What is the best alternative fuel?

Question

I am doing a project for Penn State, and I am a student at a local middle school, I need to design a brand new alternative fuel powered vehicle.

Answer 1

Hydrogen is definitly the fuel for future bt no u cant use it at local level.......hmmm i remember once with a few citrus fruits i powered a scientific calculator.Maybe u can use dat.

Answer 2

WVO.

Answer 3

Compressed air is the cleanest and best one so far.  It's cheaper and might make gasoline obsolete soon.

"BBC News is reporting that a French company has developed a pollution-free car which runs on compressed air. India's Tata Motors has the car under production and it may be on sale in Europe and India by the end of the year.

The air car, also known as the Mini-CAT or City Cat, can be refueled in minutes from an air compressor at specially equipped gas stations and can go 200 km on a 1.5 euro fill-up -- roughly 125 miles for $3. The top speed will be almost 70 mph and the cost of the vehicle as low as $7000".

Hydrogen is a great option for the concept of free energy.     I built my first hydrogen cell about 5 years ago and now currently run 2 trucks, my home hot water heater, home stove and home generator on hydrogen for free with caught rain water and the help of a $10 solar panel.  I offer a step by step DIY guide to walk anyone interested threw the process. You can find it at www agua-luna com or you can email me.

There are basically 3 safe ways to make and use it... chemically, electrically and molecularly, the first 2 being easier so I'll only discuss them here. The fallowing steps were taking directly out of a DIY guide I offer to those who would like to run their vehicles or home on hydrogen safely. The entire guide is available at www agua-luna com

    On demand h2 generators are a bit different from the Hollywood versions like seen Chain Reaction with Keanu Reeves, that tend to explode violently every time a film is being made. However when used in an on-demand system there is no storage of hydrogen and oxygen in its gas form, only liquid (water) and is only transformed into gas “on-demand” in small cylinder size amounts. It’s actually safer then gasoline as it doesn’t evaporate, creating explosive fumes in the tank like gas.

    Chemically

    1. You’ll need a 6inch x 1ft schedule 40 pvc pipe. With pvc cement glue a cap on the bottom and use a s***w on cap for the top. Drill a small hole (1/4inch or so) in the side close to the top, s******g in a small copper shut off valve. Place a few feet of stranded (food grade is good) flex hose to the valve and into the air intake of your engine (carburetor or fuel injections).

    2. Now crunch up a couple aluminum cans (beer cans, soda cans etc) and drop them into the pvc pipe, along with a couple cups of lye (Red Devil drain opener has lye in it, some Clorox and Drano’s do to).

    3. Then simply add water, s***w on the top and wait a few minutes.

    What happens in simplicity is that aluminum and lye don’t really get along so they battle, and as always the innocent civilians (water H2O) that the most casualties, by giving up its hydrogen and oxygen. This then builds up in the void of the pipe and is ready to be vented into your engine, by opening the valve. You may need to start your engine on gas then switch it off after the hydrogen starts burning.

    Electrical is a bit easier then Chemically.

    1. Simply take a small solar panel 1.5 amps is what I use ($9 at harborfreight.com), connect the 2 wires from the panel +- to 2 conductors (carbon cores of batteries work well, just be careful removing it from the jacket), but any conductive material will work ie. Copper, aluminum, steel, etc.

    2. Drop the wires into a water tank (I use 55gal drums), make sure they don’t touch each other.

    3. Drill a small hole (1/4inch or so) in the side close to the top, s******g in a small copper shut off valve. Place a few feet of stranded (food grade is good) flex hose to the valve and into the air intake of your engine (carburetor or fuel injections).

    4. Then simply add water, s***w on the top cap and wait.

    After a few hours tiny bubbles will form and rise off one conductor (that’s hydrogen) and even smaller bubbles that just looks like foam will rise off the other (oxygen). I don’t remember which likes the positive and which likes the neg hydrogen or the oxygen.

