which fuel alternative you think is better? why?

Hydrogen. You can create it from water using only electricity so it's the cheapest fuel ever. When you explode it (during combustion), it mixes with oxygen to create...you guessed it...water (no polution).\n\nSo:\n1.Free\n2.No polutants\n\nHmmm...

There are many alternative fuel vehicles.  Some are on the market today, others are simply concepts.  I'll give a quick rundown of the more popular ones:\n\n1. Flex-fuel vehicles - More than 20% of cars on the road today are flex-fuel capable, which means that they are capable of burning a fuel known as E85.  E85 is 85% ethanol (which is an alcohol made from corn) and denatured with 15% gasoline.\n\n2. Compressed Natural Gas (CNG) vehicles.   There are fleet and government vehicles that will run on compressed natural gas.  The engine technology is similar to that of a gasoline engine, with the exception that it has been configured to use natural gas instead of gasoline.  Due to the lack of a refueling infrastructure, privately-owned natural gas vehicles are not very common.\n\n3. Liquefied Propane Gas (LPG).  This is also a fuel used by fleet vehicles, in particularly trucks.  One of the larger users of these vehicles is the Schwan's Foods company, with their big yellow refrigerated delivery trucks.  These trucks use LPG as their fuel.  \n\n4. Biodiesel.  This is a type of diesel fuel that is made from plant or animal fats and oils.  It can be used in most diesel engines with little or no modifications.  Blends such as B5 (5% biodiesel, 95% petro diesel) and B20 are available, as well as the full 100% biodiesel.  Watch for growth in this alternative fuel.\n\n5. Hydrogen.  This fuel can be used both in a standard internal combustion engine like those in cars now, or to generate electricity by feeding it to a fuel cell to generate the electricity, which then runs electric motors.  The problem right now is storing enough hydrogen onboard to make this a feasible concept, as well as developing a safe way to store it.   Most hydrogen-powered vehicles are only concept cars being tested by automakers.\n\n6. Electrical.  Electric cars have been in experimentation for many years.  The problem is storing a sufficient amount of electrical power on board to make them feasible.  If significant advances in battery technology were made, this is a possible concept.\n\nAll of these are still in some degree of experimentation.  However, E85 and biodiesel are real products are on the market for consumers to use today.  As oil prices escalate, these alternative fuels will develop more market appeal.

of course gas but if cant get that any flex fuel additive sold at auto stores. (or can order by gallon for you) with common ratio of 1 pint additive to 5-10 gals coco or other subsitute. theyll know which is best. also if use gas youd want 1 gal per10 gals of your substitute fuel.

alcohol burns faster, hotter, which gives you quicker throttle response, these motors are quiet more expensive than fuel motors

Essentially, used engine oil is better and easier to refine (IE cleaner) then crude. More on it. http://www.epa.gov/epaoswer/hazwaste/usedoil/usedoil.htm

We can replace a lot of fossil fuels with methane energy. There's a town in the US which is almost totally run on methane gas from an intensive feedlot. If there was a will to do it there would be methane digesters and collectors on all sewerage systems and intensive farming installations.

Well I never had an old one, but I certainly love my new one.  I have a hemi durango and it's hot as hell.  Costs a lot for fuel, about 60.00 per fill, but it's worth the driving experience.

