  • J.C. Penney - More Likely To Hit $50 Than $0 [View article]
    Very interesting article. The window is closing on PbC advantages over Li-ion architecture. We must hope the window is closing 'very' slowly.

    Pure lead is approx. 312kg/cuft. Container is 1280 cuft. Container filled with PB is ~400,000kg. Shipment is actually ~9000kg. 9000kg/400000kg=~2.2%

    If, as some suggest, the shipping container described in MrI's copy of 'bill of lading' contained only lead electrodes - a quick calculation shows that the shipping container contains only ~2% product. A very inefficient shipment regarding product and space. I suggest that the shipment may in fact be 'dry battery'...perhaps all battery components - less C plates- to assemble the AXION PbC battery. These components may be proprietary to an asian company - thus AXION ships the completed product back OR as most of us initially thought, parts made to AXION's specs for future axion sales. There is just too much space in this container IF it contains only lead electrodes.

    Sorry, just noticed this is an import, not export...so internal components for battery before assembly. Keep in mind the 'electrode' is generally attached to an infrastructure of lead that hides inside the battery. The electrode is like the 'tip of the iceberg' concerning the quantity of lead used to connect plates.
    Sorry for the misinterpretation. Also THANKS to MInvest for the actual shipping info.

    This is an order for batteries - not lead electrodes!
    Look closely at the description -written for someone who may visually inspect contents.

    DRY BATTERY(LEAD ACID BATTERY LEAD TERMINALS PLASTIC PCS RUBBER CAP)THIS SHIPMENT CONTAINS NO WOOD PACKAGING MATERIALS

    It says- you should see dry batteries - that look like lead acid batteries (w/) lead terminals (w/) plastic pieces (and) rubber cap (on lead terminal) Many batteries now have built in plastic handle for easy handling. Perhaps the reason for 'plastic pieces'.

    PY - a very good list. I agree. The only major problem I see is lack of foresight from CEOs and elected officials. Short-term incentives like pay bonuses and re-election, respectively, keep us from moving forward unless stockholders/voters exert clear & forceful direction (with consequences) for these leaders.

    To help some of us think about the Axion battery , one might think of an analogy with a water dam (potential energy source that is easily converted to electrical energy using a turbine/generator at the base of the dam). A conventional lead-acid battery is analogous to a dam with a large shallow reservoir behind it and a single stream bringing water to refill the reservoir as electrical generation reduces the volume of water (energy)behind the dam. In addition, the streams/reservoir are weedy. The axion PbC battery has a reservoir that holds less water but the reservoir is deeper (narrower) and is refilled by multiple less weedy streams. This axion 'dam' can recharge more quickly (multiple streams) and last more cycles (slow growing weeds) but for any one cycle (reservoir fill/empty) outputs less electrical energy (-less water behind the dam = lower specific energy density). The 'deeper' reservoir corresponds to a higher charge acceptance or voltage for the axion battery or greater 'push/force' on the dam's turbine/generator. No analogy is perfect, but I hope this helps the less techie among us.

  • A Shift In The Fueling Paradigm Is Coming, Driven By Tesla Motors [View article]
    As popularity increases I imagine having to wait at a charging station (remote) for two other folks (3 x 20 minutes). In one hour I can move on. So 'filling up' will be a very uncertain event. Being impatient americans - these instances will keep the electric car as a niche vehicle to be used around town or longer trips when time is not an issue.....rarely.

    Sorry. On the links 'abstract' page download the pdf version (or view as 'html') of the entire research paper . You will find fig. 6.

    RAISING AWARENESS

    A couple days ago VictorG45 directed this blog to:
    http://bit.ly/17LFFCJ
    I contacted a physicist cited by the article. Here is his response.
    I have thanked him for his 'thoughtful reply'.

    Hi Gregg,

    Thanks for reaching out. I am sorry that you found the press release disappointing. I have little control over journalistic interpretations of my work. Journalists seek controversy, [I] stick to the physics. Please find the peer-reviewed article here: figure 6 should be of particular interest to you.

    http://rsc.li/1dX2HL9

    A couple of things.

    1) I will certainly contact Axion and other promising storage technologies, Aquion for example, to obtain life cycle data. Four variables determine the energetic performance of a storage technology: roundtrip efficiency, depth-of-discharge, cycle life, and embodied energy per unit capacity. In past experience when contacting companies they are either ignorant or reluctant to release these numbers unless one of them is a point of pride. The data I acquired for this study come from respected published documents available from Argonne National Laboratory and the Electric Power Research Institute. I hope better more current data becomes available. I think open source databases like DOE, Sandia's http://bit.ly/STQHiV are excellent. I hope companies participate. I'll point Axion to it.

    2) My study should not disappoint Axion, but instead be a claim of pride used by the company. Please refer to Figure 6. This shows the number of cycles that need to be achieved by a storage technology in order to store wind at energetic benefit to curtailment. Plug in the numbers for your technology use it to advertise or focus R&D on the limiting variable.

    3) Despite lack of data for promising technologies I highlight there existence in the discussion section and point to 3 sources.

    4) The goal of the paper was to develop a theoretical framework that could be used in policy and research. We focus on macroenergetics at societal scale for future energy systems that will mitigate climate change and facilitate a transition from carbon intensive to low carbon energy resources. The data is second to the framework. The data will change. Learning will occur and storage will get better. So will smart grid, efficiencies, transmission, etc. We set an energetic benchmark (curtailment) that adds to a discussion dominated by financial benchmarks. If a financially cheap carbon intensive storage technologies win out than as a society we've missed the point. Axion certainly is a huge step in the right direction.

    Again thanks for your email and thank you for your suggestion in contacting Axion,

    Charlie
