Transport committee  We're not doing that particular product.

Transport committee  No, that's with their own natural gas, spark-ignited engine.

Transport committee  It varies.

Transport committee  Yes.

Transport committee  It's public knowledge—there are two press releases about it—that we are working with CN and Gaz Métro on a program partly supported by Sustainable Development Technology Canada. The project is to develop and test, with CN, a transcontinental locomotive running on liquefied natural gas.

Transport committee  It will likely be like a tender car in that it will hearken back to coal-powered rail. The fuel will be in a tender car. It will take the weight of the fuel off the locomotive itself. That tender car could potentially provide the fuel to get it across Canada and back again.

Transport committee  The majority of them are what's called bi-fuel. They seamlessly switch if one fuel runs out. But the dominant fuel is always natural gas. The F-250/F-350 product, our Westport WiNG product, which we're doing with Ford Motor Company, will be bi-fuel. That means they will predominantly run on natural gas.

Transport committee  They are predominantly designed to run exclusively on natural gas. For example, Transport Robert's trucks, if needed, can idle on diesel alone, but they were designed and configured to run predominantly on natural gas at all times.

Transport committee  Yes, our regulations—because it's a compression ignition engine, so the type of engine and size of engine as well—require certain conformance to certain EPA standards. There's not really much getting around that.

Transport committee  At this time, no. We've worked with the EPA on harmonizing standards for natural gas vehicles, and I spend a lot of time in Washington, D.C., meeting with them and talking about the standards around natural gas vehicles. We have a very distinct advantage with this new greenhouse gas regulation for heavy-duty trucking, that natural gas is well ahead of diesel, but that advantage will erode if we don't keep our product ahead of the curve as well, which we fully intend to do.

Transport committee  Absolutely.

Transport committee  There are 871, as of April 30, 2012.

Transport committee  Their revenue was $264.7 million for calendar year 2011, up from $144.4 million in calendar year 2010. Over the last five years there has been a compound annual growth rate of approximately 32%.

Transport committee  Yes, and it was spun through the university's industry liaison office. So the patents for the technology were held by the University of British Columbia, and they were spun out as a company.

Transport committee  That's a good question. I think there were maybe eight or ten initially. They basically occupied a small lab space at UBC for the first couple of years.
