WOW, Toyota Hybrids upcoming
 
Just checked out the specs on the 2007 hybrid Camry coming soon.... 43 city 37 hwy... wowza for a full size car. Then I tempted myself and droooled over the Lexus GS450H... couldn't find mileage specs but I would guess 35ish city 30hwy seeings its a powerful combo. Tho I could have 2 RX8's for the price of the GS450H... lol

therm8 02-05-2006 07:57 AM

43/37? I highly doubt it. Particularly the 37. Hybrids don't do well on the highway. I'd think a full size car would fall prey to this moreso than the little ones. My guess is 25-30 hwy.

terrypk1 02-05-2006 08:30 AM

i don't trust their stupid fuel milege thing at all. according to many magazines, in the end of their tests, they all find the hybirds to be inmature technology. Even though many of them do save fuel(just not as good as stated by the manifactures), it will take 3 to 4 years before you can get the money back, since the cars are just more expensive than normal engine cars.

zaglo6204 02-05-2006 10:13 AM

people who actually dish out the dough for a hybrid are either stupid thinking that they will save money, or they are actually buying them for the sake of the environment, knowing they will not save money. or they just want to be 'unique'.

raspyrx7 02-05-2006 03:57 PM

well I'm not sure that 43/37 is all that off... my bud gets 30/38 with his current camry

UFGator12 02-05-2006 10:12 PM

Yeah, I saw the commercial for the 2007 Camry. Looks pretty good too if I might say so.

Roaddemon 02-06-2006 09:28 AM

The hybrid accord boasted high mpg too, but in street test driving only got 25 mpg average. Hybids are only a temporary fix untill hydrogen cars are fully developed. The 4 cylinder accord still gets 38mpg. If I want economy I'll buy that.

Hydrogen powered fuel cell cars won't displace hybrids.


Bill Reinert, U.S. manager of Toyota's advanced technologies group, was asked in January 2005 when fuel cell cars would replace gasoline-powered cars or hybrids, and he replied, "If I told you never, would you be upset?"
Assuming a hydrogen fuel cell car would cost $50,000 instead of $1 Million (what they do cost now).
Assuming a hydrogen delivery infrastructure for $500 billion was actually safe and already in place.

There's still one huge problem left:
So far a technology to produce hydrogen environmentally friendly in a large scale has not even been invented. (Keep in mind the internal combustion engine was invented 150 years ago).
Hydrogen is currently produced from carbon based fossil fuels, this procedure produces almost the same amount of greenhouse gases as a hybrid. Why take the complicated detour and not burn carbon based fossil fuels directly as we do now anyway.


And any future excess zero-carbon electricity would be better used to charge the battery on a hybrid that can be plugged into the electric grid. Such a "plug in" hybrid or e-hybrid can travel three to four times as far on a kilowatt-hour of renewables as a fuel cell car, since it avoids the huge inefficiency of converting electricity to hydrogen and then back to electricity.

raspyrx7 02-06-2006 08:34 PM

just listened to a podcast bit on a Civic sedan hybrid test drive... some flogging, some hwy, some city (w/traffic) that resulted 47mpg.... and if the price tag stays around $20g, I think I know what my wife's next car will be.... and it'll offset my desires for an RX8 and its mpg.

brillo 02-06-2006 08:37 PM

each generation of hybrids have gotten better in terms of actual mileage, forgetting the EPA for a second.

Honda's hybrid system can't drive the car on battery alone like toyota, hence, the accords lower mileage.

This version seems to be more economy than performance, so I would bet in city (which to me is the most important) it gets in the very high 30's, which for a sedan of that size, its pretty freaken amazing

raspyrx7 02-07-2006 07:06 AM

what they need is a Hybrid with a motor for each wheel.

I think you will be proven 100% correct.

