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.”

So does the Earth.

No, it doesn't.

Your link only talks about one side of the energy budget. The whole equation takes the energy coming in from Sol into account.

In fact, your own link says, "Despite its geological significance, this heat energy coming from Earth's interior is actually only 0.03% of Earth's total energy budget at the surface, which is dominated by 173,000 TW of incoming solar radiation."

47 TW is less of a considerable amount than 173 PW.

The focus on the very rich is really a focus on people with a vested interest in preserving the status quo. People who have been, or feel like they have been, screwed over by "the system" are less likely to be well behaved cogs in that same system. Also, people who think that they've outsmarted the system by sloughing off their debts are less likely to think that the system is working for them and their interests. It's less about circumstances and more about the mindset of potential recruits.

To elaborate, even (especially?) in the countries where the US government has a direct impact on foreign citizens' lives (drone strikes, etc), the local government kills/imprisons more of its own citizens under questionable circumstances than the US does.

Don't construe my comment as excusing or apologizing for the actions of the US government abroad. I'm only saying that your own government is more of a threat to your life and liberty than any foreign government, if only because of its proximity to you. History certainly bears this out. Don't let an irrational fear of the American bogeyman drive you, with blind trust, into the arms of the devil you know.

The only tangible (and verifiable) difference between Dropbox and SpiderOak is marketing. If, tomorrow, Google or Facebook started making the same security claims that SpiderOak makes now, would you trust them? Don't be so quick to trust unsubstantiated claims just because they're marketed toward your specific hopes and desires.

Out of curiosity, why do you feel this way?

Personally, I'd rather not be spied on at all. But if anyone were to spy on me, I'd prefer it be a foreign government who can't directly affect my life or freedom. Do you really trust your own government so implicitly? What do you think the Americans are going to do to you?

monolithic: (of an organization or system) large, powerful (sic), and intractably indivisible and uniform.

Being composed of different absolutely interdependent binaries is functionally indistinguishable from being a single binary composed of absolutely interdependent functions. It's the intractably indivisibility that makes it monolithic. You can't, for example, use this VT replacement without the rest of systemd. Thus, it's monolithic.

Monolithic (in this case) is the description of an architecture.

We have the lowest concentration of blue sensitive photoreceptors in the fovea centralis, so reading blue lights (or things lit with blue light) is relatively difficult. Indeed, the localization of blue point sources is difficult, making bright blue LEDs look hazy and indistinct even while being blinding.

I can't wait for this trend to end either. I hope my green VFD and LCD alarm clocks hold out. So soothing and easily readable.

Amazon's appstore runs with the same level of privilege as F-Droid. If you allow it to, it will check for updates to your apps (just like F-Droid), but it can't install apps without your permission. Google's core apps all run as root and have complete access to your data.

Amazon's a sleazy dataminer, too, but their appstore on Android is nothing like Google Play in its ability to be creepy and invasive.

And there is a standard instrument for someone or organisation writing an opinion on a political issue, and then seeking a mass of others to endorse it. It's called a petition.

Standardized by who, exactly? It's clear from the identical letters what is a form letter and what is an individually crafted letter. There's nothing fraudulent about form letters, even if they are lazy and tasteless.

35,000 Walrus Come Ashore In Alaska 292

the eric conspiracy writes "Lack of sea ice in the Arctic has forced record numbers of walrus to come ashore in Alaska. The walrus, looking for a place to rest have come ashore in Point Lay Alaska. The walrus normally rest on floating ice. "We are witnessing a slow-motion catastrophe in the Arctic," Lou Leonard, vice president for climate change at the World Wildlife Fund, said in a statement that was reported by CNN. "As this ice dwindles, the Arctic will experience some of the most dramatic changes our generation has ever witnessed. This loss will impact the annual migration of wildlife through the region, threaten the long-term health of walrus and polar bear populations, and change the lives of those who rely on the Arctic ecosystem for their way of life."

Smokeless gunpowder isn't a mixture of powders, though. It's (mostly) nitrocellulose. To make a consistent product, you'll need a consistent stock of cellulose (paper, cotton, etc), a consistent stock of nitric and sulfuric acid, and a consistent process of carrying out the reaction and cutting/flaking the product. It's not a difficult process, but it's more involved than making black powder (which is not worth going back to) and consistency is key.

Making primers, which are primary explosives by necessity, is not something that a sane amateur would do in his garage. I'm a chemist and even I don't want to fuck with making primers.

Yeah, the rule is generally that the speed of any given car moving on a road will be inversely related to the speed that the car is capable of achieving. The exceptions appear to be the WRX and the Prius.

If you're pulling up to a stop light and want to know which lane will move faster once the light turns green, pick the lane with the rusty old minivans and econoboxes over the one with the sportscars.
