Karl Brauer, Editor in Chief at Edmund's has his own blog on the site, and in the latest installment, he highlights an electric motorcycle that I have heard about before, the Killacycle. What I did not know is that the cycle is capable of making a run to sixty from a standing stop in 1.4 seconds. The lithium ion batteries for the cycle come from A123 Systems and cost $12,000 in this one-time application. Karl thinks that if these batteries are available right now for an electric motorcycle, and have been super reliable, then we cannot possibly be that far off from a reasonably priced plug-in hybrid. I think his argument makes perfect sense. Everybody who reads this site is probably familiar with the idea of economy-of-scale. Basically, the more of a product you make, the less each individual product will cost. Makes sense, right? If batteries like these were made in the amounts necessary for a midsize car which sold, say, 50,000 units per year, that $12,000 battery pack should go down in price. That is the idea, at least.
