  1. Re:$30m/5 years? on US Offers $30M For High-Risk Biofuel Research · · Score: 2

    Beta Emitters = No pesky neutrons, Gamma rays of alpha particles...

    Not quite correct: most gamma ray sources are in fact beta emitters that decay into excited states of the daughter nucleus, which then decays via gamma emission.

    There are exceptions: 35S, which you mention, decays entirely to the ground state of 35Cl.

    There are still problems, though: bremmstralung radiation from the stopping electrons, modest (126 day) lifetime and long biological half-life (~45 days). The average decay energy is only 49 keV (endpoint is 167 keV) so to generate a watt assuming 100% conversion efficiency you need 1/(49*1000*1.6e-19) ~ 1e14 decays per second, which is up there in the mega-curries.

    Keeping it out of the environment at current discharge limits (micro-curries per kg) would be impossible, and it tends to affect the lungs, which are particularly susceptible to radiation (about 10% of lung cancer from smoking is due to potassium-40 decay.)

    So on the whole I'd rather invest in algal biodeisel, which fulfils the relatively simple mandate of the funded research: providing feedstock for existing liquid hydrocarbon energy infrastructure.

    The British government had to realise that there were genuine grievances and what it called "terrorists" saw themselves as soldiers.

    The question is not "are their grievances?" but "how are they being addressed?" If they are being "addressed" by violence the cycle of killing will go on. If they are being "seen to be addressed" even if they don't fix the nominal underlying problems, peace has a good chance of breaking out.

    Humans never use violence as a rational means of persuasion, because it isn't. It is an attempt to engage various relatively simple stimulus-response systems that were useful as a means of social control when we lived in small troops tens or hundreds of thousands of years ago.

Science and art are great examples of how to turn that basic drive to something creative and useful, as opposed to the destructive and stupid uses it is often put to, like politics and war.

    To the humans actually involved in the search, it matters a great deal who's first, and expecting them to dedicate their lives to the discovery without that added impetus is asking for humans to be other than they actually are. Good luck with that. We demonstrably have a choice as to how we choose to compete. We do not have a choice as to whether or not we compete.

    Furthermore, there are obvious practical advantages to having multiple experiments. You may have noticed that humans sometimes make mistakes, and are sometimes not honest. Monocultures and monopolies give no protections against those all too common characteristics, and if you think some protection isn't needed you are, unfortunately, naive.

In the 13 colonies you could have negotiated greater independence--and secured for yourselves the rights of Englishmen--in less than a generation, if your short-sighted idiots hadn't insisted on war.

    In Europe, the mess in the '20's and '30's that made war seem like a good idea to the NAZIs was a product of the "Great War", a fact you fail to mention. NAZI-ism was no more effective than Sovietism, and would have moderated under its own inadequacies in a decade or so if left to itself, with a far lower body count than WWII produced.

If some hot-headed idiot with zero grasp of economic rationality had whipped up the Poles into a frenzy of violent opposition resulting in a bloody and prolonged rebellion that after millions of deaths resulted in a free Poland you would no-doubt be asking, "How else could this have happened?"

    One of the biggest lessons that the New Right took from the Post-Structuralist Left in the '90's was the role of language-creation in dominating the public discourse.

    The post-structuralists rightly observed that groups in power tend to dominate how language is used, but rather than making a case for more objective, empirically-oriented language they concluded from this that the meaning of words was pretty much completely up for grabs. Like Humpty-Dumpty, words were to mean only what the powerful meant them to mean, and the only question was "who is to be master."

    For some reason the Left thought this would be them, as the Old Right had a modium of objectivity about it.
