Interesting.

The book mentioned, One Second After, is a must read in my opinion. It will scare the pants off you too.

    While a nuclear weapon does indeed create an EMP, that is not the only way that it can be created. A large coil with a powerful enough magnet run through it fast enough can do the same thing.

    And yet: <br />1) The discussion was not about nuclear weapons, <br />2) It was about EMPs. <br />3) And, oh yeah, if ionizing radiation is going to fry your semiconductors, then you've got bigger problems than whether your solar cells will survive. <br /><br />Your style grows tiresome. The pattern repeats seemingly without end. You make an incorrect statement. I point out your error. You abandon the statement and come up with another incorrect (or irrelevant) statement. I demonstrate you are once again incorrect, or the statement is irrelevant. You abandon the statement and come up with yet another… You're like a blocked sewage pipe… just when you think you've got it cleared up, another load of crap bubbles back up. <br /><br />In short, you're wrong again, and again, and again. There's no defense for your errors, so you make none. I can appreciate that. It's better than someone who is wrong and insists they're right. But why the constant stream of additional error/irrelevance? Are you even making any effort to post correct/relevant information? (It seems not.) <br /><br />EMPs are actually pretty simple. The only reason that I'd need to learn more than I already know is if I wanted to build an EMP device and quantify its effect for design.

    Your lack of knowledge of how semiconductor circuits are created is amazing. Your lack of knowledge of physics is terrifying, but you sure are good at spewing out vitriol

    Your first sentence is gibberish (at best ambiguous, but more likely incorrect). Your second sentence is simply wrong. <br /><br />As for the second paragraph, did you miss the "Even a coil would be unaffected so long as the induced voltage is not great enough to span the air gap between the two leads or break down the insulation in the winding."? Or did you just not understand it? <br /><br />Maybe you have a better grasp of physics than you are displaying, but you apparently lack the ability to read and comprehend, write cogently or apply sufficient rigor when discussing physics. The standards at the U Texas physics department must be lower than I thought.

    The silicon cells can deal with EMP. It's the electronics that collects, controls, and distributes the power generated that are vulnerable. The good news is that shielding doesn't reduce the efficiency, but the bad news is that it does increase the system cost.

    Susanne's Rule of Bug-out locations: If you a considerably far and difficult distance from the hoardes at your front, with nothing worth getting to at your back, then the likelihood of them wandering up your way to try their hand at emulating steel targets is somewhat diminished...

    Actually, I hope it DOES work. <br /><br />To your last point: Hasn't someone already paid $10 million?

    Fleischman and Pons' experiments were difficult to reproduce, and some claimed they had reproduced it on a limited scale, but by that point, so many others had come out and said "these guys lied" that the typical media crap just stuck. <br /><br />And considering university research is based strongly on public opinion (take for instance the global warming crap today), nobody was going to get much funding for "cold fusion". <br /><br />Materials science is much better today, and nanoparticles and nano lattices are much more easy to come across. There's literally a couple dozen different groups all doing similar work on LENR or LANR. <br /><br />But like I said, we'll see. Nobody's paying the guy any money until they see a working unit, so what's the benefit to him to try to scam anyone? If it doesn't work, they don't pay.

    I just have a hard time believing it's a viable technology since it's been out there for 25 years and no one has even published a peer-reviewed article on it. Think about that: The biggest single achievement in the history of the world - and for 25 years they've not been willing to provide proof? Shockley invented the transistor in the late 1940s. Within about a decade, Kilby had come up with the IC. Within 25 years of inventing the transistor, Intel was stuffing 3500 of them onto a piece of silicon the size of your fingernail and calling it the 8008 processor. <br /><br />In case you hadn't noticed, technology moves MUCH faster today. At this point, we should be able to buy LENR devices at the local Home Depot or Lowes… if not the local 7-11 or Dollar General store… if the technology works. <br /><br />OTOH, if it DOESN'T work, one would expect more "mystery". The announcement of units selling now argues against fraud - but I've seen no reports of buyers experiencing success. Have you?

    We'll see. I've talked with Andra Rossi, and also with their US counterpart. I'm interested in integrating one of their systems onto a robot for something like a disaster site relief (Fukushima or something similar) where it would need to run for a very long time without people near. We'll see.