I think what we will probably see is hybrids at first, then plug-in hybrids soon after. Once there are enough plug-in hybrids, gas station owners will start offering plug-in stations. Consumers will be looking for them once they realize that plugging in is substantially cheaper on a per mile basis. And this would actually be practical what with the newest 5-minute charging lithium batteries. Plus, there is already a massive manufacturing/distribution network for electricity--not so for hydrogen. Then eventually, battery tech keeps advancing (europositron?) to the point that the gasoline engine is rarely used, and viewed as an increasingly unnecessary extra expense (and maintenance headache) for most people. Carmakers will offer engine delete options, replacing the space with more batteries and offering nearly the same range. Eventually, carmakers stop selling gas models alltogether, and future generations look back on all today's hydrogen fuel-cell blabbering in the same amused way that we look at early attempts at steam-powered cars of 100 years ago.

Roaddemon 02-07-2006 02:25 PM

No to that, Hydrogen will be the future and there is extensive research, backed by our goverment, right now, to assure it. Hydrogen fuel cells will take the place of combustion engines. Just a matter of time. Hydrogen cars are being developed my Mazda and other manufacturers. I suppose alot of people never thought the the automobile would replace the horse in 1903. It will happen in my life time.

On another note. My loaded $20g 2000 Mazda 626 gets average 22 mpg. and is a very nice car. I drive 6000 miles per year. A hybrid averaging 45mpg would save me a wopping(sarcasim) $350 per year at $2.50/gal and give me car payments again. My car will last me another 8 years and it's paid for 2 years ago. So economically a hybrid means nothing to me but added expenses. I do think it would be nice to have a car that gets 650 miles/tank. Especially when fleeing a huricane or when there's a gas shortage. If I lived near New Orleans I'd go buy one today.

BaronVonBigmeat 02-07-2006 03:02 PM

The fact that the government has spent money researching it means nothing, they did the same in the 70's and nothing came of it. If anything, it's a sign that a certain technology is an unworkable boondoggle which needs government support to prop it up.

Not that hybrids are really all that much better. They really don't make financial sense unless gas remains fairly expensive, and you keep the car for a good while. But if enough people buy them, the price difference is bound to drop...as opposed to a fuel cell car, in which you've got to pay for the new car tech AND the new hydrogen generation and distribution network. Really, the only reason for the fuss about hydrogen is because the battery-powered cars California tried to push off on people were so totally impractical. Hydrogen cars can be quickly refueled, so all the hype switched to hydrogen cars. But in the meantime, battery tech has quietly improved to the point where you can have 120-mile range and 5-minute recharges (!). If that's possible...why bother with hydrogen?

http://www.greencarcongress.com/2005...eavy_suba.html

Also, comparing a 5 year old car to a new hybrid is kinda silly. They make more sense when you're comparing a new hybrid to a new conventional car (or a new hydrogen car and it's related expenses). Also you forgot about plug-in hybrids just over the horizon, which for someone who doesn't drive very far could mean much bigger savings than just $350 a year. Depending on your local electricity costs, of course.

bascho 02-07-2006 03:10 PM

I think the first escape from fossil fuels is Ethanol. I just read an article about Brazil and how 83% of the vehicles sold there are flex fuel capable. They are the largest producer of Ethanol from Suger Cane crop and save something like $62 Billion USD a year on fuel. That is $62 Billion USD staying in their country, going to their citizens and creating jobs on farms on their land. All of the 35,000 gas stations in Brazil have Ethanol tanks and pump either Ethanol only, plain gas, and various mixtures of both such as E85. Currently this is not an option for most of the world as Suger Cane is not an easily adopted crop. Corn is easily adopted to many climates.....but it's a lousy source of Ethanol. There are several companies working under government grants to develop enymes capable of breaking down compost into Ethanol Cellulose (which is the best source of Ethanol).....but this is a few years away from being implemented in mass production on Ethanol.

Minnesota is the only state that is really pushing Ethanol here in the US. E85 is available at most of the gas stations throughout the state and flex-fuel vehicles have seen as sales spike because of it. More states need to get on board with this transformation to optional fuels to help build an infrastructure that is decades away from being stable.

Hydrogen will be the next alternative to fossil fuels...but I think we are a decade away from making that viable. I did see a special on National Geographic about a research team working under a government grant has identified a micro organism in sea water that is capable of releasing Hydrogen from the H2O through photo synthesis. He predicts that gas stations will be able to pump Hydrogen from tanks that sitting in the sun behind the station just bubbling away producing Hydrogen biologically emitting only oxygen into the air.

