Tetraethyl Lead was used as anti-knocking additive to petrol. In Brazil we add 20% Ethanol -made out of sugar cane- to gasoline so that we didn't add Tetraethyl Lead and save in oil import. ww2.green-trust.org:8383/2000/biofuel/dwg/dwgch2.htm

Land could be used to grow bio-mass plants to 'sink' CO2 off the atmosphere, to offset the C02 liberated by combustion engines.

EP, regarding ethanol in petrol [gasoline for Americans], it's just a matter of dollars per joule. The reason ethanol makes any cents for farmers and others in the supply and consumption chain is that governments punish fossil hydrocarbon producers and reward farmers. Government people and their greenie supporters think they are doing well for the environment by cutting hydrocarbon consumption and increasing alcohol consumption. I say use the cheapest source of fuel first. That's crude oil from Saudi Arabia, Iraq and Iran [and other low cost producers]. The amount of CO2 emitted is not reduced by using ethanol. It's increased. That's because there is a lot of energy used in producing ethanol, which means fuel burning. Tractors, trucks, fermentation and other processes all need steel production [steel mills use heaps of hydrocarbons] and fuel [more hydrocarbons]. I'm sure there is a net increase in CO2 emissions with increased alcohol use in fuels. It's greenie religion. It's simplistic dislike of multinational oil companies which motivates them. Which is stupid. Burning fossil fuels is long cycle recycling. They should love it. Without the demand for hydrocarbons, they would be left in their fossil subterranean graveyards until tectonic activity let them back into the biosphere, where they belong. The planet has been dying for eons. Ice ages have been increasing. We are bringing all that fossil hydrocarbon back to life. Saving the world from becoming a frozen waste. That's a good thing, though polar bears would disagree as their range is dramatically increased by ice ages moving the interface between ice and water nearer the equator. Mqurice
