I am a huge fan of alternative energy sources and lithium batteries definitely have a place in the future I personally don't see how daisy chaining thousands of 18650s together is innovative for the purpose of personal transportation. I have personally seen lithium batteries melt down and know that I don't want to be trapped in a car with thousands of them. Not to mention that he created thousands of points of potential failure with this battery bank design. Musk is a hell of a good marketing man but I just don't see how this is considered innovative or practical.
