    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.

    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.

    any idea if what the canadians claim to sell is closer to a quantum computer than what they did 2011? (I remember Luzi's comment back then that this had nothing to do with a quantum computer) Canada being member state of ESA ... should we start getting interested?

  • That raises another interesting question: how quickly could life-bearing ejecta from Earth (or anywhere else) seed the entire galaxy? Hara and co calculate that it would take some 10^12 years for ejecta to spread through a volume of space the size of the Milky Way. But since our galaxy is only 10^10 years old, a single ejection event could not have done the trick. However, they say that if life evolved at 25 different sites in the galaxy 10^10 years ago, then the combined ejecta from these places would now fill the Milky Way.

    what are seismic metamaterials?
  • LeopoldS on 21 Feb 12
     
    must look funny ... They calculate the properties of such a metatmaterial and how it might be constructed with a basic repeating unit in the form of a concrete cylinder some 18 metres in diameter, with four perpendicular holes in its sides (see picture). These cylinders, perhaps varying in size to absorb a range of seismic wavelengths, would need to surround the foundations of a building in cylindrical shells some 60 metres across. That needn't be prohibitively expensive but it would be a big structure that could only be constructed around isolated buildings (thereby somewhat negating the supposed benefit that other buildings in the earthquake 'shadow' might also be protected).

    Indeed, you only need ONE antenna to communicate with your satellite irrespective of its position, since one can freely send the signals right through the Earth. Small disadvantage: you should tell the launcher section to design a new launcher that is capable to bring a 200tons detector to space...

    A new blob-like robot described in the journal Advanced Robotics uses springs, feet, "protoplasm" and a distributed nervous system to move in a manner inspired by the slime mold Physarum polycepharum. Watch it ooze across a flat surface, The Blob style: Skip to 1:00 if you just want to be creeped out by its life-like quivering.
