    Actually Sante and me just reviewed their paper. Although (some of) the scientists in the paper seem to have good track records their experimental techniques are by far not the best to determine the excess amount of energy produced. Even though their methods may introduce fairly large errors they would not be able to negate the cited power output - so they either are super-sloppy (i.e. they lie) or there is TRULY new physics involved... A big problem is that they are basically verifying somebody else's experiment - however because this guy is paranoid he does not tell them exactly what he did. In fact they went to his lab and used a setup that HE put together. All they do is do a measurement on it and it seems like they try to be thorough. There is quite a chance that the guy behind it all (Rossi) is setting them up - personally I would think >95%. However, the implications of this being new physics are so big that I think further research should be conducted.

    I just answered something very similar to Franco, except the conclusions: I don't think that there is a good reason for us or anybody else in ESA to get involved at this stage.
  • johannessimon81 on 24 May 13
     
    I agree - if this device would work it there would be other interest groups (like the energy sector) with a much more concrete stake in the technology.

    Let's all start up some crazy space companies together: harvest hydrogen on Jupiter, trap black holes as unlimited energy supplies, use high temperatures close to the sun to bake bread! Apparently it is really easy to do just about anything and Deep Space Industries is really good at it. Plus: in their video they show Mars One concepts while referring to ESA and NASA.

    I really wonder what they wanna mine out there? Is there such a high demand on... rocks?! And do they really think they can collect fuel somewhere?
  • Wiktor Piotrowski on 24 Jan 13
     
    Well they want to avoid having to send resources into space and rather make it all in space. The first mission is just to find possible asteroids worth mining and bring some asteroid rocks to Earth for analysis. In 2020 they want to start mining for precious metals (e.g. nickel), water and such.They also want to put up a 3D printer in space so that it would extract, separate and/or fuse asteroidal resources together and then print the needed structures already in space. And even though on earth it's just rocks, in space a tonne of them has an estimated value of 1 million dollars (as opposed to 4000 USD on Earth). Although I like the idea, I would put DSI in the same basket as those Mars One nutters 'cause it's not gonna happen.
  • johannessimon81 on 25 Jan 13
     
    I will get excited once they demonstrate they can put a random rock into their machine and out comes a bicycle (then the obvious next step is a space station).
  • Joris _ on 26 Jan 13
     
    hmm aside from the technological feasibility, their approach still should be taken as an example, and deserve a little support. By tackling such difficult problems, they will devise innovative stuffs. Plus, even if this doom-to-fail endeavour may still seem you useless, it creates jobs and make people think... it is already a positive! Final word: how is that different from what Planetary Resources plan to do? It is founded by a bunch of so-called "nuts" ... (http://www.planetaryresources.com/team/) ! a little thought: "We must never be afraid to go too far, for success lies just beyond" - Proust
  • johannessimon81 on 28 Jan 13
     
    I don't think that this proposal is very different from the one by Planetary Resources. My scepticism is rooted in the fact that - at least to my knowledge - fully autonomous mining technology has not even been demonstrated on Earth. I am sure that their proposition is in principle (technically) feasible but at the same time I do not believe that a privately funded company will find enough people to finance a multi-billion dollar R&D project that may or may not lead to an economically sensible outcome, i.e. generate profit (not income - you have to pay back the R&D cost first) within the next 25 years. And on that timescale anything can happen - for all we know we will all be slaves to the singularity by the time they start mining. I do think that people who tackle difficult problems deserve support - and lots of it. It seems however that up till now they have only tackled making a promotional video... About job creation (sorry for the sarcasm): if usefulness is not so important my proposal would be to give shovels to two people - person A digs a hole and person B fills up the same hole at the same time. The good thing about this is that you can increase the number of jobs created simply by handing out more shovels.

