That's a good question. I believe that is going to happen if we commit ourselves to requiring the fast-charging DC infrastructure that's necessary. For instance, today in Ontario we have only 94 fast chargers versus thousands of gas stations. If you consider everybody is moving in that direction, if every gas station had a fast charger, then yes, 15 minutes is not a ridiculous time to wait to get an 80% charge.
I would also say that I don't think there is going to be one solution to our zero-emissions problems. We are going to find that there will be multiple solutions, especially, as my colleagues have talked about, with the heavy-duty truck industry, the bus industry and even the train industry being able to run more efficiently on hydrogen. With a hydrogen vehicle, with our Nexo, which you can buy today here in Canada, if you have a place to refuel, you can charge that in five minutes. It's no different from filling up a vehicle with gas. It provides you the ultimate fast charging, plus you get over 600 kilometres on that charge.
Even though we're getting closer to 500 kilometres and although I do believe battery technology will improve, my main point is that whether it's a battery or a fuel cell, without the infrastructure moving faster and even with our industry already investing $300 billion in zero-emission vehicles, we have a problem coming up, which is that we have too much supply compared to the demand.
