I can take a very quick shot. When we present our technology to the industry, it's not as though people say no. They say yes, and they say yes very quickly.
We have relationships with Canadian Natural Resources, with U.S. Steel Canada, or now Stelco, and St Marys Cement, which is part of a large international conglomerate called Votorantim based in Brazil. It's actually our single largest shareholder and investor.
It's not as though there's an unwillingness to look at the technology. The rub is that industry moves very slowly. It takes it a long time to implement.