Meteorite Crashes In Russia, Panic Spreads (Updating) - 5 views

    Latest update: the European Space Agency says their experts "confirm there is no link between the meteor incidents in Russia and asteroid 2012DA14 flyby tonight". How did they find this? As they did not see this one coming, how could they come to that conclusion that early!
  • ...5 more comments...
  • johannessimon81 on 15 Feb 13
     
    As you can see from the videos of this meteorite it is coming in from an east to south-east direction (i.e. the direction of the sunrise, more or less). 2012DA14 is coming from due south as you can see here: http://www.wired.com/wiredscience/2013/02/how-to-watch-asteroid-2012-da14/ So the two objects seem to be coming from different directions - at least that would be my explanation.
  • Joris _ on 15 Feb 13
     
    My point is, that if you want to come to such a conclusion (that it is not rubble) you need to be able to construct back the orbits of both objects. 2012DA14 has been observed for one year only, but it is well enough. When the meteor has been observed for the first time, such that we knew its orbit? has it been observed before? if yes, why the impact has not been predicted?
  • johannessimon81 on 15 Feb 13
     
    If you can show that they come from different directions you know that they are not associated, even if you don't reconstruct their orbits.
  • Joris _ on 15 Feb 13
     
    I don't think so. If both objects were part of the same, they would be on different but intersecting orbits anyway, hence different directions. Anyway, I am not knowledgeable in atmospheric entry ... But, with so few information about the object, I am surprised they are 100% certain it is not related to DA14. I think science requires more cautions ... With only the direction they are 100% sure, while the probability of such event is itself extremely small, I am amazed... They can't even predict with 100% certainty where a space debris will fall... plus, nobody consider the object being part of a bigger one that broke up during early entry (which has not been observed) ... so many uncertainties and possible hypothesis... and i am not the only one :) http://www.infowars.com/russian-meteor-linked-to-da14-asteroid/
  • LeopoldS on 17 Feb 13
     
    was not that evident to me also but apparently with the right understanding it was quite clear; was amazed also how quickly NASA has published the likely trajectory of the russian object - have a look at it: quite evident that these are not coming from the same body
  • Joris _ on 17 Feb 13
     
    yes, now i get my 100% certainty with the reconstructed orbits nothing else (http://wiki.nasa.gov/cm/blog/Watch%20the%20Skies/posts/post_1361037562855.html) ... I still think that esa anouncemement was highly premature but with a high probability of being right...

    One more reason why we should be much more open about all these EO data we have .... The two citizen scientists, Kian Jek and Robert Gagliano, are listed as authors on the scientific paper recently published. I love this: the digital nature of these data make it far, far easier to analyze the science than it was in the past, and also easier to get the data out to people. Because of this, we have an explosive growth in these kinds of projects. Planet Hunters is great, but then so is Galaxy Zoo, Moon Mappers, Ice Hunters, and so many others. You can find several of these collected at the CosmoQuest website.

    "Two sets of [ ATV docking training for astronauts ] lessons are now available for the home user to try." And in case you wonder *where* in the earth are they available, the links are on the right-hand column (also known as ESA's scorn on usability). As usual for the material located there, I took me a few minutes to find them...

  • Ma Ru on 13 Apr 12
     
    Leo, I'm not iEnabled, so I can't help you with the app. Using other links you can try the PC version (so 20th-century-ish, I know), of course assuming you have somewhere one with Internet Explorer :-)

  • These are just a few of the dreams being chased at Google X, the clandestine lab where Google is tackling a list of 100 shoot-for-the-stars ideas. In interviews, a dozen people discussed the list; some work at the lab or elsewhere at Google, and some have been briefed on the project. But none would speak for attribution because Google is so secretive about the effort that many employees do not even know the lab exists.

    Sounds relevant. Does ESA need to have a position on this question?
  • Luís F. Simões on 15 Mar 14
     
    This was on Slashdot now, with a link to the paper. It quite an iteresting study actually. "The scenarios most closely reflecting the reality of our world today are found in the third group of experiments (see section 5.3), where we introduced economic stratification. Under such conditions, we find that collapse is difficult to avoid."
  • Thijs Versloot on 16 Mar 14
     
    Interesting, but is it new? In general, I would say that history has shown us that it is inevitable that civilisations get replaced by new concepts (much is published about this, read eg Fog of War by Jona Lendering on the struggles between civilisations in ancient history, which have remarkably similar issues as today, yet on a different scale of course). "While some members of society might raise the alarm that the system is moving towards an impending collapse and therefore advocate structural changes to society in order to avoid it, Elites and their supporters, who opposed making these changes, could point to the long sustainable trajectory 'so far' in support of doing nothing." I guess this bang on it, the ones that can change the system, are not benefitted by doing so, hence enrichment, depletion, short term gain remain and might even accelerate to compensate for the loss in the rest of the system.
