Well, I think, Rob, I mean, and Bob said this a little bit, and I think you all know it. These projects have taken, I think it's not, again, unique to us. And I'm not trying to hide behind others. I mean, these projects have tended in the industry to take a little bit longer than many of us thought. Now, not years, months, and ours did. We thought that these projects would conclude in the third quarter, in early fourth quarter. And they took an extra three months of really commissioning and getting them all done. So the time to finish these projects has taken a little bit longer. And I would say they've been a little bit, maybe it was the pandemic, maybe it was the supply chain. We saw an increase in cost in these projects, 10% to 15% to 18%. Now, that's stabilized, but we also know, Rob, that as we go forward, we're going to have to bring in, and I feel certain, we have a project team underway here at Clean Energy, we need to bring in these costs, right? We need to try to systematize and make these more, be able to replicate these projects without the kind of artwork design at each one so customized. And we're working on that now, and others in the industry have brought some new designs of how they might handle the digesters and such. So we need to wring out some of the pricing, bring in the time to market of the construction and the permitting these things, and then certainly the pathway to begin to produce and collect, monetize the credits. There's work to be done. Good news is we're going to need this R&G. Look, if it goes the way we think, and if it goes, if you look at what Cummins is saying, they believe they'll sell about 3,000 to 3,515 liters in 2024. They've suggested in their materials, these are not mine, 7,000 units next year. And then they say it could go up to somewhere between eight and 15% penetration of the Class 8 market. Class 8 market, by the way, is about a quarter of a million engines, so that could be anywhere between 15,000 to 25,000 units in the third year. Well, in that year, you need 300 million gallons, 375 million gallons of RNG, right? Two years, you need 110 million or 115 million. So the industry needs RNG, so you're going to need to drop down. There will be many more landfills coming into the market as well as dairies. And the dairies, the industry has done a pretty good job at tackling some of the largest dairies, but there are many thousands of other dairies that are smaller, so you're going to have to just lower the cost to be able to tackle these smaller dairies. And I feel certain that the industry will do that.
