In order to boost efficiency, this is blended with natural gas and converted into 10 kilowatts of electricity per hour." How much natural gas is added? What's the blend? If we take the entire 10kWhr as due to the seaweed, that's $1.40 worth of electricity per ton. Seems like a pretty low yield, and one wonders whether more than that was spent processing the stuff. Grinding up, pumping, collecting... Alas, there are no easy answers. Cheers, James |

Cheers, James- Hide quoted text - - Show quoted text - Not sure if these numbers are right, but from this website it looks like giant kelp is worth 5K to 8K BTU per pound, or maybe 2KwH which would be 28 cents. So, a ton of seeweed would be worth 2000 * 0.28 = $560 ??? http://www.osti.gov/energycitations/...sti_id=6868993 "Examples of biomass that may prove to be optimum crops include land crops of Sudangrass, napiergrass, sorghum, sugarcane, and the unicellular algae Chlorella and Scenedesmus, and seawater crops of Macrocystis pyrifera (giant kelp).^Several of these crops could yield 20 to 30 tons of dry organic matter/acre/y, some others up to 60 tons/ acre/y.^These crops are estimated to range in fuel value from 5000 to 8000 Btu/dry lb " -Bill |

My current ride gives about 32 to 35 mpg commuting, but it is overpowered and very quick and fun to ride. (110 HP on 800 Lbs curb, full tank.) I drive a Jetta TDI, it gets over 50mpg on average driving. Since it runs diesel and prices have been so absurd, I have been in the process of building a small biodiesel refinery. It's a pretty simple solution and as I'm calculating it, parts should pay for themselves in about 6 months, after which I should be able to produce BD well under $2.00/gal easily. I live in the US (go figure) where really only two manufacturers produce cars using this technology (no domestic producers). The country has made serious mistakes on their alternative fuel planning: 1. For instance, tax credits are given to those who drive hybrid cars WHICH still burn gas (or at best 85% ethanol), and are hardly as efficient on highways as their diesel competitors (which can run 100% biodiesel). No tax credits are given to those who drive TDI's which are more efficient outside of cities and can run on pure biodiesel. 2. Biodiesel is shown to produce cleaner emissions, with the exception of more NOx production (which by the way can be controlled due to the lack of sulfur in BD). Unlike ULSD diesel, BD protects the engine better. It also benefits farmers in the country and slows the the bleed that continues (and will continue) in the US economy due to its reliance on foreign exports. The only real downside with BD is that it does not have a high tolerance for extreme cold, but most of the country could still be shifted to it (the rest could have smaller amounts blended in). 3. Ethanol on the other hand has been shown to have a short shelf life, is extremely corrosive to many materials, and has poor efficiency. And yet the government mandates it get added to fuel to decrease efficiency some more and increase the demand for imports. 4. The EPA has made it nearly impossible to produce diesel engined cars in the US, rather then trying to mandate a shift to BD blends and encouraging the production of more efficient cars, it continues to block them out of the market citing emissions. Consider if a diesel car puts out 20% more emissions, but gets nearly 40% more fuel efficiency, isn't there actually a net loss of 20% emissions. No, the EPA has not planned a shift to an alternative fuel which works, it still is promoting ethanol, of which not much good is coming of it. The net fact remains, aside from some mass transport vehicles and fortunate rural areas in the west, most of the US relies solely on petroleum imports, and with current government policy, that's not about to change.

The only real downside with BD is that it does not have a high tolerance for extreme cold, but most of the country could still be shifted to it (the rest could have smaller amounts blended in). As soon as you start planting crops just to make biodiesel, its advantage is lost. Biodiesel from waste products adds value to the economy. Biodiesel from crops doesn't because it is all from seed oils which takes a lot of energy inputs to make. 3. Ethanol on the other hand has been shown to have a short shelf life, is extremely corrosive to many materials, Biodiesel also attacks many materials. |

As you say, the reasons are many, but one thing is for sure, petrol prices have had very little in the way of linear correlation with oil price. Dave. The popular price per barrel quoted in the news is the spot market price, and ignores the oil refined within vertically-integrated companies and oil delivered under long-term, fixed-price contracts.

