I certainly think there is tremendous opportunity for innovation, but I do think we now have a history that shows that innovation is spurred by regulations, financial incentives, and a variety of different policy measures.
This is what we're seeing now in the world, for example, in the renewables area, particularly in photovoltaics. Because Germany and Spain and the U.S. have had rigorous renewable regulations, if you will, and financial incentives, we have a very vigorous photovoltaic industry in the world that is driving down cost with new technologies. Margins in many companies have fallen for a variety of reasons, but I think we have a good example there where policies have spurred innovation.
