The primary thrust of the research has been with cars. But the (fuel cell) technology can also be used in remote power systems and future uses for cell phones, computers and other batteries.

I am certainly not optimistic in the next five years. In 10 years I think we're going to get to see quite a few (fuel-cell vehicles), but probably not before 20 years in terms of a really big- scale application.

We see that as being a very green way of going. It's something that you can run very easily off of solar or wind to generate the electricity.
