Am I the only one who thinks they should just cut the thing open? I mean its nice that its been running for so long but if we cut it open we can use the knowledge from that to make more like these...  What's more important? Having the chance to discover a huge leap forward in the storage of energy, one of the biggest technical problems of our time, or being able to say in  few years that there's a battery in a museum somewhere which ran 200 years?
