Million-mile battery unveiled by ground-breaking research.

This thread kind of got derailed, as usual with threads. But the point of the OP's original post was to celebrate a battery that will last a long time, not hold a charge a long time, or supply electricity for a long time, but be recharged lots of times.

IMO, incremental improvement in storage, hardly groundbreaking news. Now a battery the size of a 9 volt battery, and able to power a truck pulling a trailer for 500 miles, that would be groundbreaking, world shaking news.
