Your questions are valid. I would use windmills as a comparison. Windmills were used, obviously, in Holland—the old Dutch windmills—and we used small windmills across the prairies and many places to pump water and generate a little electricity up to about 1950, when we put in an electrical grid, and then they were all abandoned. We thought that was the end of them. Then the energy prices went up and all of a sudden we started seeing people investing in them—Denmark, in particular. Now there are wind turbines—a new name branded. It's the very same technology, but with modern materials and modern designs, and they're generating income and benefits all around the world.
