Part that is telling for me from this article is the reality of lithium and its  advances over the supposed superior Estor tech .

Kind of reminds me of the VHS killing the supposed superior Beta tape system.

Litium is in the game and locking in application to industry. Estor is -----basically invisible.

This tidbit really says it all for me.


One could argue that EEStor, through its delays, has lost its window of opportunity and that the rest of the technology world has caught up. The batteries used in the higher-end version of the Tesla Model S, for example, boasts 240 watt-hours per kilogram, not far from the original EEStor goal of 286 watt-hours per kilogram.

Newark, Calif.-based Envia Systems, which counts General Motors as a strategic investor, claims it has reached 400 watt-hours per kilogram with its lithium-ion technology and could hit the market with a commercial product by 2015.

But EEStor has since upped its game by claiming it can double, even triple its original target, even achieving energy densities of more than 1,000 watt-hours per kilogram at a cost that few could – at this point – compete with. Plus, unlike batteries, its device can charge instantly and would have unmatched environmental attributes.

Of course, this is all still highly speculative and incredible claims require incredible evidence. Fool me once…
