[Biofuel] Petrol wields profit, but it also kills
Petrol wields profit, but it also kills *When it comes to energy, economic and geo-strategic interests generally determine the course of European politics. MEP Alain Lipietz asks whether politicians will give the environment a chance* Alain Lipietz, member of the European Green party and ex-French presidential candidate, analyses the decreasing availability of petrol, the development of renewable energy sources and the role the European Union will be expected to play. *Does the European Green party deem the increase in the price of petrol to be a positive thing?* Yes, in the sense that it encourages people to watch their consumption of petrol. But it is not the best solution to the problem: it would be of much better use to increase public awareness. There comes a point when we need to send a strong signal. It would have been better to levy a strong eco-tax during the last decade when the price of petrol exported by the Organisation of the Petroleum Exporting Countries (OPEC http://www.opec.org/home/%20) was low. Whilst maintaining stable prices for consumers, taxes could have been used to finance research or equipment which saves energy, such as public transport. This chance was missed ten years ago. Without these technical adjustments, both industrialised and industrialising countries are now completely dependent on petrol. For various geological and geo-political reasons (Iraq, Russia, Nigeria), the availability of petrol is significantly decreasing. As a result, its price is currently skyrocketing and the repercussions of the lack of political action are being felt. But every cloud has a silver lining and this [price surge] might actually push people to start saving energy. *Does the current crisis present us with an opportunity to develop renewable energy sources?* There are three possible responses to the high price of fuel. The first is to ultimately cut down on consumption, by driving more slowly for example. The second one, and this is where the price warning comes in, is to increase the economys efficiency in energy handling; such things as cars, factories, light bulbs and so on should waste less energy. Finally, our third response could be to actually change our sources of energy. It seems obvious that the more expensive petrol becomes, the more appealing renewable energy will seem. However, this is not enough: petrol is still cheaper than some renewable energy. *In that case, should we wait for renewable energy to become profitable?* We might not have to. The European Union has already recommended that 21% of our energy be renewable by 2010. However, this measure has no constraining value. Some member states, like Germany, Denmark and Spain, fix a very high price on electricity produced by renewable energy (wind, biomass, etc.). This means they have to be subsidised. The several dozen wind turbines in France are still very expensive, whereas a few thousand of them would cost much less. These countries are effectively kick-starting the process: they start off by subsidising in order to support large-scale production that will be profitable in the long run. *What are the issues at stake when it comes to abandoning petrol?* New industries have begun to explore this area. Some electrical companies in Europe seem to have grasped that the future is set to be the age of renewable energies. Germany, Denmark and Spain have developed an industry dedicated to equipping sources of renewable energy. France, on the other hand, seems to stick to looking to dangerous nuclear technology as a means of energy independence from petrol. Indeed, EDF [the main French electricity company] has supported neither the wind turbine nor the geothermic industry. Vested interests of big industrialists in every country continue to weigh heavily on the electrical production infrastructure. *Are you concerned at all about the risks the reduction in petrol consumption would involve for the development of the oil-exporting countries?* I am President of the European Parliaments Delegation for relations with the Andean Community http://en.wikipedia.org/wiki/Andean_Community%20. As it happens, the five member states produce petrol: Venezuela (a big producer), Columbia, Equator, Peru and Bolivia. For these countries, the consequences are substantial. When petrol prices are relatively low, they cancel research contracts and remove all chances for academics to travel and so on. In Venezuela, 80% of state income comes from petrol. For years, Ive told Venezuelans, You are a big exporter whose income rests solely on petrol; but at the same time, you are the first victims of global warming, what with all this torrential rain causing thousands of deaths. Today, Venezuela is the first big exporter of petrol to have signed the Kyoto Treaty, because even though petrol wields profit, it also kills. For next April, we have organised a colloquium there in order to construct a Euro-Venezuelian alliance on petrol costs. Considering its

