We certainly have curious researchers, but our shareholders demand that all of our research be market driven and customer driven.
In our early days, when we came out of UBC, I think everyone wanted to build a really cool mousetrap, but ultimately, in a very short period of time, we realized we had to develop products that were targeted at markets that would adopt them.
We've evolved over time. Initially our products were very much focused on jurisdictions in the United States and around the world, for example, that did not meet air quality attainment standards, so that was our target market.
Today our target market is on industries that are under increasing pressure from rising petroleum prices and are looking for economic alternatives. Many of the alternatives out there have not been economic, but natural gas is one of the few that provides a very economically superior alternative to petroleum under the right circumstances.
