We are still in discussion with industry. One of the reasons I'm back here east from Vancouver is that we just had meetings yesterday with two concrete producers, and we shared results with them from our latest study at UBC. I'll comment from this side as well that the nice thing about working with universities is that we're working with established professionals in centres of excellence, so when we have a professor, who is in essence world-renowned in this area, and who conducts research on our behalf, that credibility and expertise they bring to the table goes a long way.
Just in our call yesterday, the professor we're working with conducted... The call went through...the slides that he did for us. Some of the questions we asked of him were answered very well, so we're well on our way to getting this into field trials.
We do expect that by the end of this year, if not this summer, we will have field trials on a concrete site.
