Solutions that require increased complexity don't survive in the long run. I remember in the early '70s when my parents bought a new station wagon. This was right when the EPA was cracking down on emissions, and the manufacturers had to jump quick to compensate. Raise the hood on that thing, and you were greeted with a mass of hoses, pipes and components. Since then, lots and lots of work has gone into making clean engines simpler. Open the hood of a gas-powered car these days and you'll find relative simplicity.
