I had not thought about that a self-destruct button maybe? I don't know, I'm going to be realistic I don't think this project started for ecological reasons, I bet was around the oil crisis of the 70s so it was more towards the economic, but if it has deeper roots and they want to use a weapon that would be badass. Like Iran's nuclear program that was supposed to be to develop a nuclear power plant and then someone said it was to create bombs, I really do not know how that ended.
