I jsut wanted to comment that most of what is being discussed here has already been invented before and neglected by the car industry. It is really a shame and makes one wonder deeply about the true motivations of the car industry. What strikes me more is that the increases of efficiency and fuel combustion mentioned in this article have been deemed imposible before when independent inventors have made claims about that.

But what enrages me more is that since the advent of computerized and electronic fuel injection for cars, the possibility of independent control of the valve timing has been just a matter of engineering, and have to wait more than a decade to see it being claimed as a breaktrough, I have no words for calling this. They are laughing in our faces!!!
