Thank you very much, Chair. I'd like to thank our guests for being here today. I find your testimony thus far very helpful.
Mr. Facette, you made a reference to our London police force using propane for their vehicles. I'm proud to say, being from that city, that we have certainly embraced that technology. In fact, it was rather interesting. We made a decision, because of the challenges in Ford Talbotville, to buy up all the Crown Victorias they had so that we could put them in storage until we could utilize them again, with the notion of converting them. We also have probably the largest taxi fleet, Aboutown, that not only has all of its vehicles on propane but is a propane supplier, as well, across the city.
I'm trying to understand better the economics of all of this, and the payback. Mr. Facette, I think you said that depending, of course, on usage, it could be as little as a nine-month payback. Mr. Shaw, I think you said that potentially you would set that out generously as a three-year plan. If you'll forgive the pun, why haven't conversions exploded?
