"If you want to experience the depth of problems caused by (dirty) diesel exhausts, you need to visit a city like Manila on the outskirts of which I live. All the busses, trucks, and medium-sized people-movers are diesel powered as are about half the private vehicles. (There are also many 2-cycle motor tricycles.) Here, the level of infant asthma is staggering - something like 60% I was recently told by a pediatrician. I don't have any figures for lung cancer and, with a nearly non-existent public health service, there probably are few accurate statistics available. On a subjective basis, I have seen visibility on an otherwise
clear day reduced to 50 meters or less by concentrated diesel exhausts. People walk the streets with handkerchiefs over their faces much of the time. If I travel into the city for a day I cough for three days afterwards. Now, if adding a percentage of biodiesel could alleviate even half of these symptoms, it would be very well worthwhile.
One problem, in countries like the Philippines, is the low cost of fuel. It is currently around 30 cents US per liter for 'high-sulfur' diesel and no government has the political will to enforce higher fuel quality or lower emissions, either of which would be perceived as lowering the standard of living. With the price of petro-diesel thus pegged, it is difficult to imagine how bio-diesel production could be sustainable. All suggestions gratefully received!"
got this from another forum..
