Here's how the final chapter, "X Cars for Cleaner Air," ends:
Ten years ago it would have been difficult to imagine a town or city business section without automobiles on its streets. If we want to continue breathing, we will have to begin to imagine it because it will probably come to pass ten years or so from now -- unless we succeed in finding ways to eliminate the air pollution caused by gas-burning automobiles such as those we are driving today.
That is the challenge our X-car engineers face. They have never faced a greater one.
Three decades later, industrial hemp, an efficient, clean fuel source, is still criminalized by those dopes in Congress.
