I'm sorry to interrupt you, but we did have a witness a little while ago regarding battery technology who essentially said to us that nobody knows when battery technology is going to get to where it needs to get. Even though they've done more than 30 years of research, he indicated that there's a good chance we're looking at another 30-plus years before we actually get to that point. I think we've got to be careful making assumptions that we're that close, because we've had experts on battery technology who have told us they don't believe they're even that close.