Roaddemon 02-07-2006 03:24 PM

I read somewhere our space progam is using fuel cells in our spacecraft. The usa wants to spend 100 billion to send people to Mars In 10 years. Fuel cells would play a roll in such a distant trip. Things will open up for hydrogen fuel. It wil take alot of little inventions and planning, not one big break through.

Natural gas is also being experimented for fuel cells and alternate energy in China. They have huge natural gas reserves and want to capitalize since they consume huge quantities of the worlds oil.

As you mention ethanol is another resource but I thought is was expensive to produce.

Roaddemon 02-07-2006 03:43 PM

Yes the plug-ins might be nice. They would probably be bubbly little bug cars with no luxury or room for comfort. And then you have to worry about traveling any distance. You just know it's going to happen. 10miles from home and a dead car. Lets say there's a power outage and your plug-in does'nt get the full charge. How would I get to work the next day. I think they would be novelty cars for a few. Would they still be operational if they loose charge? Could be nerve racking owning one. I don't know much about them.

bascho 02-07-2006 03:44 PM

It is and it isn't. Currently it costs $.17 per gallon to refine ethanol. The high cost is the % of corn crop that would be needed to support an ethanol only fuel source. I read that if all the worlds corn crop were used to extract ethanol, we would barely cover only the US demand for automotive use. To be able to meet the needs of the world, the only viable source of ethanol is from ethanol cellulose. Ethanol cellulose is the most abundant source for ethanol in the world because it can be extracted from tree bark, grass, woodchips, and other plant material. Unfortunately, it's also the hardest source to refine......but that will change in the very near future.

For countries like Brazil, suger cane and soybeans are very inexpensive to grow and refine.....in fact, sugar cane can go from crop to fuel in one complex. The farm on one side and the refinery on the other. It takes very little energy to extract the ethanol and the process is clean.

Here is a link to a great article on MSNBC about Brazil's world leading ethanol economy. http://www.msnbc.msn.com/id/8262015/

Roaddemon 02-07-2006 05:22 PM

Thanks, I read it. Ethanol looks like a good alternative in this country. it's a matter of greedy American oil companies stepping aside and goverment intervention to let it happen. We can't afford another disaster in the gulf. I watched gas prices go fron $2.25 to $3.50 overnight in Milwaukee, Wi. on the eve of Katrina. Stop the gouging Exxon. We really need an alternative. Hybrids won't stop exxon from gouging us again. Even 43mpg means nothing when gas prices reach $3.50 or $5.oo/gal. Who can afford it? The real solution is alternate fuel.

How is it gas can go up 25cents over night and then take 3 weeks to drop back down to where it was? We're being gouged even now. Too much politics at our expense. Hybrids will just make us move further away from our jobs and buy even more gas. Adding fuel to the fire so to speak. We have to break our dependancy on oil period. That's my view.

Japan8 02-07-2006 09:10 PM

The Hybrid and electric people seem to be forgetting a couple important things...

Um... Batteries have a limited number of charge/discharge cycles that they can do. Li batteries in particular have problems with "memory"... that if they are recharged before being fully discharged, over time they will lose that difference in capacity. Don't forget that all batteries are toxic waste. Where do you plan to dispose of them? The more people use them, the more waste and they'll likely need to change batteries at some point in time as well. Even more waste!

Charging stations? And just where will they be getting power from? The power grid... fossil fuel powered power plants. If fuel costs are high, so will be power. Yep, we really solved the problem there.

All you've done is created more toxic waste (batteries) and just transferred the the fossil fuel issue (pollution and cost) to power plants (which pollute worse than current brand new cars anyway). Opps... we also forgot about diesel trucks and airplanes...

Hydrogen WILL become the fuel... one day. Be it internal combustion or fuel cell. It won't be tomorrow, but I bet you'll be seeing it within the next 100 years. As they say... necessity is the mother of invention. It isn't so necessary yet... so it hasn't come about, but that day is coming. Hydrogen is the most plentiful element in the universe. Why the hell WOULDN'T you use it?

BaronVonBigmeat 02-08-2006 08:26 AM

I was under the impression that the newest Lithium batteries are fairly nontoxic and didn't have memory problems. Hmmm.

