 A commercial cement plant that's been built 3,000 times before takes two or three years to build. So in the next five years, we will be working on building a first commercial plant. I think it's probably unlikely that it's fully operational. Within five years? Yeah. And who do you think your initial customers will be? A lot of these huge construction companies probably have massive contracts with massive cement manufacturers. So what do you think your approach is going to be? So it's a pretty complex market.
