It’s said that the use of thorium in molten salt reactors would produce less toxic waste in the long run, and could be more easily reprocessed.‘This is a technology with much perspective for large scale energy production,’ said Sander de Groot, of NRG.‘We want to have a head-start once the technology will break through.
We see this as a commercial opportunity for the long-term.’The first experiment will build off the concept of the waste-burning MSR, or Molten Salt Fast Reactor.
When I presented this and similar criticisms of isotope dating to a gathering of the Lucas Heights Scientific Society (Sydney, Australia) in 1989, the only response that came from the chief of the division responsible for isotope dating at the Australian Nuclear Science and Technology Organization was the question, ‘Do you have a better dating method?
’ I said ‘No’, and he appeared to be satisfied that if there are no better methods of dating, then these are good enough.
In fact, the other 139 crystals show such a confusion of information that a statistician could only conclude that no sensible dates could be extracted from the data. They extracted diamonds from rocks in Zaire and found by the potassium-argon method that they (the diamonds) were six billion years old.A further problem is that the 4.3 billion-year-old zircon, dated according to the U/U method, was identified by the U/Th method to be undatable. But the earth is supposed to be only 4.5 billion years old. They admitted, however, that if the date had not been contradicted by the ‘known’ age of the earth, they would have accepted it as valid.An unbiased observer would be forced to admit that this contradiction prevents any conclusion as to the age of the crystal. This clearly shows two fundamental flaws in long-age isotope dating.China has also shown interest in MSR technology, with plans to have thorium-based reactors added to the grid within the next two decades.Sony SRS-XB40 has a built-in multi-coloured line light, speaker lights and a flashing strobe.
