Where I'm going with this is that we have a number of contaminated sites across Canada. One of them is the Sydney Tar Ponds, where crude oil has been exposed in the tar pond for periods of time. We have those kinds of contaminated sites around the country, where we have conventional oil exploration and we've had spills. I'm wondering if the same process could be applied where we could heat up, say, the sludge mixture of the contaminated soil. We could basically melt off the oil that's there, and that would be a kind of environmental cleaning process. That could be followed up by the technology that Mr. Gradek is proposing through his process. Is that something that could be used?
If you look at it from a technical perspective, the oil companies are simply cleaning the oil out of the sand and putting the sand back into the tailings pond and it's settling out. My understanding of the technology that Mr. Gradek is proposing is that it will actually get rid of the remaining bits of bitumen or oil in the process that are interfering with the ability of the settling in the tailings ponds. From your perspective, are there applications of this technology that we're not even looking at in this particular point of time?
