i feel like our guess is a joke. we would like to see one thing but i know thats not what we are going to see in the ending. i feel like we are told so much bs now days i dont know what is true and false. any choice we make or want its going to cost us more and more taxes. yet the things they are supose to be paying with certian taxes they dont. so whatever the turn out im sure i'll have to live with or do without.
one other thing yeah we can use hydrogen but then there will be water there already is so then we will get charged more for water

GIVE ME A BREAK!!! Hydrogen IS renewable, it CAN be extracted from WATER from right inside a vehicle engine compartment, it CAN run a current automobile motor design, current motor designs CAN be easily modofied to run that way and it can run an ordinary housecar motor at upwards of 200mph. It gives off WATER as an exhaust gas. DONT listen to the car companies, they want to give you hydrogen vehicles that you refill at hydrogen stations...thus replacing gas stations. The technology has been around since the late 1800's, but at that time the cost of the parts needed to generate the process was astronimical. When plans with cheap parts(I have plans from the patent office)became available, the idea was bought, shelved and only became public property in the early 2000's.

In response to Zuul, hydrogen is one of the most abundant chemicals in the universe, we'll never "run out". Stars are powered by it. And as for electricity, have you seen your electric bill lately? Everyone gripes about the cost of electricity. Can you imagine how much it would cost to charge 2 cars per household, assuming you don't have teenagers with cars. I can't imagine that would be cost effective. I also can't imagine being on a long trip and pulling into an "electric station" and waiting an hour or longer for my car to charge up so I can keep driving. Not practical.

I do believe that we have the technology that would sever our dependance on foreign oil and I also believe that its the oil companies that keep it from us. If I remember correctly we had diesel cars in the seventies that ran 50 miles to the gallon. Why not now? No matter what they come up with, the only people that would be able to pay for the cars are the rich. Even if the new tech. cars were affordable, the repairing and replacing of parts would break the bank.

I read on a post sometimes back about a compressed air motor to power the drive train. If that could be coupled with hydraulics, I think we would have the power we need to move even larger vehicles.

It is very evident that we need a new technology to power all of our gas driven vehicles...and it should have been discovered long what gives? The Oil companies must be keeping that technology under keep us ALL dependent on them. I know that there must be someone out there that has already come up with this age old time is running out on our continuing to use oil as an energy source.

I don't remotely pretent to be a physicist, but it's still pretty clear to me that the problem with all of these is that they are single-use sources. Moving from one finite source to another does not solve anything, it simply buys us a bit more time before we have to deal with the actual problem. It's completely illogical and defines insanity.

Why aren't we trying to harness "reusable" energy? Vehicles spend a lot of time in motion. Simply by being in motion they are creating... yup, you guessed it... energy! With every rotation of the axels, there is the potential for turbine energy to be collected. With every physical movement, there is the potential for wind energy to be collected. (And while we're at it, why don't we use turbines along highways to capture the wind energy created by cars on the road and use it to power street lamps?) Mix in some solar and you've got a virtually self-propelled vehicle with a bit of a sun burst!

Now, I know that there are issues with the weight & size of the batteries and the systems needed to turn the raw energy into useable "fuel." But, whatever, scientists have solved more complex problems than these.

It just seems so simple to me. It makes me wonder if I'm missing some huge detail that would explain why we're still wasting our time, resources and brain-power investigating all these ridiculous non-renewable fuels.
I suppose that if we could get the greasy paws of big, greedy oil off the capital button, we would have a chance to take a more serious look at logical renewable resources.

i say biodiesel, installing a kit on your car to take wvo/svo, no one is going to give up their french fries or chicken wings anytime soon, so there will always be a supply of vegetable oil to reuse. i mean now we have yam fries!!! they are so good!!! anyways, im looking to buy a delica which runs on diesel, then build it up to use biodiesel and then install one of those kits to run it on wvo/svo? not sure which it is, but by the time i do it i will :D

Why is Hydrogen #1? Do you people just repeat the last buzz word you heard on TV? Damn monkey see, monkey doo (yes I spelt that right).

With electricity you could refuel AT HOME!!! It would be a universal power source. Then more development could be put into the singular objective of producing electricity more efficiently instead of diversifying efforts into creating yet another fuel type.

