Independent Researchers Test Rossi's Alleged Cold Fusion Device For 32 Days 986

WheezyJoe (1168567) writes The E-Cat (or "Energy Catalyzer") is an alleged cold fusion device that produces heat from a low-energy nuclear reaction where nickel and hydrogen fuse into copper. Previous reports have tended to suggest the technology is a hoax, and the inventor Andrea Rossi's reluctance to share details of the device haven't helped the situation. ExtremeTech now reports that "six (reputable) researchers from Italy and Sweden" have "observed a small E-Cat over 32 days, where it produced net energy of 1.5 megawatt-hours, "far more than can be obtained from any known chemical sources in the small reactor volume."... "The researchers, analyzing the fuel before and after the 32-day burn, note that there is an isotope shift from a "natural" mix of Nickel-58/Nickel-60 to almost entirely Nickel-62 — a reaction that, the researchers say, cannot occur without nuclear reactions (i.e. fusion)." The paper (PDF) linked in the article concludes that the E-cat is "a device giving heat energy compatible with nuclear transformations, but it operates at low energy and gives neither nuclear radioactive waste nor emits radiation. From basic general knowledge in nuclear physics this should not be possible. Nevertheless we have to relate to the fact that the experimental results from our test show heat production beyond chemical burning, and that the E-Cat fuel undergoes nuclear transformations. It is certainly most unsatisfying that these results so far have no convincing theoretical explanation, but the experimental results cannot be dismissed or ignored just because of lack of theoretical understanding. Moreover, the E-Cat results are too conspicuous not to be followed up in detail. In addition, if proven sustainable in further tests the E-Cat invention has a large potential to become an important energy source." The observers understandably hedge a bit, though: The researchers are very careful about not actually saying that cold fusion/LENR is the source of the E-Cat’s energy, instead merely saying that an “unknown reaction” is at work. In serious scientific circles, LENR is still a bit of a joke/taboo topic. The paper is actually somewhat comical in this regard: The researchers really try to work out how the E-Cat produces so much darn energy — and they conclude that fusion is the only answer — but then they reel it all back in by adding: “The reaction speculation above should only be considered as an example of reasoning and not a serious conjecture.”

We have the same in Europe. At least one health care worker here has been infected and will probably die because someone thought it's smart to bring people infected with a 90% lethality virus home for treatment. Good job.

From March till now, the mortality rate for ebola infected Government and NGO workers has been around 55%.

It's higher for the the rest of the infected, as they usually have preexisting medical problems which renders them less able to fight the virus.

There was a piece on NPR a few days ago that said that the Doctors Without Borders people use a buddy system like this - and despite having hundreds of people on the ground in Africa for a month or more, have only had three staff infections.

I heard that too, so I went looking for more information.

October 04, 2014: Since March 2014, 16 MSF staff members contracted the virus; nine of them have died.

The "three" that NPR reported is probably Doctors Without Borders international staff, with the other infections being local staff.

Cost is about $15 billion. If there was real confidence it would work, the private sector would fund it.

What I think is telling is that at $15B you could have something like 5 GW sized fission plants. Even many research reactors have provisions to use utilize it's heat to produce electricity. Yet for all that money there are not only no provisions to produce electricity using ITER, but no provisions to even be able to install components to produce electricity.

Conveniently these "alternative trial designs" are not detailed in any way. Doing something different for the sake of doing something different is rarely a good idea.

The alternative I've repeatedly seen mentioned is the stepped wedge trial.

Basically, you take your sample, create subgroups of random patients, then give the treatment to one group at a time.

This allows you to use the upcoming subgroups as controls, while avoiding the ethical problems of denying people treatment.

The ethics are something reasonable people can and do disagree about. The problem in this particular situation is that you're trying to run a clinical trial during an active pandemic against a disease with a high mortality rate. And, IMHO, those facts tip the ethical scales quiet heavily in favor of giving everyone experimental drugs that aren't known to be actively harmful.

Am I the only one that is still wondering why these "snowden leaks" are still coming out in the way that they are?

Yes.

The rest of us remember the wikileaks document dump and how important stories got did not get appropriate attention because of the sheer volume that was getting reported at once.

Another (perhaps unintended) aspect of the continuous reporting is that almost every time a denial is issued, the NSA is subsequently revealed as lying to the public and Congress.

37 meters. In some single-story houses, you will be able to make it. But let's not forget, that there is rarely a straight path for each drop back to the utility entrance.

You don't actually have to have all the drops go back to the entrance. I didn't mention it in this post(or I edited it out and don't remember doing it), but putting your switch in a central location can help drastically. Though I agree, 37 meters wouldn't be enough in many cases, the extra 18 meters I mentioned can make all the difference in the world for making that one run.

But note that I recommended both running the best wire available and conduit to boot. Futureproofing is a thing.

spanish flu killed 50-100 million people, because it infected 500 million and had a 10-20 % mortality rate.

you want enough people to survive to spread quickly, you want something that spreads like wildfire. Ebola isn't the easiest thing to spread, because it incapacitates the hell out of the carrier during their most infectious period, and it makes them pretty visibly infectious. And the mortality rate on ebola is too high to be scary.