Introducing large stocks into the open market will reduce the spot price. I don't think it really would or at least not by very much. If a vertically integrated company sells its crude oil into the market, it won't be refining it into finished products and selling those. Others will be making that finished product from the crude oil instead. The net effect won't be anything like putting new oil from a well onto the market. Long term contracts are set at a price point where both the buyer and seller think they will make money over the term of the contract. Yes and those predictions are based on the conditions at the time the contract is made. The next batch of contracts will be written in a very different environment. |

Planting for burning drives up food from supply *and* demand sides, plus all the downstream products--and in other countries--too. Unintended consequences: 1. Al Gore sounds alarm 2. biofuel craze 3. farmers grow feedstock for cars instead of people Results: 4. Human misery increased a. inflation, locally b. food becomes unaffordable in Mexico and Haiti c. people starve 5. Environment not improved a. replacement food grown, appallingly inefficiently b. net CO2 emissions increase I don't see 5b being true. The food plants is are replaced from carbon already in the environment. If this achieves any reduction in consumption in fossil fuels, then it achieves a decrease in transfer of carbon from the lithosphere to the atmosphere, biosphere and hydrosphere. Only if you don't slash and burn pristine rain forest to grow your new fuel and food which is what is happening in many places at present. Forest destruction is a one-time event for a given area. Having the land replace petroleum consumption with biomass burning will be replacement of ongoing carbon desequestration with neutral carbon impact. You lose on both sides of the equation, burning the forest and no longer having it there to do photosynthesis. By comparison the crops don't fix as much CO2 Where do you get that? A steady-state forest has zero carbon impact both locally and globally - the biomass content in a natural forest is not steadily increasing long term, but constant on a long term. Cropland sequesters carbon locally and if the crop is eaten, burned, decomposed or any combination of these, has zero carbon impact globally. and the poor soil quickly degrades without the forest canopy. That is a separate problem, to be solved by growing sustainable crops or growing crops where they can be sustained. The USA has a fair amount of farmland that could not be sustained until crop rotation including legumes was implemented. The economics of biofuel are questionable at best - some schemes actually use more energy from fossil fuel to cultivate and process the crop it than is yielded by the final product. You might as well not bother. What about the schemes that produce more energy than consumed? They do exist and are used! When we can turn straw and wood waste into alcohol for fuel then we will have something useful, but turning grain into fuel is certifiable. Impact on food prices is a remaining argument to consider. Meanwhile, corn is now $5.21-$5.28 a bushel, 9.3 to 9.4 cents per pound. With petroleum costing about 30 cents per pound and having much more energy per unit weight than corn probably by a factor of more than 3.2 or so, I would go along with arguments against government mandates to get corn to get used that way unless there is a benefit, such a likelihood that biofuel ethanol will be cheaper (even per unit energy) than petroleum in the foreseeable future. - Don Klipstein ) |

So say the paper's authors, anyhow. Cheers, James Arthur What about using kelp (seaweed) for bio-fuel? The ocean is cheap real estate and you don't have irrigation problems, mostly just transport problems. All you have to do is harvest the kelp and turn it into methane gas. -Bill Hi Bill ! 1.

