    If all it ultimately does is send some current to 16 or so places at the same time (the explosive charges around the sphere to be imploded) then that isn't hard to replicate.

    When "at the same time" resolves to pretty much exactly the same wavefront within +/- femtoseconds (10e-15), and where said device and design absolutely has to work the first time and the only time, and you have zero testing opportunity, and even the length and placement and coupling of the wires affects the timing, yeah, actually, it is that hard to replicate. If the timing is insufficient to the task, the implosion is misshapen, and that generally means the weapon won't go critical -- you just end up with a bunch of bomb debris.

    The net effect isn't the same.

    A corporation has to ask you for your data, and you can say no -- at which point the corporation is SOL, regardless of your perceived goodness or badness of that corporate use. In addition, the corporation has at least some stake in your continued good will, and so they are likely to give you something back in return if in fact you choose to opt in. But if what they do makes people opt out... without customers, the corporation will cease to exist.

    A government can -- and in the case of the US government, already will, the Canadians are well behind us -- take your data. Once it has it, it can, and will, jail you, take your life, and so on. They don't have to give you anything back, and typically, they won't. They have no significant investment in your good will. You can bitch all you want, but you can't opt out and they won't stop existing because they're annoying some of the citizens. Nor is there any hope of them annoying enough of the citizens for such a thing to happen.

    You're been taught that corporations that do not know right from wrong are bad, thoughtless entities, and they certainly are, but they are nothing compared to a government that does not know right from wrong.

    Also, in the final analysis, it is the government that enables or prevents any particular corporate behavior. If you get control of the government (good luck, too late in the USA.. but Canada... perhaps not) then you get control of the corporations.

    How is this relevant? You need 100 million tons of such high-tech gadgetry for a country as small as Germany.

    Good grief, How many ways do I need to explain this so you can understand it? The tech to do this is NOT HERE TODAY, so you CAN'T ESTIMATE THE WEIGHT using today's tech.

    These questions are currently unanswered: How many farads will ultracaps be at that point? What voltage will they allow at that point? How much will they weigh at that point? What volume will they occupy at that point?

    Therefore, your numbers -- in fact, any attempt you make to to specifically quantify the issue in any way -- are complete nonsense. Got that?

    In closing, I made a general statement, which I will paraphrase for you: WHEN (not if) ultracaps exceed battery capacity vs cost, THEN they will be the energy storage mechanism of choice. I further assert that this is almost a certainty, based on the fact that production ultracaps are improving in both cost and capacity quite rapidly, though they are STILL behind batteries at this time, and batteries are moving targets in terms of capacity as well.

    UC cost, while higher up front, is not what it seems, because in the vast majority of cases (bad units and casualties of other hardware failures excepted) you won't have to replace them until several several human lifetimes have passed -- by which time, for comparison, you would have consumed many, many batteries in the same role. Furthermore, in many storage applications, the ultracap's ability to take -- and release -- charge thousands of times faster than batteries without wear or loss completely trumps battery tech anyway. So even if known, the volume and weight and dollar issues don't adequately reflect the actual "cost of batteries" vs. "cost of UC's." But -- as I said -- we don't know those numbers anyway, because the tech to meet my general notion isn't here yet.

    Now, if you want to write a VALID counter to my post, explain why it is that you think ultracaps will never, or can never, get to the point IN THE FUTURE I indicated: Where they outperform batteries in storage applications. If you have such information, I'm interested. Otherwise, I'm not.

    Nonsense. Maxwell and other manufacturers mass produce them right now. There are so many out there you can buy them on EBay, for crying out loud. And they can be paralleled and stacked in series ad nauseum for any voltage / capacity you require, AND they can be fused / controlled in any geometric arrangement that is convenient, so if by scale, you meant in high power arrays, no. You can do it now. It's just more expensive and volume consuming than it needs to be for a .consumer level practical storage system.

    In order to store 3.5TWh you would need 100 million tons of capacitors

    Sigh. Look, this problem only rationally gets solved -- financially, installation-wise -- at the house level, not at the national level. No nation stores power in one installation, nor are statistics that imply any such thing worth paying attention to. It's like observing the US has 255,917,664 passenger vehicles, so assuming 40 lbs lbs for each car battery, that means the US has invested in a battery weight of 10,236,706,560 lbs (five million tons+), which of course is a vast underestimate because there are all those non-passenger vehicles and other battery users. Yeah, it's a big number, but no, it isn't particularly meaningful or a significant roadblock. And you should keep in mind that the batteries all are dying from day one, whereas the UCs can last so much longer they're effectively immortal. You could literally will the ones in your first car, bought when you were a teenager, to your kids. Nor are estimates of UC weight today particularly relevant when you're replying to an assertion that IN THE FUTURE, the rising curve of storage capacity will cause UCs to beat batteries.

    No. With a simple passive reflector and just a little bit of area, you can achieve temperatures more than sufficient to melt steel, and any temperature in between ambient and there.

    The problem with heat engines isn't efficiency at all -- it's mechanical durability. Live steam, for instance, is corrosive as heck, and machines with moving parts wear unless they are kept in near optimum repair, lubricated and balanced and otherwise made and maintained to exacting and expensive specifications. When you're talking about a power plant turbine, economies of scale let you do the required maintainance and buy the required precision; when you're talking about a heat engine in the yard... you can't pull off the same tricks without a net loss of capital.

    As an engineer, can I build a steam engine / generator combo sufficient to run my home without becoming a net consumer of any kind of significant consumables (water, fuel, etc.) or adding heat to the environment in backyard-class square footage?

    Sure, you bet. Hardly even a challenge, given, say, 20 grand to do it with and a decent machine shop. Can I build it so it'll still be running next year? No. Too much moving crap.

    Nah. It'll inevitably be ultracaps. Capacity is coming up steadily, and when they pass batteries, they'll be the tech to use. Why? Extremely long lifetime; extremely high charge and discharge rates; excellent environmental operating ranges; modular nature and ease of swapping components as they improve or require maintainance; relatively low cost (partially because of life expectancy, partially because they simply aren't that hard to make, at least so far.)

    Right now, UC's are below battery storage capacities and all the hype is about batteries, but that's to be expected. I guarantee you that at some point, all else - pumped storage, molten salt, batteries, flywheels... will fall by the wayside. Ultracaps are the way storage should be done, period.

But if the formula/table is rendered in [color] over alpha, that will work for a lot of cases (although it still fails with [color] backdrops and [other color] text... which is the bottom line use case for "you need typesetting."
