The Fallout of a Helium-3 Crisis : Discovery News - 3 views

shared by Luís F. Simões on 22 Feb 11 - No Cached
  • So short in fact, that last year when the looming crisis, which reporters had been covering for years, became official, the price of helium-3 went from $150 per liter to $5,000 per liter.
  • The science, medical and security uses for helium-3 are so diverse that the crisis banded together a hodge-podge of universities, hospitals and government departments to try and find workable alternatives and engineer ways to recycle the gas they do have.
  • Luís F. Simões on 22 Feb 11
     
    So, which shall it be? Are we going to increase the production of hydrogen bombs, or can we finally go back to the Moon (http://en.wikipedia.org/wiki/Helium-3#Extraterrestrial_supplies) ?
  • dejanpetkow on 23 Feb 11
     
    None of these. Either you recycle, or you take it from natural sources on Earth. Although most people don't know - there is plenty of natural He3 on Earth. It's just nonsens to use it for energy production (in fusion reactors) since the energy belance for getting the He3 from these source on Earth is just negative. Or you try to substitute He3.

    Dario - perhaps worth giving a look to be up-to-date... There's even an article "Improving Classical and Decentralized Differential Evolution with New Mutation Operator and Population Topologies". They quote our CEC paper, but not the ParCo.

    Don't know if you have full text access, so here goes the quote: "Recently, Izzo et al. designed in [27] a heterogeneous asynchronous island model for DE. They considered five islands and five DE strategies (DE/best/1/exp, DE/rand/1/exp, DE/rand-to-best/1/exp, DE/best/2/exp, and DE/rand/2/exp), and studied five distributed DEs using the same DE strategy in all the islands, and a heterogeneous model with one different DE strategy in every island. As a result, the heterogeneous model is not outstanding, but performs as well as the others."
  • Joris _ on 03 Mar 11
     
    Isn't it a bit a paper-killing quote?
  • Ma Ru on 03 Mar 11
     
    :) It's in the context of a review of the work that's been done about DE with island model in general, they don't evaluate. Pity they didn't refer to the ParCo article on topologies, as it was a bit more extensive and more focused on the method (as they do in the article) rather than on the problem (as was our CEC paper, if I recall well).

    As I now work in the Centre for Robotics *and Neuroscience*, here's a story for you. Some highlights: "It sent the iron straight up into his skull and out of the top of his head, landing some 30 metres away. (...) Phineas was unconscious before getting up and riding an oxcart into town with, 'a big bleedin' hole in his head'. (...) although Phineas survived, he was a changed man. Now he was reportedly unreliable, partial to swearing and often making inappropriate remarks." I guess If I were him I'd be a little partial to swearing too.

It's worse than stupidity: it's a marketing hype campaign [...] Somebody is saying this is inevitable - and whenever you hear somebody saying that, it's very likely to be a set of businesses campaigning to make it true."

    Watch out!! I read quite a lot about the contribution by EPFL (apparently coordinator) and their boss, Henry Markram. From what I read, this is not really science, but mainly a PR campaign. The main motor in this project is attracting a lot of money and the main aim to do so is promising a lot of stuff that nobody will be able to deliver. Accordingly, Markram is a very controversial person in the business...
  • Luzi Bergamin on 20 May 11
     
    Oups, sorry! Of course I meant, "the main MEAN to do so...", but the aim justifies the means. Well, that's exactly Markram's motto, I guess.
  • LeopoldS on 21 May 11
     
    interesting info indeed ... I though still think that the overall goal of this project, even if too ambitious for the time being is interesting, no?
  • Luzi Bergamin on 22 May 11
     
    It's not about interesting or not, it's about serious science or not. Also the goal of a fortune-teller is interesting, isn't it? Any description of a good science project is too ambitious, that's normal and not necessarily PR. But personally I think there is a certain limit where a science project becomes a bad SciFi thriller. This one here is a dime novel, I think. But the too ambitious is not the only point I became very doubtful. I have seen quite a number of scientists and engineers from different fields; what I read about the character and attitude of this guy just hints towards the worst case scenario. It's presumptive evidence, I know...
  • LeopoldS on 22 May 11
     
    that bad! wow ....
  • Luzi Bergamin on 22 May 11
     
    You know me, I'm the bullshitter... You remember Kurzweil and his Singularity-nonsense. In a way this was very similar. Though I think Kurzweil and Markram are very different characters (The Singularity essentially is a religion, I can't see anything like that in Markram's claims) they seem to share an important point: they are both complete nerds that apparently never spent a single thought on the limits of science (in its English meaning) in general nor of their particular research field in specific. One may find this excusable, I don't. But even then, they make claims that the nerdest nerd must know that they are completely unrealistic and thus I just have to assume that they claim their nonsense on purpose. The reason in Markram's case clearly seems to be money. But all this does not mean that these nerds cannot produce valuable results.
