  1. Re:All you need to know, from TFA on Italian Scientists Demonstrate Cold Fusion? · · Score: 4, Insightful

    If it really works they could create a business out of it and retire.

    But if it really is nuclear something, I doubt they want to try to scale it up until they know what's really going on.

    The problem is the nickel metal hydride battery manufacturers have been screwing around with nickel and hydrogen for a long time on a very large scale without vaporizing the planet, so regardless of what is going on, scaling it up will probably be as harmless as a nearby battery plant.

  2. Re:Might not be fusion on Italian Scientists Demonstrate Cold Fusion? · · Score: 2

    They could have accidentally made a Nickel-Hydrogen battery. A remarkably efficient battery, which itself is pretty useful, but until they provide some concrete evidence that fusion is producing the majority of the power output here (e.g. a high fast-neutron flux), other methods of power production are more likely.

    Assuming the device actually works, of course.

    A better question, is why does their nickel-metal hydride "reactor" produce excess power that never showed up when the NiMH researchers did their rather extensive battery experiments in the past? News stories about batteries spontaneously combusting are mostly about lithium batteries not NiMH.

    Now if it was common knowledge that NiMH battery plants occasionally went nuclear, then maybe their experiment would have some merit, but...

    Note that fullerenes form in natural soot. So its unlikely a typical fullerene is super dangerous.

    One huge problem is fullerenes are a class of material, not one individual atom (err, well, they're mostly C) or molecule. You know how pissed off chemists were about that superman movie where he dissolved a computer using "acid" so a generation of the clueless masses grew up thinking there is an element or something called "acid" and all acids including citric will instantly vaporize steel, fiberglass, and silicon? Well the nano guys get that way about fullerenes and cancer. Could you theoretically micromachine a nanotube that is the exact same size and shape as an asbestos fiber and then inhale a bunch of them and die? Well, yeah if you intentionally tried really freaking hard, but why would you do something that stupid?

    Kind of like blaming that new-fangled "metal" technology because people get hurt when tiny chemically propelled chunks of "metal" strike them in their heart, or when you make a hundred pound pile of U235 bad stuff happens, so I suggest we all live in fear of this "metal" technology and watch lots of scary TV.

    For some reason, most advertisers in the US seem to instead focus on the lowest common denominator ....

    Average IQ of "tv watchers" is below 100 and dropping. There is a strong feedback loop where the intelligence level of shows (and advertisements) drops, so the average of viewers whom still watch tend to drop, leading to lower shows succeeding, leading to further drops, etc.

    Its an extremely strong feedback loop... regardless of trends in the greater population, with regards to the subpopulation of people whom still watch TV, we are rapidly approaching idiocracy / "ow my balls" level where that is all thats on, because no one watches except people low enough to find that insightful, and the advertisers whom cater to them.

    Effectively what they're doing is turning sunlight into chemical energy. The process sounds complex at first glance, so can it be more efficient than other methods of capturing solar energy? From a technical POV the percentage of sunlight captured is interesting. But from a business POV the costs are interesting, and I think overall more important: real estate footprint, amortized capital costs, and operational costs. Where do these fall relative to other methods?

    Well, best comparison model is probably farming, where your typical crop runs about 1 or 2 percent efficiency from sunlight to glucose but these guys can almost make methane at 15% efficiency. Also fertilizer and insecticide costs are zero and theoretically you can produce whenever the sun is up regardless of outdoor temperature.

    So I'm thinking it would be a bit more capital intensive and much less risky than industrial farming.
