  1. Re:Hope they speed up developing real batteries on Arizona Approves Grid-Connection Fees For Solar Rooftops · · Score: 1

    Private energy systems won't be able to compete on price, making autarkic electric power systems an expensive toy for people with too much money at hand or too much paranoia in the brain.

    Private energy systems won't be able to compete on price, as long as the electric company's rates stay reasonable. If the power company gets greedy, suddenly the alternatives start to become competitive and the power company starts to lose customers -- a possibility that I'm sure the power company will be well aware of.

    So even if almost nobody ever actually buys a home-battery system, the fact that they could buy one would serve to place a ceiling on how much the electric company can gouge people. And the cheaper the home systems get, lower that ceiling is.

  2. Re:Penalty for not connecting to the grid on Arizona Approves Grid-Connection Fees For Solar Rooftops · · Score: 1

    Would the penalty for not connecting to the grid be interpreted as a "tax" in the same way that the U.S. Supreme Court ruled that the penalty for not signing up for insurance that conforms to the Affordable Care Act is?

    I don't know. Would the taxpayers be on the hook to provide off-gridders with electricity during emergencies, the same way they currently have to pay for emergency-room care for the uninsured?

    Well, OTOH that likely means when anything goes wrong with the engine you need an entire new engine

    Agreed -- a whole new electric motor, to be exact. So hopefully the electric motors will be durable.

    For some time, repair of electrics is going to be the province of dealers and perhaps larger shops

    OTOH, one of the (purported) advantages of an electric car is that (outside of replacing tires, and, after 8-12 years, the battery) there shouldn't be much in it that needs repair.

    Of course, with a redneck, they just sling a generator in the back if worried about range.

    This is actually a good point -- an electric pickup could operate like a Volt, without the Volt's requirement to always carry around a weighty gasoline engine even on trips where you don't actually need it.

  6. Re:Old silent SIM firmware on The Second Operating System Hiding In Every Mobile Phone · · Score: 1

    Please. Anyone paranoid enough to take the battery out of their phone to avoid being tracked would simply not bring the phone with them, which is both easy and effective.

    Unless you want to, you know, use the phone later. (Presumably at some time and location where you're no longer worried about being tracked).

    Of course, the beauty of the Internet is that the stupidity of YouTube's top N channels doesn't effect me one bit. The content I find interesting is all there and available as well, and I never need to see (or even know about the existence of) any of the silly channels listed in the parent post.

    Contrast that with television, where almost every show has to be dumbed down to appeal to a wide audience.

  11. Re:Too bad it's a C++ library... on WxWidgets 3.0: First Major Release in Several Years · · Score: 1

    However, I do my programing in C [...] Since I have no particular desire to learn C++

    I think if you learned just the basic parts of C++ you'd find it's much quicker and easier to get things working reliably than using straight C. The trick is to ignore the 253 different categories of nifty/obscure feature you don't want to deal with -- rather, only use the parts that you want to use. In particular, constructors/destructors, inheritance, virtual methods, and basic templates can all be huge time-savers once you're used to them. I started in my programming career using C, but after using C++ for a few years, writing a program in C now feels like driving a car that's stuck in first gear.

    I've played with one and let me tell you, depending on the size, they can hold some serious voltages - I've held one with 5M volts stored. Insane.

    Where would you put this set of battery cells? [...] So do German's have a extra space in their garage for something that may take up the floor space of a water heater or furnace?

    Well, the obvious thing to do would be to put it in the garage, and put an electric motor, wheels, seats, etc around it so that you could also use it for transportation.

    In fact, I think Germany already has some companies selling batteries like that, they just need to standardize on a bi-directional electrical interface to the home's electrical system. :^)

  15. Re:Who will be leaders in solar technology? on Germany Finances Major Push Into Home Battery Storage For Solar · · Score: 2

    Who knows, it could very much end up a repeat of HDTV, with some new photovoltaic chemistry coming out of some little lab which renders all previous PV technologies obsolete.

    That certainly could happen, but the HDTV comparison is misleading.

    With television, you have compatibility issues -- the receivers and the transmitters have to work together, otherwise the technology doesn't work. Therefore when the television stations decided to go with digital transmission, all of the analog gear became useless because it could only process analog signals that were no longer being transmitted by anyone.

    Solar panels, OTOH, don't need to be compatible with anything except the sun. If I buy a solar array for my house this year, and some much-improved solar technology comes out next year, my solar array will still continue to work just as well as it ever did. It's true I would have saved some money if I had correctly guessed the future and waited, but it's not a total loss of investment like analog HDTV or DVD-HD players were.

    I think if 100 Corollas spontaneously burst into flames each year (and realistically, more like 2-300 given that production in the 60s, 70s, and even 80s will be far lower than in recent years)... we'd probably have heard about it by now. Don't you?

    Sure. But we're not talking about cars "spontaneously bursting into flames", we're talking about cars catching fire after having been damaged in an accident. I wouldn't be at all surprised if 100 Corollas a year do that, and nobody bats an eye.

    And I can't understand how that's a premium worth paying for, unless you actually need it for some reason.

    The alternatives are Windows (which I can't stand), or some flavor of Linux/Unix/BSD, which work okay, but aren't particularly user-friendly, and don't have much commercial software support.

    Whether or not paying extra for MacOS/X is worth it will also depend on how much money you have available. If you're scraping by, it might be better to pay less up front, and put up with the shortcomings of an alternative. OTOH, if you've got enough money (or your employer is paying for it), then you may prefer to spring for 3-7 years of hassle-free computing experience, rather than a one-time savings of a few hundred dollars.
