Well, as you know, government has subsidized so many things that of course a few things will have succeeded, but I would argue that in the cases I showed you there, the funding was entirely private. Again, I have no doubt that if things really are more efficient, if new technologies look more efficient and have a reasonable promise of earning you a return on your investment, private investors will risk their own money and will fund them. I have no fear of a capital shortage in that respect.
