukes are back in style since 9/11, they can even say they're working on it in public and don't have to hide their research.
Eat at Joe's.
The apocryphal nuclear suitcase bomb notwithstanding, it is very difficult to make nuclear weapons small enough for tactical use. To save you from greater chance of carpal tunnel syndrome, I am aware of nuclear artillery shells, but they only fit the largest of howitzers. On the other hand, weapons based on this technology could conceivably be deployed at the squad level in a manner similar to an RPG or bazooka. It makes it much harder to control its use when deployed in such fashion. With standing armies of hundreds of thousands of soldiers the fallout from such a weapon used in combat would probably litter the countryside in a manner similar to land mines in such now forgotten conflicts (by most in the Western world) as the Namibian war for independence from South Africa.
To join in with the amoral, technophilic point of view preferred in this forum. From a technical point of view the problem with fallout seems to be related to the rate at which the halfnium explodes compared to the rate at which its volume is exposed to an x-ray source. Thus it seems that forming the halfnium in a thin shell around, and surrounded by, an x-ray source should mitigate fallout. However, I can't think to too many switchable x-ray sources other than a fission reaction which off course will cause its own problems...
Beyond the obvious Hulk jokes, did anyone follow the link in the articles? This story describes how this technology is slated to be used in powering UAVs that could stay aloft over a combat zone for months at a time. IMHO, channelling and controlling the energy in a useful way such as this is much cooler than being able to build a straight energy-release bomb.
