The real question is, will this lead to reduction in cost?

If yes, I hope they open-source it so that the fight against global warming can gain some momentum across the globe.

Cost is just one of the interesting dimensions. For various kinds of transport energy may be more important than cost. I would be prepared to pay significantly more for an EV if had range of 1000 km rather than 500.

I think I'd prefer half the battery weight.
