  1. The only good thing that I can say about Wind Turbines is that they only work 22% of the time…It’s soooooo efficient…but it is a nightmare to look at 100% of the time….

    Hey how did they set those things on fire ?…great idea….

  2. Smart Meters:

    To address health concerns about radiated energy when the smart meter communicates with the utility, Elster programs the meters for the time and frequency of transmission. For example, Pacific Gas & Electric, which uses smart meters from General Electric, says that its smart meters transmit for only approximately 45 seconds per day. According to iFixit, if a device were always on, there might be a cause for concern. If what PG&E states about the limited transmission time is true, however, your cell phones, Wi-Fi Internet, and microwaves would probably cause more damage to your body than a smart meter would.

    Some people have expressed concern about smart meter transmissions — one answer.

  3. Rare Earth update:

    There are rising concerns over China restricting exports of rare earth elements.

    Such warnings have at least some validity. This is a big deal because rare earths — a series of elements given their own section of the periodic table because of the unusual properties of electrons in their outer atomic shells — are used in everything from smartphones and hybrid cars to smart bombs. Gadolinium (Gd) and thulium (Tm) are used in MRI and X-ray machines, while ytterbium (Yb) is a key component of most semiconductor lasers.

    Luckily, OEMs need not get into a rare earth panic. A cover story in the Aug. 27 issue of Science News detailed efforts to find cheaper, more common alternatives to rare earths, particularly in high-performance magnet applications.

    The Department of Energy’s Ames Laboratory and scientists at Tohoku University in Japan are revisiting older magnetic materials from the mid-20th century, such as aluminum-nickel-cobalt compounds and thin films of iron and nitrogen, to offer high-performance magnets free of rare earths. For hybrid cars, scientists hope to optimize the use of the rare earth neodymium by turning to nanocomposite materials for stronger, more efficient permanent magnets.

    A global rare earth market less dependent on China is probably a good thing, even if prices on the lanthanides rise by a few percentage points. But it’s also good to see developers talk of replacing rare earths in many electronic applications. They may not be as rare in the earth’s crust as their name implies, but the difficulty of mining and purifying rare earths makes them a manufacturing component ripe for replacement.

    Hope that makes you feel warm and cuddly — scientists everywhere are watching out for your safety and health… Not to mention hoping for patent rights…
