RE:TransportationJack Bauer: The batteries are for mass storage and are most competative at shorage of over 8 hour duaration. The batteries are much heavyer than LI-ion which actually is too heavy for vehicles. The lite weight battery for vehicles is Aluminum air which is also in developement at about the same pace as Zinc-air batteries.
The denrite problem with Zinc air has been solved by a company in Ontario and has been solved by Zinc8 as well. Both batteries at this time are too expensive to be competitive.
GOOD LUCK TO ALL INVESTORS.
