There are two areas. The first, as I mentioned, is the ecoENERGY renewable program. Solar is certainly eligible under that program for power generation. Its eligibility may be slightly theoretical, because to the best of my knowledge, it won't be competitive with other renewable sources.
There's also a smaller program that would support solar space heating applications, and there, I think, the economics are somewhat better. Then, in addition, through work in our own labs and through the ecoENERGY science and technology program there's an opportunity to provide research and development funds to bring the costs down and to make these solar technologies more economical and more competitive.
