I would like to tell you that it's not that far. To be frank, the technology is coming fast. That's why I keep telling my counterparts in my industry we have to move now, because there's going to be a new technology tomorrow. If you don't move now, you're stuck for the next 15 years with an old technology. We can't afford to trade in the trucks and trailers every two or three years. Our business does not allow that.
Carrying cryogenic gas on our trucks is one way to get to tomorrow. Maybe tomorrow will be more creative. Right now, we have a problem of autonomy. We don't carry enough gas on our trucks. Maybe eventually we will have a tank under the trailers that we can plug into the truck, which will allow us to get the natural gas into the truck so that we can carry more and have greater autonomy, and that way we can get into the boonies without a refuelling station. Right now, we can't do that.
To answer your question, I strongly believe that with the creativity of the research people doing this, from what I've seen it's not that far away. It may take longer to commercialize it, but for a lot of people, unless you have to change, you don't change. People are not enthusiastic about changing for the sake of changing. They want to change because they are forced to change. Eventually, I believe, I will have a museum of old trucks; maybe one of these days I won't be able to run them anymore because I won't be able to get fuel to put into them. You understand? They may be worth nothing.
I used to have an iPad 1. My grandson took it. I got an iPad 2, but now my granddaughter wants it, so I'll have an iPad 3 soon. Just to illustrate, in a year's time, we went through three iPads. What are we going to go through in terms of technology is a very good question. My feeling is that natural gas is the first step to get into a new type of gas. As soon as you get into cryogenic tanks, you have gone to step number one. Are we going to have combustion engines tomorrow? Are cars going to be like a locomotive, just an engine running on generators and batteries, with electricity powering the wheels? Probably.
If you go to Europe, you can see this. If you go to Hanover, you will see buses running 100% on electricity, with a small engine at the back that starts if they need it. It's a small generator. They just recharge the batteries so that they never run out of power. The engine is that low. That's all it takes.