Not Totally. I Hear Everyone Complaining about the High Cost of Gas. I've Found a Way to Convert Regular Pump Gasoline into Propane.My Unit is Safe, Compact, and Uses Low Pressure Air to Do It. But, it's Illegal to Put on Any U.S. Vehicle Made From 1996 to the Present, even if Fuel Economy is Improved, and Emissions are Lowered.That's the EPA-OBD-II Vehicle Inspection Law.We Can Thank The Clinton Administration for That.If a Vehicle Does Not Emit Enough Pollution, It Will Fail Inspection, and be Illegal to Drive! This is Insane! I've Been to the US Patent Office and Looked at Patents Kept Off The Market. Case in Point, the Pogue Carburetor, Which is On File as Having Achieved 100 + MPG With a Flathead Ford V-8 That Normally Got 15 MPG!All OBD-II '96 ^ Engines are Set To Run 14.7 Parts of Air to 1 Part of Fuel.My Vaporizer Does 100 Parts of Air to 1 Part of Fuel, With an Actual Increase of Engine Power, and Longer Life. 50 + MPG With even the Largest SUV! And, It's Illegal! If I'm Wrong, then How is it That Engines DO Run On Propane? To Do So Legally Requires the Use of a Large, Cumbersome, Expensive Tank Cylinder, Which must be hauled with the Vehicle, Expensive Metering Equipment, and the Added Hassle of Having to Refill the Tank.So Much Hassle that even with Gas Going Back to $3.OO Per Gallon, it's Just Not Worth the Hassle!Again, I've Heard it Over and Over Today, and Tonight, People Complaining About the High Cost of Gas. Know What? All Petroleum is Essentially the Same on a Molecular Level. Only the Dispersal is Altered. But The OBD-II Law, that Applies to the Vehicle That You are Driving Can't be Altered! Most People I Try to Explain This To Don't Want to Hear It, But They Still Complain About the High Cost Of Gas. I'd Like to Fix Up Older Vehicles Converted to Vapor, and Donate Them to The Meals On Wheels Program, Volunteer Veterans' Services [We Owe Them So Very Much!] Homeless Shelter Assistance Centers, and Many Other Worthwhile Charities! See, Greed has Stopped This Every Time! Now, The OBD-II Law. So, No, I'm Not "Happy Tonight"!

vote... all this middle eastern saber rattling is driving the prices sky high...\n\nhe obviously doesn't have money to invest in "alternative fuel" vehicles... what are you people smoking?

Try creating alternative fuel. I'm reduced to cycling since the recent fuel price increase.

No. It just wastes more gas, builds up carbon deposits in the cylinders quicker, and tends to make the engine an oil burner.  There are many possible reasons why his is faster, but worse than optimum combustion isn't one of them.

The most important thing right now is that it can be used as fuel. It is much cheaper than gas and also does not cause pollution. We have used it as rocket fuel for years but only recently have we developed vehicles that can run on it. They are in California.

It can be reduced with better air emission controls. That is the center of what is going on today. That is why we are looking for better fuels to burn...better cars, decrease smoking, DEPA increasing controls and stricter guidelines. There are many things, being done today to reduce pollution. The lifestyle we have will not allow pollution to be 100% prevented.

the pros are that it is a renewable resource, the downside is that the mileage is lower than using gas. i have no idea why it isn't in larger use now, even though the mpg is lower, it would result in energy independence if there was widespread use of ethanol.

Nuclear, beyond any shadow of a doubt. \n\nThe US has appreciable Uranium reserves itself, and major Uranium producing nations such as Australia are already favored trading partners and stable western democracies.\n\nForget corn. It takes more oil to produce ethanol than the ethanol replaces. I. other words using corn for energy means we have to use MORE oil. We currently produce corn ethanol as an economic subsidy for corn growers. If we didn't make ethanol we would have to dump that corn in the ocean. But Corn ethanol is NOT a fuel source. See the first article below.\n\nHydrogen is iffy. We can only obtain hydrogen by splitting water using massive amounts of electricity. That electricity has to be obtained using normal power stations, usually coal. As a result hydrogen is like ethanol: it takes far more fossil fuel to produce than it actually replaces. That makes it a possible oil substitute but very unwise WRT greenhouse gas emissions unless coupled with lots of nuclear power stations.\n\nSolar and wind are never going to be major players. There simply isn't enough land available to make more than a minor contribution and because the supplies are erratic we would still need other power stations to make up the regular shortfalls. See the second article below.\n\nNucelar is the only real solution.