Yes, a lot of the power would come from fossil fuel electricity plants (the same is true for hydrogen generation). That's why we need to get over our irrational fear of nuclear power. But even with a conventional power plant, it still works out to be significantly cheaper per mile than burning gasoline, if you're looking at fuel costs. And pollution is much easier to control at a central location than at thousands of individual cars. Modern power plants are cleaner than cars.

The reason you wouldn't use hydrogen is because you can't drill a hole in the ground and pump out liquid H2 of course. It's just an energy storage medium, like a battery. If hydrogen generation/distribution/fuel cell tech advances enough, it will be the fuel of the future. If batteries prove better, they will win instead. My money's on the batteries, but we'll see.


High Power. A123Systems’ first product packs up to five times the power density of current rechargeable, high power batteries. In addition, the battery has the ability to recharge to 90% of its capacity in five minutes.

Intrinsic Safety. Unlike conventional Lithium-ion batteries, A123Systems' batteries employ new thermally stable, non-combustible active materials, enabling a safer cell and allowing cost reductions such as the elimination of unnecessary battery pack components. In addition, A123Systems uses an environmentally friendly chemistry.

Long Life. With up to 10X improvement in life over existing rechargeable batteries, A123Systems’ batteries can deliver thousands of cycles at high rates. Cycles refer to the number of times a battery can be charged and discharged before it no longer has any power remaining.

Because of the hurricane. Refining capacity was tight before, so it took a while to catch up with where they were.

Remember too that Brazil is somewhat unique in that they can grow sugar cane for their ethanol. Even then, ethanol production had to be subsidized. Seriously, any time you see a story on ethanol, hit CTRL + F and then type in the word "subsidy". You'll never ever be disappointed.

Spikes in gas prices are directly related to the absense of a competitive alternative. Some people think that individual gas companys are the competition to each other......but that is bull shit. If Ethanol became a REAL alternative, in that you could purchase E85 or pure Ethanol at a refueling station in every town, then the prices for gas would be stable. The oil companies are not raising prices to cover increased costs......its all a big game. Make the public 'think' costs have risen and they will pay the increased price. Of course when the oil company reports a QUARTERLY PROFIT of over a hundred billion USD, well, that just proves the costs of drilling and refining are still very low in relation to price at the pump. Guess what you get for that Hundred Bil.....a lot of politicians in your pocket making sure that a change to alternative fuel is a lengthy one.

What's wrong with a government subsidizing fuel production. The goal for any country should be reducing it's dependence on the Middle East. Our own government subsidizes many ventures......unfortunately most are not progressive to the well being of the citizens of this country.....except for military use. I think the only way the US could ever change infrastructure to alternative fuels would be through the government. The oil companies are never going to assist in this change.....they make hundreds of billions of dollars every year off fossil fuel dependence. In fact, they probably spend billions every year lobbying any proposals for government money spent in research of alternate fuel sources.

Do you really think that if the US government put half the money spent in Iraq into alternate fuel research that we wouldn't have a viable alternate fuel source tomorrow. Right now the total money spent in research is in the millions.....and probably not even the hundred millions. We've spent something like $500 billion in Iraq......imagine what $250 billion in research grants would have discovered.

I agree totally, Right now we are so fragile. Oil companies are a monopoly and playing it to thier advantage. Recently there was a price spike in gas. The newspapers reported oil companies used the excuse of unrest in Iran and Iraq. It's almost like the stock market. Any little disturbance or fear immidiately brings gouging to the pumps(overnight).

What would happen if a terrorist got in a little boat and fired a hand held Sam missle hitting one major oil platform. Gas prices would skyrocket.

If we all got 45mpg with hybrids, Exxon would produce less oil to keep the prices high. They could get by with less, control supply and demand and make even larger profits then present. Competition through alternative fuels is the only way to secure our economic future. Oil giants will economically neutalize any technology gains(Hybrids) based on fossil fuel. More nulcear power plants, electric and hydrogen cars, and Ethanol, are a must for our future economic health. They would also clean up our enviroment. We have to somehow competetivley sidestep oil companies for our future fuel needs. Right now we are at thier mercy.