    <a href="http://coldfusionnow.org/first-commercial-cold-fusion-steam-heat-generator-for-sale/" rel="nofollow">http://coldfusionnow.org/first-commercia...</a><br /><br />So, they claim they have a commercial unit selling now and will have consumer units within a year. <br /><br />My bet is that if they stick to the schedule, someone will be hauled into court within two years. <br /><br />I'd love to be wrong, but if I were betting, I'd lay the money on "this is fraud".

    Well read the site I sent you. A team from MIT is selling demonstration NANORs, I'm on the list, they just announced it a few weeks ago. <br /><br />Andrea Rossi has demonstrated his technology to multiple independent third parties, who have all concluded there is no known conventional reaction that can produce that amount of input vs output energy. <br /><br />Industrial Heat just spent some $10M (I forget the number) to purchase the US rights for Rossi's work. <br /><br />The process itself is being investigated by numerous people, Rossi's and the MIT team's seem to be the most advanced. MIT is more open with theirs than Rossi is, but, let's be honest. If you had something like a fusion energy production device that could be easily reproduced (read: China, et al), would YOU let just any dingbat get a hold of one before you had the production capability already lined up and ready to chunk them out?

    I had an off the wall thought... regarding refrigeration. And knowing it is, actually, a very vital part of a survival situation (especially if you happen to be insulin dependent)... <br /><br />Using a ammonia-H2 Refrigeration unit (think Dometic or other propane fridges) convert the propane burner to a candle. It would take some futzing around, and you may have to make a mechanical thermocouple to adjust the proximity of the candle to the coil (temperature control) depending on internal refrigerator temp, but that would give you a truly EMP-proof fridge that (as long as there are bees, and as such, beeswax candles) would survuve even a lack of available propane...

    Thank you, BambiB. <br />Since the only thing it is crucial to keep going is the refrigerator, it is then plausible to keep the emergency solar power kit somewhere aside and take it out for use as necessary. <br /><br />Jan

    If you don't ground it, the shield becomes a big capacitor that will discharge when something comes in contact with the cage - like you. <br /><br />And EM waves go right around corners. Check out diffraction patterns.

    A semiconductor device that is not physically connected to a voltage source in an EMP situation is still connected to other conductors that will generate a current and voltage in an EMP. So there is no such thing as a closed circuit for a solid state device. <br /><br />Even with physically disconnected electrical devices the gap voltage has to be less than generated by an EMP, which may not be the case in which case the devices may be fried in that circuit. Perhaps you should learn a little physics before you comment.

    Actually, a semiconductor may definitely be an open circuit in the sense of "physically disconnected"… when it's physically disconnected! "Physically disconnected" is precisely what I had in mind. That is what "open circuit" means. I believe I already addressed the case where a device in a CLOSED circuit has its rated voltage exceeded… oh look! There it is! <br />"If the voltage exceeds rated values for various components, they can be damaged," That included semiconductors in closed circuits. The reference to a solar panel "in a box under your bed" was intended to make it clear that I was referring to units that were physically disconnected. <br /><br />My bet is that if you have a box full of diodes, transistors, and other discreet components, subjected them to a pulse, they'd be unaffected. As soon as you put them into a circuit where they form a physical "loop", they become vulnerable. Even a coil would be unaffected so long as the induced voltage is not great enough to span the air gap between the two leads or break down the insulation in the winding.

    ;-) Thank you! (--blush--) Always thinking about possible future needs... <br /><br />Don't get me started, tho, or I'll carry on about buzz coils, flywheels containing an AC magneto, er, 'generator", and an ignition timed off the pulses of said magneto. 20 HP, 15 million units, put the world on wheels and absolutely confounds 99 44/100ths % of most of today's "automotive service technicians"... <br /><br />Or perhaps hot-tube ignition, where one can operate a gasoline Internal Combustion engine cycle without electricity... if it worked (albeit negligably compared to today) in the late 19th century, no reason it couldn't be adapted to use in a non-electric grid down situation... <br /><br />Shall we talk steam without the "punk" part? I remember talk of a modern steam auto, but for some reason no one remembers the work of Abner Doble when designing one... (and if you adapr the aforementioned hot tube to light the boiler stack, with a mechanical linkage to maintain pressure and temperature at the boiler head...) <br /><br />Um... did it get warm in here all of the sudden? OK, I'll let you catch your breath while I go take a cold shower... --giggles--

    WOW! Gensets and faraday cages and windings and speed controllers all in one post. Well done! <br /><br />Engineer porn!
