    Perhaps you should read the article again.

    Bill, a PbC battery weighs 25%-30% less than a conventional lead-acid battery of the same size. That is, instead of a 50 lb one would be talking about 35 lb. Further, the PbCs are not prone to fires or need the environmental conditioning systems characteristic of Li-ion.

    On gasoline/diesel prices, you may be correct in your assessment but your expected price trajectory implicitly carries a number of assumptions. Expansion of auto ownership in China and elsewhere certainly appears likely, but the proportion of added vehicles powered by gasoline/diesel and the fuel economy of those vehicles is far from given. And, I for one look for growing diversity in supply sources of liquid hydrocarbon fuels with declining reliance on petroleum due to improving gas-to-liquids and biofuel technologies. The last thing I expect to see is world wide (or even industrialized country) development of substantially electrically powered vehicle fleets.

    >Goldie+Shadow -> "I was a P Chem major in college and can tell you that the transfer and storage of electrons is a lot more efficient in lit ion batteries than lead acid. Completely contradicting John Peterson's view. "

    LOL! Seems to me you don't have a clue as to "John Peterson's view". Have you read ANY of his articles?

    "... 3 new stop start production contracts" makes for good publicity but if one reads the PR one should note the contracts are for STARTER batteries and extoll a 1.5X longer service life. That is, a 50% increase in service life for a battery that likely costs 4X - 5X as much, that doesn't work as well in cold weather, and is made of more hazardous materials that cannot be recycled at this point in time. Further, the PR does not mention "hotel" loads such as radio, time and temperature displays, air conditioners/heaters, etc. that will certainly be present in a modern auto.