BaronVonBigmeat 02-08-2006 09:29 AM

What's wrong with subsidizing alternative fuels:

* First, my main point is just that ethanol is never as cheap as it seems; most people are looking for alternatives because the price of gas is high. But if an alternative is even higher, what's the point.

* It discourages private research;

* It discourages conservation and rewards people who live further from work;

The oil companies may never push non-fossil fuels, that may very well be true. But if ethanol was an efficient use of resources, other companies would sell it, not to mention all the agribusiness corps. who would love to sell it. But it's not efficient, and thus not profitable compared to oil, so you don't see Archer-Daniels Midland setting up ethanol stations and undercutting Exxon's price per gallon.

I'm not a fan of the Iraq war, but if the gov't sunk $250 billion into research...no, I don't think it would result in any significant breakthroughs that would be applicable on a mass scale. Never underestimate the ability of government agencies to squander money.

A) "Gouging" is a good thing, it prevents shortages. I hate high prices, but I would hate standing in line for hours even more.

B) What would happen if a terrorist got in a little boat and fired a hand held SAM missle, hitting one major hydrogen plant. Or ethanol plant. Or coal power plant. H2/ethanol/coal prices would skyrocket!

C) Exxon would produce less oil only if they wanted to commit economic suicide. Their competitors would be happy to sell it. If you really believe this, can you explain why gas prices have been on a slow steady decline for so many decades? It wasn't that long ago (~10 years maybe) that we had gasoline under $1 a gallon where I live. Were oil companies being generous back then?

If the demand were high, South America would increase thier ethanol output and import to the US. Ethanol could be sold as a third fuel for cars that are modified just like desiel. The govern could subsidize price differences for ethanol car owners with tax breaks just like hybrids. It would help offset oil sales. Oil and politics will make sure to slow this kind of fuel reform.

The govermentt is already putting that kind of money into research. It's called our space program. Our Government has the solutions. They just won't apply until it's absolutly necessary. It's a big special interest game. Politics have to change before we can.

China is upsetting world demand for oil. We are gonna run out eventually. Supply and demand is causing some increase. Gouging is causing the rest. gouging is nothing but false impression, by oil companies, of supply and demand. Oil companies are screwing us.

Hybrids will be used in various shapes and sizes just because it makes sense. Everything from electric turbos to electric assist motors will really start to been seen in the mainstream within the next 5-10 years IMO.

To echo what others have said about Ethanol is that it requires huge subsidies. Whatever you think about "big oil" and the government, capitalism in general doesn't flow really well with large-scale, long-term subsidies -- not if money is the most important factor, which sadly it tends to be. Oddly enough, to convert a normal engine to use E85 is a very simple and cost-effective venture. Yet, the infrastructure changes that have to happen for E85 to work are extensive. I don't mean to say that and not back any of it up, but this is almost common knowledge at this point.

Hydrogen can be burned as a fuel (as with the RX-8 hydrogen hybrid), but it is largely considered wasteful because it is so un-dense (is there even a word for that?). The general hope is that it will be used in fuel cells in a liquid form tempered by some metalloid. In this form, hydrogen is incredibly safe. It's basically a big battery.

The reason why this is so important is two-fold. First, it can be easily dropped into an electric assist car with no problem and just more effectively take over the role of the old-school battery it replaces. Second, is that the car industry, oil industry, or government don't have to help subsidize this technology because other companies already are. Lithium batteries, the element with the highest electrical potential there is, is the limit to what conventional batteries can do. There are many companies trying to make hydrogen fuel cells happen so that they can use them as enormously powerful batteries for laptops and other mobile devices. Once all the development costs have been fronted by these companies, it's just a matter of simple economics before they're used for cars, houses, etc.

As for getting hydrogen, the general technique is by electrolysis of water. The standard argument is that it is incredibly wasteful energy-wise to extract hydrogen this way. However, renewable energy like nuclear, wind, hydroelectric, etc can be used to do this. You're wasting energy, but you're never going to run out of wind. And the benefit is that now you have hydrogen which is essentially a mobile power source with excellent scalability potential (e.g. - you can't easily power a laptop on wind power). Moreover, there's a basically inexhaustible supply of hydrogen (I've read that it's the 3rd most abundant element on the Earth's surface).

