Andy, Andy, Andy, It's important to be PRACTICAL and REALISTIC rather than optimistic. Effective fuel cells in sufficient quantity to meet current needs are NOT 10-20 years away. They've been 10-20 years away for the last 50 years now. I'd prefer to think of them as at least 200 years away...

Andy, 1) Big business isn't opposed to clean energy sources. It's opposed to UNPROFITABLE energy sources. The equation doesn't work because we pay far too little for energy. 2) I don't know of any renewable (in the short-term) 'bio' fuel in sufficient supply and of effective cost usable by...

There's no money in it here Andy. Our sugar growers are small and marginal producers and resist selling up to large concerns. They have lobbied the government about ethanol production, unsuccessfully as it simply makes no commercial sense. The result would have been very large surcharges on...

Here's some information on the costs: http://www.usatoday.com/tech/science/2005-07-18-ethanol-study_x.htm Andy, Brazil is an isolated example and there are other factors at work (such as the government strategy and taxes on petroleum products, the ability of Brazil to grow the necessary...

Asy, Biodiesel is generally 80-90% diesel and the rest bio - so the saving isn't that great. Ethanol is a light fuel and not much use for heavy farm machinery. Neither produce as high an energy coefficient as petrol or diesel (meaning weight on weight they produce less energy per $...

Jym, A US gallon = 3.785 litres. Therefore the petrol (or gas as they call it) price would be between AU$0.65 and AU$1.15. Cheers, Aceyducey

Methane bubbles can cause recessions too :) Cheers, Aceyducey

I'm somewhere between 2 and 4 atm :) Cheers, Aceyducey

And up it goes again :) http://www.smh.com.au/news/business/gulf-of-mexico-storm-puts-rocket-under-oil-price/2005/07/07/1120704492612.html Interestingly there's minimal actual disruption of supply, simply the perception of potential disruption. And it's hurricane season! Oil prices...

Jym, Those fees add up to 65.425c .... And don't forget that governments also double and triple dip on the taxes as the oil passes through the process from pulling it out of the ground and refining it. They take a % at the well head (plus tax the company), more at the refinery, and so on...

Qaz, There's lots of different angles to the world oil market. What precisely do you want to investigate? Cheers, Aceyducey

No-one will forget the 'oil wars' a series of small engagements between China and Japan that grew into a conflagration that saw many countries sink to levels of barbarity that all of us had thought long forgotten. It started long before the shooting, when Japan used financial muscle and...

Duncan, you should join the Voluntary Human Extinction Movement! http://www.vhemt.org Cheers, Aceyducey PS: Asteroid might be a more serious threat. There is one passing by in 2029 that might get us on the next pass.

Wahahaha.... http://www.atimes.com/atimes/Asian_Economy/GE18Dk01.html It won't stop at $3.... And the other side: http://www.wired.com/news/planet/0,2782,67523,00.html?tw=newsletter_topstories_html Cheers, Aceyducey

Note that modern cars (all since the Model T) are NOT designed to run on ethanol and you are taking a risk by doing so. Check your warranties & what the car maker says before running any ethanol/petrol mix in your vehicle. BTW: 90% petrol and 10% ethanol won't make much of a dent in fossil...

Merovingian, I suggest you investigate the feasibility of widespread use of hydrogen cells. (here are good places to start http://www.idatech.com/technology/fuel_processors.html, http://mb-soft.com/public2/hydrogen.html) You'll find that we're certainly not there yet and due to the physical...
