Hmm, this is only indirectly related with diesels, but in any case it is a promising piece of news that deserves to be followed up. "A Spanish research team has reported today that it is successfully developing a process in order to efficiently produce petrol from algae. Such a process will consume atmospheric CO2 instead of 02. The end-product should be gasoline, diesel fuel, kerosene, plastics, etc... even coal." We will see, cautiously thoug with hope. Regards, Jose |

The increased use of dead animal fat will then produce an additional up stream demand that has the effect of increasing the marginal rate of profit of animal production and therefore increase production itself. As producing animals for any purpose creates an additional demand for animal feed, this development will also drive that demand. Any increase in the growing load on the available farm land increases the cost of food for all consumption, animal or human. It will concomittantly increase the the use of water, which is in increasingly short supply, and also that of fertilizer which is largely fossil fuel dependent. Additionally, feed lot methane production, a green house gas, will be increased, ground water pollution from animal waste and chemicals, now down to the third level aquifers, will also become worse. The poluted water will become increasingly more costly and energy dependent to clean up, to the extent that it can be at all. I am sure that the corporations, who are the chief beneficiaries of this diesel petroleum scheme, will be more than happy to address the un-recognized costs of their enterprise. And that is only the tip of the ice berg. There don't seem to be any free lunches. |

Just let diesel models be available, let them get 30-40% fuel economy over like unleaded regular models. This uses less resources than unleaded regular and even less resources compared to ethanol. The cost per mile driven is easily 20-40% cheaper. If you want to accelerate the changeover to diesel, cut the tax rate, volume and %. This is FAR too sensical and logical, which translates to political impossibility. Of course there is hydrogen. A Civic sized car gets all of 22 mpg. Current price of hydrogen per gal WEIGHT= 18 dollars per. |

quote: German auto supplier Behr GmbH & Co. KG today introduced three parts at the SAE 2007 World Congress that the company says will reduce emissions and improve driver comfort in diesel-powered vehicles. They are: 1. Positive temperature coefficient heaters, which enable vehicle heating systems to emit warm air the moment the key is turned. 2. No-idle air conditioning, which enables vehicle air-conditioning systems to operate with the engine turned off. 3. High-volume exhaust gas recirculation coolers, which help reduce the amount of oxides of nitrogen, or NOx, produced by diesel-powered vehicles. -end |
