This time, though, Mazda has outdone itself. The company just obtained a patent for a six stroke engine. What does it do with the extra strokes, you're wondering? It separates the hydrogen and carbon in gasoline so it can burn just the hydrogen, thus taking the carbon out of the system. Easy, right? No, not easy. And it gets even wilder from there.

It works like this: The engine makes hydrogen from gasoline using its own heat and a catalyst. It then burns that hydrogen and stores the carbon to be removed later. The result is that you can burn gasoline with zero CO2, at least most of the time.
