Thank you for your presentations. There's a lot of information in here, not a lot of words, but I think there's a lot more that you can add, so of course it's brought up a number of questions for me as well.
I too am concerned about sustainable development for the environment, for the economy, and for the social aspects as well. And you also talked about energy efficiency, and I'm curious, because you talk about the extraction process. What makes the steam get down there to extract the oil? What are they using to make the steam?
