I may use five minutes here, Mr. Chairman.
You start with diesel. It's an internal combustion engine. Your car uses gasoline. Diesel uses high compression to burn. Westport's technology changes the injector and replaces a portion of the head of the injectors.
Today we use what we call “variable timing” in the engine. That means that the fuel comes to the piston and lights a spark at the piston while the piston keeps going up, and at one point, either fuel or gas comes in. Then the big explosion happens, and this is what makes the engine turn.
I believe that the combustion engine will be here for a good while. Why? It's because this is a solid structure, developed over the years, and in general it is very reliable compared to everything else. If you look at electronics, that's a throwaway situation. If you look at an engine itself, it's very solid. I believe that the combustion engine will stay here for a good period of time.
For the next generation, we need to find a way to break the molecules of natural gas from CH4. Once you bring air into the piston, it will break the molecules and burn only the hydrogen. What I've seen is that you can burn the hydrogen at around 1,200o instead of at 1,700o. First of all, you recoup a lot of energy. You don't lose your energy.
As well, the combustion engine will become much smaller. Today you have to put water around the chambers to cool the engine, and at 1,700o, you need a lot of water. Tomorrow, at 1,200o, we are going to have much smaller engines that are going to burn gas much more efficiently. What I've seen is that the smaller hydrogen engines were producing 35% more horsepower than comparable diesel or LNG engines. That is just to illustrate that the technology will do it.
There are sites on the Internet, but I'm not going to talk about things on the Internet. They are there. Search for Roy McAlister. In the 1990s I had the privilege of meeting with him. This man had an idea 50 years ago that one of these days we were going to burn hydrogen. I swear to God that he is going to do it, hopefully, before he dies.
