Rarpy - 13 Feb 2007 02:54 GMT Ever since the first patent in the 1930's, it seems people just want to debunk the idea of combusting hydrogen from water inside an internal combustion engine, but yet again it seems a company has produced the technology to make it happen:

Meanwhile the mafia known as the oil industry are making tens of billions more dollars every year and their pals in the dying US auto industry even now can't comprehend that consumers don't want gasoline-guzzlers.

In other words you and the Aquagen people are claiming that, in effect, more energy can be produced than that needed to produce it. I also note that it is an additive but if it worked that well, it wouled be a primary source of perpetual energy. Sorry, the world doesn't work that way. Can I sell you a slightly used bridge?

Never been in New Jersey. Never been an Exxon fan. However, with regard to any basic science, it appears that your calling me a moron, means that you think that I know more than you. That is right, Thank you.

The same technology that converts engines to run on natural gas can run hydrogen with some adjustment. Now, the big kicker is that hydrogen is very low octane, so something must be done about that. EGR in massive amounts is one solution.
Tankage is a problem- compressed hydrogen provides limited range as the size of the tank in cubic foot per megajoule of energy is large. And of course, as others are pointing out, electrolysis is not free- you need to put in as much or more energy than you get out.

Hydrogen is as good as gasoline for an EV of any kind, like HEV, PHEV, etc.

Fuel cells are fine too, but not the only way to use hydrogen.

HLS@nospam.nix - 14 Feb 2007 02:52 GMT > Fuel cells are fine for the space shuttle. No regular stiff can ever > afford them. Not quite true. Kristian Michelsens Institute had a contract to develop fuel cells, and I have personally seen the product. Small ( about a foot on each side), relatively inexpensive, and able to generage about 17 KWH. That would equate to roughly 20 horsepower ( dont flame me on decimal points, please), which is not a lot, but is enough for small cars. Remember what the old original VW used to produce?
There is no one answer. But it is my believe that as energy expenses begin to increase geometrically, we will have to do everything we can to stay in the game.
This bullshit about there being plenty of oil out there has to be rationalized. Yes, there is still a lot of oil and gas, but we own less and less of it.

The problem is, actually, that you consume more fossil fuel to run a car on hydrogen, whether you use an ICE or fuel cell, than you would if you had never made the hydrogen in the first place.

I have always said that hydrogen is a good fuel, but getting it cheaply is the problem. Transportation and storage are issues, but can be achieved, in time.

Another big issue is its miserable volumetric energy density. You can't just put the fuel tank under the boot/trunk with hydrogen !

It's the only current method that makes sense. What's the point of using a "fuel" that takes more energy to produce than it yields, and then pumping it into an ICE that gets what, maybe 25% efficiency? 30% on a good day? Might as well just burn gasoline, it's more efficient.

ICE efficiency is well known, for old cars it may be as low as 15 percent, some diesels and hybrids about 25 or 30 percent, and the monster engines as big as a house can get 40 or 50 percent, but they might not be good as power plants.

You seem uninformed about this.
The fact that hydrogen powered fuel cell cars may make sense may only be because fuel cell cars ARE electric cars.
The reason hybrids get good mileage is because they ARE electric cars. There needs to be more appreciation of the fact that electric cars are the future, whether they are gasoline hybrid electric, diesel hybrid electric, fuel cell electric, or plug-in electric.

You're right there Joe. Just the ability to reclaim their kinetic energy when braking makes them very attractive.
The other neat thing is that the ICE in a hybrid doesn't have to be sized for the peak power demand ( as when accelerating ) it only needs to be sized for the average power since the battery 'takes the strain'. Possibly no more than 20kW ( say 500cc ).

Might as well just burn gasoline, it's more efficient. Think outside the box, Nate. We can burn gasoline as long as we have it. We are now deficient in hydrocarbon energy production. Our cashews are in the hands of foreign governments. It is not a good situation.
Efficiency doesnt mean anything if you have to start walking to work. Inefficient energy processes then begin to take on importance.

WE (the USA) have a shortage of oil and gas. Yes, we can still buy it, import it, etc but the shortage here is real. Demands are being met, at present, but world consumption is still on a faster track than world oil discoveries.

If you're relying on a hydrogen-powered ICE, I'm still going to be walking to work, because it still needs fossil fuel input to the loop to power the electrolysis. The whole point is that using a fossil fuel to power electrolysis to create hydrogen to fuel an ICE is a hell of a lot less efficient than just burning the fossil fuel in the ICE directly.

That's simply not true. It is perfectly possible to power the electrolysis with renewable energy sources such as tidal, solar or wind power.

Energy from tide, solar and wind is so sparse and relatively expensive that wasting most of its value to produce hydrogen will *never* make sense.
Hydrogen from nuclear perhaps. Provided that there's the huge surplus of cheap energy to do it. They said electricity would be too cheap to meter in the 60s didn't they ?

