You're right, but this isn't the manufacturing phase, pre-commercialization or even the demonstration phase we're looking at. This is early research. Whether it's looking at other metals instead of gold, determining whether the amounts needed can be reduced, or any one of a number of other things, this is really only a first step to look at the feasibility of a concept.

A 200,000 cycle battery would power a 200 mile per charge EV for 40 million miles. At 20,000 miles per year, that's 2000 years of driving. You could pass your EV (or at least its battery) down through 60 or so generations. Talk about gold as a family heirloom! If I read it right, the original article seems to be saying that the gold isn't active material in the battery (which figures), but rather a carrier of the active material. Thus it's not really comparable to a silver-zinc battery. It also says that the amount of gold used is "minuscule," but "that would still make these batteries be expensive to manufacture." It also postulates that some cheaper metal might work too. IF this battery design pans out, and I'm sure it has a LONG way to go before it will ever be scaled up for production, it seems like the kind of battery that NASA would use. But it would in theory have such a long cycle life (again IF it pans out) that it would far outlast any device it powered, so I just don't know what its application would be. IBesides, I suspect that battery manufacturers would prefer to make batteries that have to be replaced now and again. :-( David Roden - Akron, Ohio, USA EVDL Administrator = = = = = = = = = = = = = = = = = = = = = = = = = = = = = EVDL Information: http://www.evdl.org/help/ = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Note: mail sent to "evpost" and "etpost" addresses will not reach me.
