Can you speak to the competitiveness of solar and to the way it can help with the integration of renewable energy sources? Right now, whenever people talk about solar the image in people's brains is just that from solar you get electricity. Actually, though, there are other ways of using solar power. For example, some people use solar energy to melt salt, and they use the molten salt to heat other things—water, or whatever—to provide heat sources.
Can you also comment on the potential of these kinds of technologies?
