At SDTC, I think we've shown over 10 years that supporting technologies that are good for the economy and good for the environment is not a contradiction in terms. They're actually synergistic. If you're developing a technology that saves money, that takes something that's a waste stream and turns it into a valuable commodity and a revenue stream, that creates a very strong business case.
We look at only those technologies that have a very strong business case, those that the market is pulling through. We talked about push and pull. It's appropriate in an academic setting to have the pull and the push. But when you get to the stage where SDTC is playing, we're looking for market pull. If there isn't a strong market pull for something, we won't back it.
So there's a natural synergy, because we have the customer or a supply chain partner in our consortium putting money behind this technology and saying, “This is strategic to our business. We're going to put our money into it to make sure it gets to market.” Well, how is that bad for the economy? And at the same time, we have measurable benefits to the environment. It's a core part of our program. So everything we back, we believe has both attributes.