I voted for biodiesel.
We will eventually run out of crude to make both gasoline and real diesel. We can't grow enough corn to make enough ethanol. Maybe some other cost effective source of ethanol with replace corn, but until then that is not the answer. The infrastructure will take some serious time and money to make electricity and hydrogen a good solution. One can argue that we already have electricity, but there is not enough if we add the load of charging a nation of electric cars. Large generating plants are still coal or natural gas. We need to start building fission plants again and get back to doing serious fusion research. Battery technology is not there yet either. If I have the luck with a rechargable car that I have with rechargable toothbrushes, I'm screwed.

Biodiesel is renewable and in many cases we can recycle stuff that would otherwise be thrown away. Engine technology exists already. The distribution system is there. We would use the existing gasline system. We just have to make biodiesel in huge quantities. So I think we are closest to a biodiesel solution.

Put bigger tires on the back and smaller tires on the front. You're always going downhill so you just coast. No fuel necessary :-)

Wind up cars. Put a big coil spring underneath with a wind up key on the back deck. Make the kids (yours or a neighbor's) wind it up every night so you can get to work every morning.

CO2 - Develop a way to detonate the carbon in CO2 to run the engine. Exhaust should be just the O2, pure oxygen.

Rubber band (1 really big one) - Same technology used in toy airplanes. Twist the propeller until the band is really tight then release the brakes. Always park facing the wind or a politician.

I would like to see a variety since not one technology will resolve all the other issues. For the immediate I would like to see us use technology already in existance and available such as bio-diesel. Europe already has found that diesel autos are very efficient so lets get them into the USA.

Since the assumption is "equal availability and cost effectiveness" the natural choice would be gasoline since we already have that technology and are well vested in it. Retooling to a new technology could break the bank.

However, it would be nice to see a technology permeate through that goes a long way towards eradicating our greenhouse emissions.

grilln_mama - for purposes of this survey, it doesn't matter how it is produced. The question is about how energy is stored in an automobile to power it. Everyone seems to like hydrogen because it burns clean, but they don't understand that it needs to be pressurized or liquified and kept that way, which throws away much of the energy, adds weight, and reduces the range to worse than current batteries. Hydrogen with a carbon carrier works just great, however.

Secondly can someone clarify for me what the hydrogen is? I know it is a gas, but how is it produced?

No matter what technologies we come up there will be some environmental group that will complain about it. First it was the pollution that the cars and trucks gave off. We solved that. (And no carbon dioxide is not a pollutant).

Then it was fuel economy. We kinda tapped that out at 25 to 30 mpg for a "comfortable car". 35+ mpg for a cramped compact. 40+ mpg for exotic cars (hybrid, battery) that have a higher environmental impact from their production and disposal.

When are people going to learn that there are some that just wont be happy until all cars are off the roads and we live in mud huts again.

The thing people are missing is that hydrogen isn't a fuel, it's a battery. It's a storage medium for electricity.

Even though hydrogen is the most common element in the universe, we don't have large quantities of pure hydrogen on Earth. We can get hydrogen fairly easily by passing electricity through water. That electricity has to come from somewhere, though. Ideally it would be a renewable source.

So once we've used up some kilowatt-hours and gotten hydrogen in return we can consume the hydrogen in a fuel cell or through some other means and get energy back from it, often in the form of electricity. They hydrogen serves the same function as a battery, but it's lighter and fairly easy to store and transport, if you do it right.

But hydrogen is NOT an energy source on Earth because we don't have plain old hydrogen lying around in any quantities.

I think the immediate solution is battery and gas engine. It will be the quickest to manufacture and cheapest in the long run. I like hydogen
but it will take years yet to develope. The dual battery and gas gets excellent mileage.

In the near future that is electricity. We are currently dependent on it, and that is not going away, it can be created quite easily, and its in many homes in the world. Heck, it is far closer to more people than are gas stations. The issue will be battery power. If sufficient battery storage is not available to allow an electric car to be more or less equal to today's gas powered models, then it will probably fail.

In the future, hydrogen may become the fuel of the future if electricity goes by the wayside due to lack of sufficient storage, then I suspect hydrogen will take its place. But new engines will need to be created, along with filling stations that do not exist now. Sure, the fuel is easy to get, but distilling it, and transporting it are going to make it like oil, which the big companies want.

How many of you all went to the Shoreling Solar Fair a couple of weeks ago and saw the electric cars that were home built? It was amazing. I would like to make one.

If it's efficient you can bet your bottom dollar the feds will try and squash it. They are already hurting in the revenue department due to high gas prices = less fuel consumed = less tax revenue raised = a crisis in the highway road maintenance fund........