In short, Ethanol, like any combustible fuel, requires huge infrastructure changes for development, manufacturing, and distribution. Hydrogen has the ability to STORE normal electrical energy that already has a huge infrastructure in place for distributing. Hydrogen will happen because there's absolutely nothing that can be done to stop it. It's just too economically attractive.

As mentioned before electrolysis of water to generate hydrogen does not make sense, because it requires several times more energy than simply charging batteries directly (with a distribution net that is already in place). Hydrogen is currently produced from carbon based fuels for very good reasons.
If for instance hydrogen was produced from sunlight directly then you'd have a nice solution on the table. Unfortunately this technology has not been invented yet.

Actually a gasoline or diesel pumpstation can easily be switched to pump ethanol or biodiesel. Hydrogen on the other hand needs to be highly pressurized, which means absolutely nothing of the current gasoline and diesel distribution net in place can be used.

Here's an interesting comparison between hydrogen and biodiesel.
http://www.unh.edu/p2/biodiesel/arti..._hydrogen.html

I wonder what mileage a biodiesel powered hybrid would get? 75mpg? 100mpg?
If one has a car that gets 100 mpg with essentially no pollution (particle filter and NOx reduction in place) why would hydrogen even be attractive?

Well, yeah, if you want to become dependent on a foreign country for fuel -- oh wait. I was more talking about the idea of making it ourselves. Land and the ability to farm it is not an inexhaustible source. You put a strain on the land in doing so. There's more than just the trucking aspect when it comes to making it.

Personally, if E85 became a standard I would be thrilled. If we could just get over the hump of the initial costs (hey, fancy ECON term -- diseconomies of scale) it seems to have a lot of potential. I personally don't see this ever happening because of politics and how the global economic market works. However, I wouldn't even mind importing tons of it from Brazil and then have car companies utilize the Flex technology that is quite simple and cheap to manufacture. It would keep us off our dependency of the oil producing countries temporarily while hydrogen research continued.

Will this happen? I have no idea. But hydrogen most certainly will because it has such a wide variety of uses in that it' can store electrical energy.

Nuclear plants could supply endless energy for hydrogen production and eliminate fossil usage all together.

Biodiesel would probably sell for $20/gal if it got 100mpg in a hybrid. And does'nt diesel pollute worse than any other fuel?

Again, I assert my point of using renewable energy for this cause. Electrolysis allows you to use water instead of finite fossil fuels which clearly has advantages. As far as charging batteries directly, batteries have memory issues, lose charge over time, and are bulky when considering the electrical potential they yield. Hydrogen can be produced from electrolysis using free materials and powered by renewable, pollutant-free systems -- why does it matter if it's a little (or a lot) wasteful?

In terms of ethanol and biodiesel, they require land. These are not free materials and they're certainly not inexhaustible. Yes, the resultant fuel is much more like gasoline in many ways and fits nicely into that infrastructure. However, hydrogen doesn't have to be pressurized into a liquid form. People are using IF's to encase hydrogen liquid into nice little batteries -- it's already been done.

In the end, hydrogen can and will be used for batteries. Ethanol or biodiesel may well be used in cars and houses in the next 5-10 years. I hope they do. However, hydrogen is coming because they are a quantum leap forward in battery technology. You can't power your laptop on bio-diesel and current batteries just don't cut it. That's why hydrogen is attractive.

I think some people here are lost in a ethanol vs hydrogen battle that I think is misplaced. I definitely think both will replace fossil fuel use in the future. I think ethanol is a first step to breaking the dependency on the Middle East....the then the long term fuel of the future needs to be hydrogen. The reason is the ethanol currently requires harvesting large amounts of crops for refining into fuel. As we all know, crops are variable, a bad year for corn would hurt fuel reserves. Only Hydrogen is viable as a fuel source for the ever increasing demand throughout the world. Fuel cells and advanced battery developments are not alternatives to fuel but rather advancements in technology. Whatever the future fuel source is, higher capacity battery systems capable of biologically re-engergizing will be used in conjunction with each other.

