Mr. Sullivan, thank you for your question.
I don't think I could speak for the purchasing decisions on a local level that municipalities or transit commissions or transit authorities undertake, but I too share your concern about the impacts of emissions from diesel engines, particularly in dense urban environments.
Within my organization we're working to get a project afoot with a Canadian company that manufactures light rail railcars for high-density urban applications globally, as well as in Canada. We're looking at getting them partnered with a fuel cell company and to look at the prospects for leading a shift in the way hydrogen is viewed in the context of a people-mover solution in densely populated areas. The hope here is that potentially that could help to drive the creation of a more localized hydrogen infrastructure at the municipal level as well, which then creates other opportunities, but, again, the basis for all of this is the electric drive system. The hydrogen is just the energy source; the drive system is still electric.
There is some work, and we're going in that direction. I have to remind people that my organization is full cost recovery, so as we have resources and bandwidth, we try to work towards that agenda.
The other thing you mentioned was the contactless electrification of passenger rail. I believe it's a Canadian company that owns that technology.
