  • Understanding The Grid-Scale Energy Storage Boom [View article]
    Power and Energy are two sides of the same coin. Axion's systems are generally focused on applications that need enough energy to carry a user through 15 minutes to two hours of grid failure. ZBBs are focused more on users who need two to seven hours of protection.

    There are very few bright line distinctions in energy storage and the easiest way for me to think of systems is in terms of discharge durations of seconds, minutes and hours. Systems in the seconds and minutes class are generally considered Power applications while systems in the hours class are generally considered Energy applications.

    Ultimately the end-user will pick the best technology for his specific needs and there will be plenty of demand to go around.

  • Understanding The Grid-Scale Energy Storage Boom [View article]
    A behind the meter system is owned by a power customer that wants to ensure backup power and power reliability for an installation like a factory, datacenter, hospital or other installation. The Axion and ZBB systems are focused on that market.

    The A123 and Beacon installations have either been in front of the meter at wind farms and similar installations that want to stabilize power before feeding it into the grid, or grid-based systems where they're an integral part of the transmission and distribution systems.

    Conceptually you want to think of the grid as having three parts:

    * A power generating facility that's separated from the grid by a producer's meter;
    * The transmission and distribution grid itself; and
    * A power using facility that's separated from the grid by a consumer's meter.

  • A123: Clear Sector Leader In Lithium-Ion Battery Space [View article]
    While many of the markets A123 is pursuing seem to be likely money losers, there others where it may be able to earn a profit. Much depends on whether their new factory gives rise to all the economies they've been promising. I'm generally skeptical of claimed economies of scale, but I am willing to give them the benefit of the doubt when the stock is trading very close to book value.

    The stock was up this morning and it's flat now. That's one of the best post financing announcement performances I've seen in a long time.

  • Why The Electric Vehicle House Of Cards Must Fall [View article]
    It seems to me that governments are retreating from policies that favor unworkable alternatives like solar power in Germany and electric drive almost everywhere. The voices of the advocates are as loud as ever, but the voices of common sense are being heard where it counts.

    Humanity can't make enough fuel substitution machines like EVs, wind turbines and solar panels to make a significant dent in oil consumption. The only way to conserve hydrocarbons is to use them more efficiently.

    Governments cannot support policies that cost $10 to implement and only save $5 worth of oil because the policies can't scale and are fundamentally fraudulent. It's a cruel world and solutions that can't make a difference won't make a difference. Wishes and hope are not investment strategies.

    In the last reader comment to this article JRP3 provided third party links that reported the average days in inventory for the Leaf during the last three months of 2011.

    In October, the average days in inventory was 10
    In November, the average days in inventory was 14
    In December, the average days in inventory was 26

    The trend is the exact opposite of what one would expect with a high demand vehicle.

    You've raised an interesting question HTL so it's time to "stump the expert." My 200-day volume weighted moving average is $0.567. The 200-day SMA is $0.591. How do your calculated resistance points interact with the long-term moving averages?

    I like your reference to "green smoke and mirrors" and will no doubt steal it without attribution. OK, maybe I'll give you credit for the phrase, but not every time I use it.

    Private placement shares are always restricted stock in the hands of the original purchaser, even if they're eligible for resale.

    When private placement shares are sold, additional back office procedures must be followed before the shares are treated as "delivered."

    Shares that are sold by a market maker today but can't be delivered until the back office compliance is completed are reported as short sales.

    I think!

    You don't want to adjust individual trade figures. The 111,000 was a block that traded. The other side for the double count would be a group of trades that total 111,000 shares.

    Electric motor technology is very well developed and building a motor to fit a specific use profile is no great feat. I've never said EV motors were off the shelf components, but they are components any one of a dozen different manufacturers could readily manufacture in existing production facilities using off the shelf components.

    Pretending they're something special is either ignorant or dishonest. Which term describes you better?

    It's always a bit flattering to be quoted in context and in full. Thanks for the compliment.

  • Finding A New Investment Opportunity: ZBB Energy Receives ETL Certification To UL 1741 For Enersection Power Control Center [View instapost]
    The PowerCube is a 500 kw system that's designed to provide full plant-level power quality and reliability, along with demand charge management capabilities. In addition, 100 kw of that capacity is being used to provide frequency regulation service on the other side of the meter. The net result is a plant-scale power quality system that costs far less at the outset and generates ancillary revenue to reduce total cost of ownership even further.

    It aggregates several values to the owner rather than serving a single purpose.

    I've tracked long-term moving averages for decades and found them very reliable trend predictors. Short-term TA, on the other hand is one of those black arts that presumably starts with cutting the head off a chicken. I don't do that stuff.

    Let me be the first to congratulate you on a solid first piece. If ZBB wasn't a sub-$1 stock, there's a good chance the editors would have picked it up for the main pages. If you enjoyed the experience, keep plugging away and you'll get there.
