Why do you think Tesla acquired Maxwell, then? Why did Maxwell sell existing lines of business several months ago to focus on the dry battery tech and ultracapacitors? I don't know enough about dry battery electrode tech to know how much progress there is, how much an of an improvement they are above existing commercial technology, or who else has IP in the space. Your response seems a bit high on the cynicism/information ratio, but I would be genuinely grateful for more information about this.