    The third method is more complicated and is what I use for my vehicles. It’s just a modified Joe’s Cell, there’s a step by step DIY guide available to walk you threw the process here www agua-luna com

It also covers the other 2 methods described in more detail.

Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at  www agua-luna com on the subject. I also offer online and on-site workshops, seminars and internships to help others help the environment.

Answer 5

Electricity.

Even with the current US power grid mix (52% coal), EVs produce lower greenhouse gas emissions than gas cars, hybrids, and even plug-in hybrids.  I can provide a metastudy demonstrating this if you'd like.

Electric engines also don't have moving parts (unlike internal combustion engines), so they last much longer.

Hydrogen is not practical because there is currently no environmentally friendly method to extract the hydrogen fuel.

Biofuels have serious problems as well:

'Air cars' are basically just another form of electric cars, because they store the energy used to power the air compressor in the compressed air, then use that energy to mechanically move a piston.  However, this process is far less efficient than an electric motor (90% efficient), so basically an 'air car' is just a less efficient electric car, so I really don't see the point in them.  It's like taking a step backwards.

Answer 6

Honestly, the most efficient fuels are those already in use.

Electric vehicles are wonderfully efficient at stopping and starting, but are horrible at prolonged constant speed. Electricity is usually made by the burning of fossil fuels in this country, and electric production would have to be greatly expanded if were were to convert to electric vehicles or super hybrids.

Ethanol (E85) is horribly inefficient and actually destroys an engine running on it. It gets about 1/2 the fuel economy as gasoline when used in the same vehicle which nullifies any benefits it might have had. It also takes oil to make ethanol, with the most efficient productions only getting a 6% profit margin.

Biodiesel is the only one of the alternative fuels that is actually better for the vehicle. It gets better fuel economy, lower emissions and also manages to lubricate a diesel almost as well as the old high sulfur diesel fuels. However, a diesel engine cannot be started on pure biodiesel, it is nearly impossible to use in cold weather and it gels far easier than standard ultra low sulfur diesel.

Hydrogen is a wonderful idea, but nothing more. It takes far too much effort to manufacture in great amounts and it also requires oil to produce. It is also very hard on engine components~ water destroys most metals!

Gasoline electric hybrids are the worst in a long line of bad ideas. They're not much better on fuel than your average small economy car. For the price and problems they experience, its not worth while.

Now, the true future of economical engines is diesel. Diesel is far more powerful than gasoline, diesel engines also get much better fuel economy. They're long lasting engines, you get sick of looking at the vehicle long before it shows any signs of wear. They're also fairly cheap to build. They've become much cleaner~ the days of belching black smoke are long gone. In the next few years, you'll be seeing far more diesel vehicles in the American market from makes like BMW, Mercedes~Benz, Honda, Toyota, and Ford plans on launching their small european diesels into the American market.

Perhaps we'll see vehicles like the 1980's VW Rabbits, whose engines would turn off when you were sitting at a red light, then start back up as soon as you hit the gas to go. Simple ideas like that are going to lead to the future, not the overly complex and expensive folleys.

Answer 7

A car company in China made a car with an electric engine for each tire, and it ran with 500hp.  I think we can really improve electricity now, nuclear soon.

Answer 8

Nuclear is  the best we have today that is proven to have the capability to provide the massive amount of RELIABLE 24/7 power we need. Solar / Wind / etc. can help, but are not always reliable and are more expensive as well.

Alternates for cars is probably Bio diesel. Diesels have proven to be cheaper, simpler, and gets better mileage than hybrids. Maybe a hybrid diesel? Car fuel is not as important as our energy for electrical power anyway. Cars produce less than 10% of the CO2 man makes. I understand man only makes about 10% of what nature produces. Seems like cutting car emissions in half will do only a little. Building Nuclear Plants will have a much larger impact.

Answer 9

Fossil fuels are the best as the earth has been recycling them for millions of years. It if fissile plants that produce most of our Oil, Gas, and after a long time coal.

Answer 10

Methanol. Because it is easier to make than ethanol or hydrogen or any other alternative fuel.
