Yeah. By the way, great question. So first of all, we absolutely will be building these directly ourselves, in particular, in North America for sure. This is a specific application and architecture of the Gravity Energy storage technology that this specific developer has been talking to many customers about developing and implementing. So we did a specific license agreement with them and essentially we'll begin that in those implementations, in the western part of the U.S. So it is not a necessarily a reflection that all Gravity will be licensed. But in some parts of the world, as we've seen, for example, with China, we announced Egypt, Greece, and Cyprus. And for some aspects of the technology the license model fits really well, because we're obviously not in the construction business ourselves. Obviously, we'll manage EPC relationships and manage the build of the projects. And this is essentially a larger construction project with electronics integration, power integration and software, and actually tends to be a very logical frame for doing these types of license agreements and for investors, Tom, they're fantastic, because we not only benefit from, essentially 90 plus gross margin on the license portion alone. But then there's the follow on royalty streams, that as we've publicly announced before, these are done at about 5%. And again, those are streams that will be at 90% plus gross margins as well. And we're not taking execution risk in that case. And I think from a business model perspective, it allows us to monetize our technology and our IP, especially for certain applications or iterations or new architectures in a way that has us garner that profit and even have that -- a lot of that profit, a little more risk free, let's say, as others can focus on getting the technology built out.