Hey, here's an idea--why not just get *smaller* cars, and drive them *less!* That works with zero technical risk, current technology, saves money and saves the planet. ;-) Cheers, James- Hide quoted text - - Show quoted text - The Japaneese are working on the problem. Apparently, they can get about 20 milliliters of gas from a ton of seeweed. Here's a link: http://web-japan.org/trends/science/sci060824.html As for smaller cars, we could just ride motorcycles that get 100 MPG. But I was thinking the other day, it would be nice if the busses ran every 10 minutes along all the major roads. Probably reduce the traffic 80 percent, and we can always use a car if there's a lot to carry, or in a hurry, or afraid of motorcycles. -Bill So, do you ride a motorcycle? Or use buses or trains? How often? Don't warn him, let him get hurt and let him find the truth the hard way. I already checked with the motorcyclists. They said they're getting 28-30MPG on highway. There is no such thing 100MPG motorcycle. America loves to jump to conclusion on everything from Economy to WDM's. This time you're going to get hurt badly. You have not talked with a sufficient quantity of motorcyclists. Over time i have rode units giving anywhere from 22 mpg to 85 mpg. My current ride gives about 32 to 35 mpg commuting, but it is overpowered and very quick and fun to ride. (110 HP on 800 Lbs curb, full tank.) I drive a Jetta TDI, it gets over 50mpg on average driving. Since it runs diesel and prices have been so absurd, I have been in the process of building a small biodiesel refinery. It's a pretty simple solution and as I'm calculating it, parts should pay for themselves in about 6 months, after which I should be able to produce BD well under $2.00/gal easily. I live in the US (go figure) where really only two manufacturers produce cars using this technology (no domestic producers). The country has made serious mistakes on their alternative fuel planning: 1. For instance, tax credits are given to those who drive hybrid cars WHICH still burn gas (or at best 85% ethanol), and are hardly as efficient on highways as their diesel competitors (which can run 100% biodiesel). No tax credits are given to those who drive TDI's which are more efficient outside of cities and can run on pure biodiesel. For a great many drivers highway milage doesn't matter. Stop and go driving milage matters a lot for them since that is how the car is operated nearly 100% of the time. For many people a plugin hybrid would be the best answer. People who live in cities will benefit. But why have a car in the first place if you live in a major city? Why not use mass transit? I can tell you most of my driving is not constant stop and go, and I still live in the most densely populated state. 2. Biodiesel is shown to produce cleaner emissions, with the exception of more NOx production (which by the way can be controlled due to the lack of sulfur in BD). You can control NOx in with sulfur in the fuel. It isn't easy and it isn't cheap. Yeah, which is why the government went hellbent on mandating ULSD so cheaper systems could be implemented. Unlike ULSD diesel, BD protects the engine better. It also benefits farmers in the country and slows the the bleed that continues (and will continue) in the US economy due to its reliance on foreign exports. The only real downside with BD is that it does not have a high tolerance for extreme cold, but most of the country could still be shifted to it (the rest could have smaller amounts blended in). As soon as you start planting crops just to make biodiesel, its advantage is lost. Biodiesel from waste products adds value to the economy. Biodiesel from crops doesn't because it is all from seed oils which takes a lot of energy inputs to make. It keeps the money in the country and benefits farmers, the negative side is it increases some crop prices. I don't see how planting more crops for biodiesel spells a loss, I think if anything it would create a new industry in the US. The country has plenty of farmland, it might even be able to export if it can build the facilities. 3. Ethanol on the other hand has been shown to have a short shelf life, is extremely corrosive to many materials, Biodiesel also attacks many materials. True about that, I forgot it myself :P |

Exactly - Governments are not about change, but about preventing any! Governments are society's parasites adopted perfectly to the prevailing system so change is very risky to them because it creates a window of opportunity for a *different* set of leeches. I.O.W: Any energy scheme that reduces government income will not be supported in any way whatsoever and even sabotaged whenever possible. This applies in Denmark too! Joe |

Biodiesel from crops doesn't because it is all from seed oils which takes a lot of energy inputs to make. It keeps the money in the country and benefits farmers, Maybe not. If there is a free market in such things some countries nearer the tropics will have an advantage. Farmers rarely benefit from such things anyway. Folk like ADM get most of the benefit. the negative side is it increases some crop prices. I don't see how planting more crops for biodiesel spells a loss, If it takes more energy to product the biodiesel than you can get out of it, you certainly have a loss. Short of that you can end up forcing crops into land that is less suited to its growth and where more inputs are needed to produce the same food. The result can be more total energy. I think if anything it would create a new industry in the US. The country has plenty of farmland, it might even be able to export if it can build the facilities. If you look at the really good farm land vs just the farm land, you will see that the US doesn't really have a huge amount. A lot of the farm land in the US requires significant inputs to produce a crop. 3.
