If the overall goal is to reduce the cost of driving a good sized diesel truck, I'd consider Biodiesel. You mentioned having a ready supply of manure. What produces that, and what do you feed them? |

Cattle, Sheep and Hogs. We feed them Alfalfa, Corn Sileage and other grains. The process of making fuel from these feeds, is out of our reach. Cellulosic Ethanol isn't something that is easily made in your back yard. Mark |

There are a number of seed-oil crops (like this one) that make good sources of vegetable oil for fuel, and the residue from pressing the oil is still usable as feed. |

Nobody grows rapeseed in this part of the country. I will have to check into it. Also, Blackleg, a disease which has been nearly eradicated in this area, is prone to a comeback if people start to plant rapeseed here. Mark |

I guess you missed the word like. There are other fuel-crops. |

If the overall goal is to reduce the cost of driving a good sized diesel truck, I'd consider Biodiesel. This post of mine, some 7 posts ago, covered this precise subject It's good to be back amongst friends and colleagues |

If the overall goal is to reduce the cost of driving a good sized diesel truck, I'd consider Biodiesel. Interesting prospect there. I wonder what it would cost to get it all set up? Mark |

It's not just the H2 and O2 it is the compounds in the fuel and the compounds in the air that will be formed when diesel fuel plus its additives plus the compounds in the air and the reactions that happen when they burn under compression and then adding more oxygen and hydrogen to the mix making more complex compounds such as nitrogen oxides and sulphur compounds and then adding more oxygen and hydrogen to the mix will produce gums and sludge and other pollutions because of the compounds in diesel fuel. Now just a pure hydrogen fuel car would produce water and that is a hydrogen fuel cell or switch to propane and it can be used indoors and in sensitive areas like the everglades but to add diesel to the mix and all kinds of compounds will be produced leading to pollution and gum and sludge. The Nitrogen and it's oxides will still be a problem with diesel and the H2 and O2 additions a severe source of pollution and how the extra H2 and O2 reacts with the compounds in the air as it mixes with the fuel as it burns under compression. Any ideas on that? |

Any ideas on that? I cannot be definitive on that statement (NOx is a problem). Diesel burns much hotter when combusted, which gives it more power but allows the nitrogen in the air to combine with oxygen in a complicated way to form various NOxes. However, in Europe it is not a massive problem due to exhaust gas recirculation to cool the combustion, and cars with urea exhaust catalysts to mop up the rest of the NOx. Indeed, petrol power is now producing more NOx and particulates at the tail pipe than diesel. It's good to be back amongst friends and colleagues |

If the overall goal is to reduce the cost of driving a good sized diesel truck, I'd consider Biodiesel. Growing Rapeseed and using it for oils, then using the leftover products as feed, might be a good option. I will have to check into it. I do not know what kind of processing equipment will be necessary to get the oil out of it though, and the information didn't jump out at me the first time I looked at the website. It might be a really good option. Mark |

If the overall goal is to reduce the cost of driving a good sized diesel truck, I'd consider Biodiesel. Mark, You basically need an oil press. You take your oil-seed and feed it into the hopper. The screw in the press squeezes the seed, oil comes out one port and the residue "cake" comes out the other -- and goes to feed livestock. You can modify your truck or other equipment to run on the seed oil, or you can do the chemistry and make Biodiesel. -- Ned |

If the overall goal is to reduce the cost of driving a good sized diesel truck, I'd consider Biodiesel. This Wikipedia article describes other feedstocks, including sunflower and soybean oil. |

open Questions Why has the technology for electric cars been stalled Why is research into hydrogen gas as a fuel actively discouraged Why is the price of fuel so high when there is no need for this price according to the Saudis who are pumping oil flat out. Are we all simply prepared to sit back and take this "bull" from the companies who are acting more like gangsters every day that passes... comments welcome |

Its not easy to answer. VW will release two hybrid cars by the end of the year. BMW and Mercedes are working on HH0 cars. But its all about money. How could the market make money if you could fill your car in the garden just with water. Million of companies could close their doors. And million of people would be workless. With each crime and every kindness we birth our future. |

... Why is the price of fuel so high when there is no need for this price according to the Saudis who are pumping oil flat out. The 'cost' of fossil fuel is set to go very very much higher... There is the 'discounted' cost of polluting the atmosphere with vast amounts of CO2 from burning all that oil. Far earlier than ever imagined, we've got a 50:50 chance of there being no ice at the north pole this year. No ice at The North Pole North Pole May Be Ice Free for First Time This Summer And if you shrug that off as nothing or 'natural', then sorry but you're not on this planet! Perhaps the recent speculative increases in oil prices are the best thing ever to have happened to push into using non-fossil fuels.

Its not easy to answer. Peugeot is also bringing out a diesel-electric hybrid, like Mike states VW will be doing so. The loss of ice at the North Pole in the Northern Hemisphere's summer is interesting. This means the North Polar region will be returning to it's ice free nature, like it was about 1 million years ago, but sooner than expected. It's good to be back amongst friends and colleagues |

The 'cost' of fossil fuel is set to go very very much higher... And yet, you think it's OK for China, India, Russia, and Mexico and anyone else to burn as much as they wish--you think that so much so that they get EXEMPTED from any limits. They love that. They burn as much as they want, get a a scapegoat out of the deal, and people like you support that. And, best of all, total emissions never get cut a whit. What a brilliant plan. Far earlier than ever imagined, we've got a 50:50 chance of there being no ice at the north pole this year. Welp folks, you heard it here first. We're all dead. Perhaps the recent speculative increases in oil prices are the best thing ever to have happened to push into using non-fossil fuels. And, if the clamor over high energy prices is any indication, or the way people waste resources with crunching and "farms" and posting incessant and inane pictures, you can see how people really aren't going to cut much, no matter what you want them to do. Which brings us full circle again--you had better come up with some better ideas than you have so far, or we're all going to die. Probably by December.

open Questions Because electric cars aren't as non-polluting as most would have you think. It starts with power, because somewhere, something is generating the power, and it's probably gas, oil or coal. Then transmission losses, and finally, when the batteries are done they're toxic waste. It moves the pollution problem (and the fuel problem) from the car to the power plant. Oh, yeah, don't forget charging time. ... and hydrogen isn't really a fuel -- it's a transport. You make energy (electricity) someplace, electrolyze water, take the hydrogen someplace else, and recover the energy by burning the hydrogen. Great idea, but it moves the fuel problem (and the pollution problem) from the tailpipe to the power plant. According to this article, prices are up because of production cuts by OPEC, especially Saudi Arabia. It's a dangerous game -- when oil is $30/barrel, it's hard to create new technologies, infrastructure (Hydrogen, CNG or "electric" stations) and make a profit. At $143/barrel, those options become much more attractive. |

The car companies don't care about "the market" in general. They're in the business of selling cars. High fuel prices are an opportunity to sell fuel efficient cars. Low fuel prices are an opportunity to sell bigger, less efficient cars. Respond to (or predict) the market correctly, and your car company will do well. If that means filling your car from the garden hose, great! The problem is that water does not burn. You have to do something to make "fuel" out of water and that takes energy -- which you end up buying somewhere. |