I think hydrogen is in it's infancy where ethanol and biodiesel have been around for a few decades. I think as far as infrastructure goes, current fueling stations can pump ethanol and mixtures such as E85 just as easily as gas. The way to get those stations to offer ethanol and E85 is through regulations placed on gas companies. You want to have a gas station in the US, then you need to offer gas, ethanol or E85, diesel and biodiesel. The gas companies are not going to make this change on their own.

There are lots of alternatives for 'free' energy that I hope comes to fruition. I watched a special on discovery about a company that is using fabrics to cover parking lots. Weaved into the fabric is photo voltaic cells which absorb energy from the sun. Then in front of the parking spaces is charge port that users can plug into their vehicle. Having you car parked outside all day at work on a sunny day, getting shade from the fabric roof, getting energy from the sun.....that will be amazing. And this is not just useful to electric cars because no matter what the fuel source is, the future of automobiles is hybrid powertrains. Electric only vehicles will never be viable just as fuel burning only will not be viable.......hybrids are here to stay.

I got sick of reading the first page so I didnt bother on reading the last 2, Hybrids are not ment to get better gas mileage superly, yes it does get a better gas mileage but they are designed to pollute less. And Hybrids get better gas mileage for those who are debating still in a city, rather then on the highway where its the opposite.

Roaddemon 02-08-2006 02:12 PM

From what I've read we export much more American oil than we keep here in the united states. Why we should be dependant on the middle east is beyond me. Maybe we get a better price for our oil overseas. And can import eastern oil for less.

MikeW 02-08-2006 02:13 PM

In the medium term the filling stations need 4 underground tanks for
Diesel D100
Bio-diesel B100
Ethanol E100 You will need E50 for -50 F starting ability
Gasoling G100-modern cars do not need that 10% ethanol for low emissions
and smart pumps that allow you to pick what you want.
'Today I feel like so B50' Look at the tools that bartenders have, they can mix water, syrup and other crap right at the spiggot.

So the pumps should be enhanced now. The chicago region has 87,89,93 at most places.
In the short term how about mixing 87&89 for 88, 87&93 for 90 89&93 for 91, so you can have 87,88,89,90,91,93. add a $0.05 for each step up. Not too damn hard is it?

Roaddemon 02-08-2006 03:52 PM

Anyway, US oil conservation won't lower gas prices at home because we are now a world importer and exporter of oil. Gas prices will depend on the world oil market price. Hybrid cars won't stop the world thirst for oil. Oil demand is going to keep increasing with the development of countries like China. Hybrids are good for clean air.

In order to get hydrogen into liquid form you have to supercool it (= very expensive) and insulate the tank. And even in liquid form hydrogen has 4 times less energy per volume than diesel:

Not with bio-diesel but with Methanol and I rather power my laptop with a methanol fuel cell since it has a higher energy density than a hydrogen fuel cell.

Hybrids get better mileage on highways as well and despite the extra weight of the batteries. Because their engines are designed to be more fuel efficient at partial throttle.

I don't see how they could charge $20/gal since customers would then simply switch to Diesel.
Diesels are pretty clean with low sulfur content (Biodiesel doesn't have any sulfur), particulate filters and urea injection to reduce NOx. The technology is available, but the EPA in the US does not enforce it.

A barrel of oil contains 6000 MJ of energy and the US consumes 20 Mio barrels per day. You would need 1500 nuclear plants running 24/7 in order to generate the same amount of energy! (Keep in mind the US only has 100 nuclear plants a this point).
Clearly, it's mainly an efficiency problem and not really a fuel issue.

saturn 02-08-2006 04:59 PM

globi, I appreciate your info, but you're not keeping it all in perspective. There are always multiple factors that have to be considered collectively. One energy source might be more abundant, but cost a million times more to get at. Another energy source may be more energy-dense per unit volume, but might be a billion times more rare.

Diesel comes from oil. End of story. It can be used in some capacity for certain applications, but it is by no means the next revolution. Hydrogen, while much less energy dense comes from water. Doesn't get much more free and abundant than that.

Methanol and ethanol come from crops, etc. There are issues with scalability in that you only have so much viable land and other resources. Again, it may be used in some capacity for certain applications. I agree with an earlier post that these two will have applications in the near future while hydrogen will come much later.