Part:1 Thanks Max, that is really enlightening. I'm looking forward to your next email. Christopher Hello Christopher, and all ! PART: 2 My own solutions As in the commercial kerosene cars (Saab and Talbot), I made a preheater for the kerosene, from the coolant circulation. Further more, I installed a starting gasoline tank, and an electric fuel pump for the gasoline, operated with a flip switch at the dashboard. At the carburettor an electric (magnetic solenoid) valve for choosing fuel, with a flip switch on the dashboard. The standard (mechanical) fuel pump delivered kerosene from the old gasoline tank. In the first car I wrapped in BOTH the exhaust- and the intake manifolds in the same package made of peaces of aluminium sheet, about 1,2 mm thick. The package was tightly screwed together with self drilling sheetscrews, air was taken in from small slots towards the engine top. From a peace of thin metal tube (65 mm diam.) I made a stud, screwed to the aluminium package. Attached to the stud, an air hose (diam 70 mm) transported the intake air from the package to the enlarged air filter intake. On the air hose I had a slide valve, operated by wire from the dashboard. With this valve one could blend in cooler air, when the engine room got hot enough. The temperature of the intake air was read by an electric meter on the dashboard. The thermal sensing device was bolted through the air cleaner cover. Water nebulisation was made by an identical carburettor, attached on top of the fuel carburettor. To avoid too great amounts of water, and too much of air choking, the air venturi was removed, and the main fuel orifice had to be prepared, so that the flow area would be decreased to a fourth of what was used in the real fuel carburettor down beyond. Both carburettors were of one-throat type; small engine. The increased (air)flow area in the water carburettor had the desired result, that no water was nebulized at idle RPMs. Under load, the water consumption kept around one fourth of fuel consumption. This was enough to avoid knockings, and keeping the combustion chambers free from soot and slag. Still, this amount did not cause any noticeable washing of the intake valve stems, the lubrication was functioning properly. The float chamber in this upper water carburettor operated without ANY FLOAT! The water tank was placed in the front passenger's foot compartment, about half a meter below the carburettors. Around the bottom, inside the tank, a circling copper tube melted the ice in the winter, with valve-regulated hot coolant, in 15 minutes. On top of the tank, the water pump (24 V) with a vertical shaft down to the tank bottom, where the centrifugal pump. (Originally a windscreen piss-pump) At 12V the pump, now with 2-fold thicker coal-brushes for constant use, gave a water pillar (gauge) of 1m. This was enough to fill up the float chamber trough a 1 mm orifice, horizontally to the BOTTOM of the camber. Bottom, while it should DRAIN the chamber back to the tank. No ice in the chamber, when freezing! A second (6 mm) hose was taking care of the overflow, starting from the chamber side at the desired height. Sloping back to the tank, it suctioned a string of air bubbles, more or less, according to need. The level was always constant. The second car was othervise arranged in the same way, but I made the mistake to leave the intake manifold outside the aluminium wrapping. This forced me to use higher temperatures on the intake air! (100 - 110¡ Celsius, instead of 90 - 100¡ Celsius) It works better to have hot intake manifold SURFACES and modest air temperatures ! This will put the RELATION between nebulized fuel fog and fuel dry gas just RIGHT ! Haven't you observed it with gasoline-carburettor cars? When the engine room is almost too hot: The motor moves softly as a cat at low RPMs; like a steam engine, and gives good torque, without tendencies to stop? A slightly cool engine room and engine, is very much prone to stop on low RPMs, if you try to get torque, as when parking in deep snow? REASON: Dry fuel gas burns slowly, and fuel(micro)fog burns more like an explosive, but is harder to ignite (as cool). Another difference was, that the second car had a double throat carburettor, so the water nebulization had to be made in the same carburettor. Where the fuel arrived to the air venturi from the front, the water arrived at the same height from the rear. Same arrangement in both throats. Throat no:1 got two levels of water supply by mixing in a small amount of bleeding air in the waterline from the (external) float chamber without a float, determined by an air valve, operated by a spring-loaded diaphragm, which sampled the intake manifold pressure (vacuum

