--Right now any high capacity battery has toxic components that will do the same thing. Let's take a couple of these new batteries, break them open and you wash your face in what comes out of them, 'k?--
But washing your face in gasoline is ok?
I wouldn't do either one... but my point is that AFFORDABLE battery technology still raises the specter of disfiguration and worse in an accident and the newer ones which might not will not be AFFORDABLE without more gubmint subsidies for a long time to come. Subsidies I am NOT willing to see continue.