In reference to your Methanol fuel cell point, here's a blurb from a study done at Princeton. Now, I'm not one of those people that says, "I have a study I must be right". My goal is just to show you that you have to look at everything in totality. Just stating the most energy-dense material doesn't mean it's the best overall solution. There's a lot of things that still have to be done for any of this to become a reality. In the end, it might not be either solution for entirely political reasons. Who knows.

Methanol infrastructure capital costs should be low initially (less than $50 per car), but would increase to $330-770 per car one new methanol production capacity was needed. Hydrogen is the preferred fuel for fuel cell vehicles, for reason of vehicle design, cost and efficiency, as well as potential energy supply and environmental benefits (e.g. - the possibility for reduced total fuel cycle greenhouse gas emissions plus strictly zero tailpipe emissions). The capital cost of developing hydrogen refueling infrastructure is comparable to or less than the total cost (on and off the vehicle) for methanol or gasoline fuel cell vehicles.

Yes they get good mileage if your not dogging the throttle but still hybrid vehicles get better mileage in the city rather then highway I never said they get poor highway if thats how it came out sounding sorry .

Again read this link: http://www.unh.edu/p2/biodiesel/arti..._hydrogen.html
Diesel can be produced from algae or soy beans much more efficiently than hydrogen can be produced from anything (more efficiently means it uses less space as well). End of story. Again so far no-one has invented a technology to produce hydrogen on a large scale inexpensively and environmentally friendly. That does not mean it's not possible, but it means we are very far away from a viable solution at this point.

Actually I was refering to laptops and not to cars, when I mentioned the methanol fuel cell. The methanol fuel cell has another issue which the princeton study didn't even mention and actually makes this whole study somewhat ridiculous: Although a methanol fuell cell has a higher energy density it doesn't have the power density as of yet to power a car.

Also energy density is a huge issue if you need trucks to move from A to B:

I think the idea here is to get away from fossil based fuels, not totally eliminate them. Fossil fuels will always have thier value in the world.

Although hydrogen energy is less dense in it's natural form(water) there will eventually be technology that can economicaly extract it and compress it into a fuel cell with equal or greater energy than a gallon of gas. Multiply these cells till you get the desired mileage per charge. If this technology comes about Politics and oil companies may surpress it. It may already exist. What can be percieved can be achieved.
It is not beyond our minds and scientific capabilities.

Any boiodeisel fuel that gets 100 miles/ gal would be some very expensive stuff. It would no doubt negate any savings by it's high cost. Only advantage would be cleaner air and alternate fuel. My opinion only

Renesis_8 02-08-2006 07:34 PM

Mazda should use the rotary engine as an electricicity generator to power electric motors that powers the car. Have a really small rotary engine that runs on hydrogen to charge the batteries. It could get a really good milage/money, perhaps mileage to total energy used ratio, or i am just dreaming.

globi, I didn't realize you were talking about biodisel. When you mentioned the 4x energy density issue, I looked at the PDF and it seems as though you were referring to the diesel and biodiesel numbers. My bad.

I suppose in the end there's still a lot up in the air. I'd be surprised if some sort of bio-fuel wasn't in wide-scale use in the U.S. in the next 7-10 years. I don't think you realize I'm not disputing that. But hydrogen fuel cells will be a major reality if because of nothing more than the political hype that surrounds it. But I think we've beaten this topic to death and I'll leave it at that. I'll check back with you in 20 years and we can see what happens.

It's not the fuel that is more expensive. It is the combination of diesel engine with hybrid that would be more expensive. The initial costs of the car would be more expensive.

Let's face it, the reason why we don't see more hybrids is simply because oil is incredibly cheap. At this point there's no economical reason in the US to purchase a Hybrid/Gasoline or a Diesel powered car. (One could even say that Toyota was lucky and found enough people that have money to burn).

The reason why almost 50% of the cars in Europe have diesel engines is because oil is expensive enough to justify the extra costs of a diesel engine for economical reasons.

Of course if the US government would cut income taxes in favor of a gasoline tax it could indirectly support a more efficient economy WITHOUT increasing the total tax burden.
I don't know why people in general consider an extremely high income tax to be more fair than a relatively small gasoline tax.