PART: 1 As Petroleum was found about ~150 years ago, one of the first uses was to distil lamp kerosene for lighting. ~100 years ago they started to distil motor kerosene, a distil fraction about 110 - 130¡ Celsius. This was before the Diesel motor had spread into larger acceptance around the world. (And the patents of Rudolf Diesel and MAN had run out). Lamp kerosene is a few fractions higher, and does not include but very little aromatic components, to be able to use it indoors. Motor kerosene, on the other hand includes far more aromatics and light volatiles, which can be recognised by its sweet-sour smell, when burned in an Otto motor. Until the '50ies, motor kerosene had its natural low octane value, and did not allow higher compression ratios than ~5:1. Compare Fordson tractors' 4,5:1 as well as boat motors. Modern motor kerosene was beefed up with lead (MBTE?), and allowed a compression ratio of ~7,5 : 1. One cannot start an Otto motor on motor kerosene, unless the motor is at least 60¡ Celsius. A cold motor has to be run warm on gasoline (petrol), before turning to kerosene. Motor kerosene has NOTHING to do with ANY grade of DIESEL FUELS ! (The nearest comparison would be aeronautic kerosene !) Despite this, some taxi drivers used to mix ~15-25% motor kerosene in their diesel fuel in the winter back in the '50ies and '60ies, before the WINTER GRADES where developed. But this was just an attempt to handle the PARAFFIN FALLOUTS, which stopped the fuel flow by clogging the lines and filters! The winter grades are deprived of sublimating paraffin, so the clogging is not a problem any more, to about -35¡Celsius, (POLAR GRADE goes still further). Now, about car use: In Finland it was allowed, for a brief period, between ~February and 30.6.1982, for a private person to re-register gasoline driven cars to be driven on motor kerosene (paraffin). At that time, two car factories did market motor kerosene driven cars in Finland. (Saab and Talbot). The monopolistic law protecting these factories, was turned over in the beginning of the year 1982, but the parliament re-wrote the law again in May, coming in force from 1.7.1982. Both these commercial car models for kerosene, had their intake air pre-heated by a motor coolant heating element (heating battery, like the heating element for the passenger cabin).

[biofuel] Petrol Station Leukemia risk
Just found this interesting article: http://uk.news.yahoo.com/040819/12/f0pow.html which discusses a study that indicates an increased risk of Leukemia for children living near a petrol station. It suggests that it's due to the benzene in the petrol. Yet another nail in the coffin of mineral fuels maybe? Or perhaps more like another growth ring on the tree with which the coffin will eventually be made. Full text below. Donald Leukaemia risk for kids living near petrol stops By Gaia Vince Children who live next to a petrol station are four times more likely to develop acute leukaemia than other children in the same area, suggests new research. The small study, carried out at four sites in France, looked at 280 children with leukaemia and a control group of 285 children, all younger than 15 years. The childrenåâs mothers were given a questionnaire relating to their lifestyle. The researchers found that children living next door to a petrol station or automotive garage had a quadrupled risk of leukaemia. And the risk of developing acute non-lymphoblastic leukaemia was seven times greater compared with children who lived in the same area, but not next to a petrol station. åãI was very surprised that living near a petrol station had such a high risk,åä says Jacqueline Clavel from the National Institute of Health and Medical Research in Villejuif, France, who led the study. åãThe longer the child had lived in the vicinity of the petrol station, the higher their relative risk was. Prenatal exposure also raised the relative risk.åä Rubber factory Clavel suspects benzene in petrol caused the rise in cancer risk, although she says further studies need to be done. åãThe link between benzene and leukaemia has been shown for workers in a rubber factory, but the benzene levels are very high in that instance. Exposure to benzene is much lower for children near a petrol station, so it was surprising,åä she told New Scientist . Richard McNally, from Cancer Research UK's paediatric and familial cancer research group, says that while the findings are interesting, they should be treated with caution. åãThe study examined a relatively small number of leukaemia cases, and the fact that it was based on interviews leaves it open to influences such as inaccuracy in the recollections of the mothers interviewed,åä he says. Although it is the most common childhood cancer in the western world, acute leukaemia is rare, with four new cases per 100,000 children each year. The majority of cases occur in two-year-old infants, but more than 80 per cent of children make a full recovery.

James I have not got any personal experience but there has been a fair amount of discussion at both the Infopop and the Goat Industries forums - linked from http://www.vegburner.co.uk/links.html - do a search at the forums. From what I've read it appears less petrol is required compared to diesel.

From what I've read it appears less petrol is required compared to diesel. Problems have been encountered running petrol/SVO blends through fuel pre-heaters, the petrol will vaporise at the temperatures SVOers normally try to achieve causing similar problems to air leaks. There's a guy on Infopop, who goes by the handle Kugelsicher, that is running a Ford F-250 on a mixture of 80% peanut oil, 20% gasoline, and a bit of PowerService Diesel Fuel Conditioner. The only change he's made to his truck is that he looped the fuel return. Last time I looked, he was claiming 8000 miles on this mixture without any problem. He mixes his fuel in batches of 40 gallons WVO, 10 gallons gasoline, and 1 quart of PowerService. The stuff has to be mixed vigorously or it will separate, but once mixed it forms a stable mixture. I might try this as a stopgap measure until I get my 2 tank system installed, but I really don't like the way gasoline smells.
