Everyone says this is a tremendous market. They don't understand why airlines don't realize it.

That's my most serious concern. That is really being your own worst enemy.

They were behind, and then they caught up, and then they got behind again. The amount of money in the matter of a month or two became excessive.

Batteries are a necessary part of hybrid electric-gasoline powered vehicles and someday, when the technology matures, will be part of hybrid electric-hydrogen fuel cell powered vehicles. Current hybrid vehicles use nickel-metal hydride batteries, but a safe lithium-ion battery will be a much better option for the hybrids.

We want to develop a battery that has a graceful failure - meaning that if it's damaged, it won't cause other problems. We have to understand how batteries fail and why they fail.

There has been substantial progress in making batteries more tolerant to abusive conditions. It won't be long before these batteries will be used in gasoline-electric hybrid vehicles. And the great thing is this technology will be able to transfer over to the electric-hydrogen fuel cell powered hybrid vehicles of the future.
