Where does the technology stand today, in 2007? The research service document stated that the Cummins diesel engine firm perhaps had doubts about the capacity of current engines. I know we can use biodiesel, biofuels, but there may be doubts as regards longevity, and so on. Does the current technology allow us to think that... With the program that the government has put in place and what's happening in other countries, such as the United States and Brazil, we use an enormous amount of biofuel. I imagine that the engines' efficiency is proportionate to their longevity, but I'd like to hear your views on that.
