Thu, 14 Aug 2003 Paging Dr Strangelove New Scientist this week is reporting that: 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. The explosive works by stimulating the release of energy from the nuclei of certain elements but does not involve nuclear fission or fusion. The energy, emitted as gamma radiation, is thousands of times greater than that from conventional chemical explosives. The technology has already been included in the Department of Defense's Militarily Critical Technologies List, which says: "Such extraordinary energy density has the potential to revolutionise all aspects of warfare." Scientists have known for many years that the nuclei of some elements, such as hafnium, can exist in a high-energy state, or nuclear isomer, that slowly decays to a low-energy state by emitting gamma rays. For example, hafnium-178m2, the excited, isomeric form of hafnium-178, has a half-life of 31 years. The possibility that this process could be explosive was discovered when Carl Collins and colleagues at the University of Texas at Dallas demonstrated that they could artificially trigger the decay of the hafnium isomer by bombarding it with low-energy X-rays (New Scientist print edition, 3 July 1999). The experiment released 60 times as much energy as was put in, and in theory a much greater energy release could be achieved. Well, yeah. Only, a couple of months ago this very same idea was being touted around as a power source for reconnaisance drones that could stay airborn for months at a time. However, Lawrence Livermore National Laboratories don't seem to think it'll work: LIVERMORE, Calif. -- Physicists from the Lawrence Livermore National Laboratory, in collaboration with scientists at Los Alamos and Argonne national laboratories, have new results that strongly contradict recent reports claiming an accelerated emission of gamma rays from the nuclear isomer 31-yr. hafnium-178, and the opportunity for a controlled release of energy. The triggering source in the original experiment was a dental X-ray machine. Using the Advanced Photon Source at Argonne, which has more than 100,000 times higher X-ray intensity than the dental X-ray machine used in the original experiment, and a sample of isomeric Hf-178 fabricated at Los Alamos, the team of physicists expected to see an enormous signal indicating a controlled release of energy stored in the long lived nuclear excited state. However, the scientists observed no such signal and established an upper limit consistent with nuclear science and orders of magnitude below previous reports. So what's going on here? The idea of using Hafnium isomers as an energy storage device has been knocking around for a few years now. There seem to be two possibilities: the physics works, or it doesn't. If it works, then the LLNL results (from tests carried out in 2001) take some explaining -- how did a major research lab get it wrong? But if it doesn't work, why on earth is this wonder-weapon being touted around by the US Department of Defense, years after the LLNL research poured cold water over it? What bureaucratic agenda could be furthered by pursuing research (with extensive funding) into a technology that isn't compatible with physics as we currently understand it and that appears to be unworkable? I wonder where the money trail leads, and if it is only money that's at issue. After all, if you promise a politician a magic wand to solve military problems emerging tomorrow, they may be tempted to pay less attention to avoiding such problems today ...

Like this guy: Lizard-like aliens descended upon ancient Mayans and interbred with them, producing "a form of life they could inhabit, they fluctuated between a human and iguana appearance through chameleon-like abilities." Edgar Allen Poe, according to an article in New Federalist, was a counter-intelligence operative serving the U.S. government in the first half of the 1800s. Thus, Poe's stories possibly hint at an insider's knowledge of events. From what vision-world did H.P. Lovecraft perceive and write about "the Great Old Ones who lived ages before there were any men... They had shape but that shape was not made of matter... the Great Old Ones spoke to (the first men) by molding their dreams; for only thus could Their language reach the fleshy minds of mammals... (One day, the Great Old Ones would appear openly.) The time would be easy to know, for then mankind would have become as the Great Old Ones, free and wild and beyond good and evil, with laws and morals thrown aside and all men shouting and killing and reveling in joy. Then the liberated Old Ones would teach them new ways to shout and kill and revel and enjoy themselves..." Er, yes. Well.
