Energy Storage: Chrysler - A123 Alliance Likely to Spark Interest in Sector

Juan,

I follow John's articles and I get the impression that John is critical of the cost of lithium, not the technology, and is skeptical of projected cost reductions and market penetrations. Lithium is without a doubt the best technology where size and weight are critical and cost is secondary, like watch batteries or laptop computer batteries. For applications like cars, buses, trains, or electrical grid backup, wind power smoothing and backup, etc., where cost is critical and size/weight are secondary I sense that John favors existing low cost battery and flywheel technologies and emerging new lead acid technologies like those from Axion, CSIRO and Firefly. His is an informed approach and his arguments make sense. I am sure he can defend himself quite adequately, but as a reader I take issue with your comment which seems to question the integrity of his arguments. Of course he would like the market to prove him correct and make his stocks go up, but then don't we all.
