Disclosure: I have no direct or indirect interest in Tesla, GM, Nissan or Toyota and I have nothing to gain or lose from any of their stock price movements. While I am a former director and current stockholder of Axion Power International (AXPW.OB), a micro-cap company that has developed a robust, affordable and serially patented third-generation lead-carbon battery for micro-hybrid, railroad and stationary energy storage applications, I can't see how the success or failure of a niche product like electric drive could impact the value of my investment in a company that's focused on much larger and more predictable mainstream markets.
