Yes, I can. There is a fantastic company in Vancouver called Cummins Westport. They actually build engines for 18-wheelers, buses, and things of that nature. We've partnered with them from time to time. Certain of their technologies will allow you to have virtually the same horsepower out of an engine with natural gas as you will with diesel. Typically it's 98% or just slightly less than that.
What you're referring to is that often people will try to convert a diesel or gasoline engine without doing any of the advanced things, through the technology they have today, to pick that up. Many of us experienced that back 20 years ago when we were trying to run natural gas in our vehicles. You would have a drop-off of 15%, 20%, or 30% of the horsepower.
