The one I like and think is so funny is the used (French fry) you may not know what I'm saying but just frying grease (for food) in industrial use. They strain it and maybe any oil will do but anyhow they use it in diesel powered vehicle's. Some get it for free.

Just brew your own biodeisel which is perfectly legal providing it's under a certain amount and is just for personal use.

I was kind of slow to catch on, but in retrospect, growing what otherwise might be fit for human consumption (or at least growing it on land that might otherwise be used to grow produce that would be fit for human consumption) just seems like a bad idea. There was something on the news to that effect last night, remarking on how the food shortages in Senegal were compounded in part by the competition for farm produce as a fuel source. Clear land, grow seasonal crops on the land, to effectively produce more greenhouse gasses? Seems like a bad idea to me.

Grow more food for people, not cars or animals, and teach contraception without practicing eugenics. We can find a cleaner, more sustainable, and holistic solution than biodiesel, unless biodiesel can be incorporated sensibly into the food-for-people-first equation.

Although I don't believe in so called 'Global Warming', I must say that producing ethanol fuel DOES NOT produce any extra CO2. The carbon dioxide that gets released by burning the fuel in cars was simply caught from atmosphere when the plants that were harvested for the fuel grew. The same idea lies behind biomass.

That is the same reason why wood is considered a clean and renewable source.

You're grossly mistaken about the process of refining ethanol from vegetable matter.

You're wrong. While living, most plants will continue to result in a net product of oxygen and a net deficit of carbon dioxide into the atmosphere. Once you burn them, they produce a lot of carbon products, and their ability to contribute any oxygen is severely compromised.

That might be true where you are (I don't know), but it's not true here. Mike Holmes is regularly demonstrating better and stronger alternatives to traditional wood products.

Jay.slovak

Yes there is some release of carbon dioxide from the production, no doubt about that. But I was comparing to the 'traditional' ways of producing fuel (from crude oil), they should have about the same processing releases, what is different is the source, living plants versus trapped carbon (in oil).

You need to take into consideration what's being used to produce the ethanol. In Canada, it's mostly corn. Then you need to look at what's being displaced to grow the corn. In Canada, for ther most part that's trees and wetlands. Then you need to compare the oxygen/carbon dioxide converson capabilities of corn vs. the natural ecosystem (with all its various lifeforms, including animals) displaced. Corn is almost invariably the loser when it comes to providing oxygen. So you cut down a great machine for converting carbon dioxide to oxygen most of the year (e.g. a tree) to grow a few plants that you'll drive over with a tractor after a relatively short growing season.

Oil from the ground is arguably a better solution than this bio-ethanol consideration, even though I hesitate to admit that burning any oil is a reasonable solution to anything nowadays (it's just the lesser of two evils). On the surface, vege-ethanol can be sold as a hippie-friendly solution to a problem that's been characterized as evil. Underneath the surface is the nightmare of having oil companies own your country's land, destroying your environment, and inhibiting your capabilities of providing food for nations needing assistance.

I guess there is a wild grass that grows and is common in the mid west here in the U.S. It may provide the necessary ingredients for making fuel and will be more Eco friendly on all sides. They are still trying to find a better way to break it down to start the process. Harvesting the greater part of the mid west here will be encouraging for farmers.

The oils are mostly triglycerides. A triglyceride has a backbone of glycerol (3 alcohol groups on a 3-carbon chain) and to each alcohol group a fatty acid is esterified. The triglycerides are "brewed" with alkali and methanol to give the methyl esters of the fatty acids and glycerol. The glycerol by-product is often used for making soap. Biodiesel consists of the methyl esters. John

Prices at the pump yesterday here in Adelaide

Unleaded $1.56.9 a litre
Diesel $168.9 a litre
Autogas $0.69 a litre

I think its 3.58 USD per gallon over here in Lexington, Kentucky.

rjvh

in cambodia the prises are $1.22 premium $1.20 avarage $0.98 for diesel

cooking gas botle (15kg) last month $17.8 this week $36 is aspected to come down to $29 (prime minister (dictator) had some hard words and threads for the speculators in this game (2 months before election time))

price of electricity is $0,21 a Kw

avarage income is $70 a month, efectifly this is higher for a lot of people deu to coruption income but still a lot of people in the country side have considerably less

In my part of Canada (Canada is huge and the prices for gas are different across it), regular 87 octane is $1.07.2/liter today. The most expensive is 94 octane and is used by the little kids that burn out their engines and tires.
One week ago a liter costed about $1.00. Up, up, up she goes.

Here on the west coast gas is about $1.27/L in Canadian dollars. Our dollar is 0.99USD so about the same. The C$ bobbles up and down daily, but averages par with the US$ for the last few months.

Regular octane number is 87.

Diesel costs about $1.49, 20 cents higher than regular. I'd rather own a diesel in New Zealand!

Smokes $9/pack.

Electricity .07/KWH. At that price, I'll keep the incandescent light bulbs. The warmth of the bulbs is not wasted. The bulbs emit heat and therefore help the furnace to heat the house. The furnace then cyles less. No energy is wasted. If I were to switch to CFLs, I'd have to pay for more gas to run the furnace. NG energy costs the same considering the efficiency of the furnace. I might save slightly during the summer using CFLs, but we don't need as much lighting in summer,- the days are long and the nights are short.
