Yeah, great question, Craig. And if you look at the total order backlog and even you go back to Q1 of 2020 where the order backlog, total backlog was about a 108 million and today it's about $57 million and the -- I'm talking about for Technology Solutions, by the way, not the total order backlog. So it's gone from about a $170 at the start of 2020 to about a $109 in total at Q3, 2021, the big change there is a point out is the Technology Solutions has dropped off from about a 108 million to 57 million. That's really the execution against the Weichai technology -- Weichai Behler Technology Solutions program, and the execution against the Audi program. And really what we see going forward is the power products, heavy-duty motive being the driver of growth. And you think about all these markets we've talked about bus, truck, rail, and marine, where we've got bus OEMs in Europe, in North America, and in China with Ballard products already inside their platforms, with truck OEMs, starting to and the work we're doing on the truck market with Weichai in China and with Mali in Europe and for light-duty truck with Linamar or as well. And so that's a passenger van. And so when you look at a number of these programs, including rail and Marine, they will take a number of quarters, even years, before they start to see development in the order book. But again, I want to come back to this point. If I look at the order book for heavy-duty motive from Q1 to Q2 to Q. in 2021, it's up 30% since Q1. I want. And to me that's the real story is that we're seeing the market take up even with China being light. We're seeing the market take-up in Europe and the U.S. for heavy-duty motive, where we expect to see the lion's share of growth moving forward. So I think the question is, when we -- when will we see -- what's the linkage between when the order book starts to materialize and then subsequently revenue. I think it's a year is about right. And some of these cases, projects will take a year to execute against, as customers go through hydrogen refueling stations, as they go through getting the engines into their platforms and getting ready for deployment. So we've seen that historically in the bus market and I expect to see a similar thing occurring in the truck. A marine and rail market where you've got 12 potentially up to 18 months before projects go from order book to revenue.
