A big part of the reason it doesn't exist has to do with how we built up our infrastructure in the country over the last 100 years. We have diesel and gasoline stations. To move to a new fuel costs money and the question becomes: who's going to pay for the new infrastructure?
I think the oil-based companies are probably happy selling oil-based products. They have their own infrastructure that they've paid for already. If we turn around and tell them that they have to set up natural gas at a portion of their filling stations, it means they have to make a new investment. Doubling up an investment in fuel stations is the same as having two sets of telephone lines or two sets of cable. For them, it's not a logical, easy step.
I think if we look at the situation that we're in, in Canada and in the world, with regard to the future of oil, we have to start doing something now to take the pressure off. I was talking to somebody from India who said they were going to set up 50 new international airports in the next several years. Each of those airports is going to have 100 or 200 airplanes associated with it, and they'll all spend 75% of their time hanging in the sky and have to be fueled. If you go to China or Brazil, with all the expansion that's happening, the pull on oil is becoming greater and our capacity to deliver is not really growing. It's going to become a huge issue. We have to find an alternative.
I hope that answers your question.
