probably because LA is cheaper and because the LI hasn't been fully developed yet. But good luck. Lets talk when this is finally ready for public consumption.. by then there could be many technologies available. Like I said, the world ain't exactly beating a path to the door. Plus, firefly's already to go and they ain't being overrun either.

lightfixer this guy just makes unfounded blathering as he trades in and out. The web pages he references proves your point and not his. PWTC doesn’t get the publicity but we have the technology in a patent, and now in a Pilot Plant. The company could very well fail because of financial but the technology will survive and may be sold off in the end.

1. Lead acid technology has a Unique niche advantage.
From the Battery Man article on Firefly:

http://www.evworld.com/view.cfm?section=article&archive=1&storyid=877&first=2506&end...

On the question of performance, he explained that basic lead-acid chemistry has always had -- theoretically -- very high energy and power densities, which could never be fully exploited due to the limitations of current battery design.

"Our point is that if you look at the claims made from a single cell standpoint for lithium -- those single cell performances can be very high -- what happens though is you have to put a lot of controls on it to throttle its performance when you put it into a multi-cell application because with those technologies you worry about such issues as thermal runaway. Those kinds of requirements with lithium ion really move and shift your performance in terms of specific energy and specific power back down and to the left.

"So our point is that when you talk about an application now, instead of a single cell performance, we start to arrive in that same, similar sweet spot as where nickel metal hydride would fall and where lithium ion falls in terms of a multi-cell application. We do so with a far better cost structure, number one. And number two, the ability for our technology to operate in broader temperature extremes is much better than is the case with lithium ion and nickel metal hydride".

2. The technology is not limited to Lead Acid , Snapper’s team realized the technology is applicable to other metals. Applying the technology to lead had the least technical hurdles and is most obvious route to market.