Maybe it never will make commercial sense, but my point was that it does not require fossil fuels to power the electrolysis to make hydrogen.

And then they went and sold off the generating capacity to private entities who have no interest in really cheap electricity - other than gaining market share. Hydrogen from nuclear would be great - hydrogen from nuclear fusion plants would be even better but is long way off. I was in the JET reactor at Culham some years back and that was one hell of an impressive piece of kit. Shame it took more power to get it working than it could ever produce though. I hope the ITER project goes well.
Mind you - it all still misses the point (that i think you agree with) that however you get the hydrogen, it is more efficient just to use the electricity directly in the first place for all but a few applications.

What's the percentage of nuclear energy (not only electricity!) currently produced globally? How many hundred reactors do you want to build each year to provide enough hydrogen for the cars, how long will the uranium last *then*, and where do you buy it?

This has been beat to death for years. This is the real world:' http://eed.llnl.gov/flow/02flow.php
If you use wind to produce hydrogen then that wind won't displace coal. It has the same net effect as using coal.

Let's just say if you want hydrogen you need to go for a crash programme to build 1000 nuclear stations.

Let's say that your conversion process is 75% efficient (a number I just pulled out of my colon; I have no idea what the actual current practical maximum efficiency of electrolysis *is,* but I do know from basic chemistry that if it were 100% efficient that you would need to put in exactly as much power as you were planning on getting out, ASSuming you had a 100% efficient fuel cell) and that your ICE is 30% efficient (a generous estimate,) that means that not even counting transmission losses or transportation costs you're down to barely over 20% efficiency for the system as a whole - meaning for one equivalent of gallon of gasoline's energy that your car actually uses, you'd have input the equivalent of *FIVE* gallons of gasoline to the system to get to that point.
Now multiply by the number of hydrogen-powered ICE cars that you anticipate being on the roads, and tell me if we have that kind of generating capacity, and if we have the infrastructure to deal with that kind of load.
IMHO it'd be FAR better to concentrate our research on producing fuel cells that achieve high efficiencies, and even better if we can get them to run on fuels other than pure hydrogen (various alcohols would be nice; so would currently available fossil fuels) as then we can get vehicles that not only use their energy more efficiently, but can also take advantage of regenerative braking (being by necessity electric, neatly utilizing the developments already made with hybrid vehicles) for even greater efficiency than is possible with an ICE vehicle.
Another good place to concentrate research would be in electrical energy storage, either through a chemically reversible fuel cell (ideal, but probably impractical) or batteries or ultracapacitors with higher than currently available energy densities - due to the fact stated above that a fuel cell vehicle would by necessity use an electric motor for its motive power, and therefore regen. braking is a logical next step.
Unfortunately, nothing will replace the sheer wood-inducing factor of a well-tuned, nearly-overcammed V8 shaking and spitting at idle, or the glorious howl of the same engine sucking in great whacks of atmosphere at 6500 RPM, but I guess that is something we're going to have to get used to :(

I fully agree with you. They key is in getting the energy density high enough and developing a fast refueling system that has the same time benefits as gasoline.

A quick back of the envelope calculation will confirm that it would require several times the electricity generating capacity that we already have, if not an order of magnitude. You really think that it is even POSSIBLE never mind practical to suddenly produce the same amount of electricity that we're already producing (or several times that,) solely from renewable sources? This is why efficiency is of paramount importance when we're talking about a paradigm shift away from fossil-fuel powered ICEs.

A tank full of hydrogen produced by electrolysis might conceivably weigh less than a bank of batteries that stores the same amount of energy (I don't actually *know* this to be a fact, but the fact that research continues with hydrogen would lead me to believe that that is the case.)

I still like the idea of an alcohol-fueled fuel cell. There's no physical law that says that you can't grow something and then ferment it to produce alcohol and use less energy than the alcohol yields - that's the appeal, there.

No, of course not - and most certainly not suddenly. And I think we're talking at crossed purposes here - and actually in agreement. My point was that it is perfectly possible to use renewable energy sources to power electrolysis, not that we could do it tomorrow (although we can do it today on a small scale) or that we could do it on a scale that would replace the gasoline economy, or that it was particularly efficient.

Even without the need for renewable and sustainable and affordable fuels, the gasoline ICE should have been phased out long ago.
To tell just how bad the ICE is, think of a big V8, turning at 600 RPM, that is 10 revolutions per second, and 80 pistons being pushed down every time the engine turns twice, or 40 power strokes per second. Chances are it will stall, 40 power strokes per second, 2400 per minute, will not keep the engine running.
An electric motor doesn't use any fuel while standing, and will produce more torque at low RPM from a standing start.
Don't confuse the horsepower issue with low RPM torque, horsepower increases with the RPM and speed.
For city driving, torque is needed, not horsepower, and very little horsepower is needed for cruising at road speeds.
To accelerate, the ICE must ask the transmission to downshift so the ICE can turn faster at a lower gear ratio, wasting fuel, while the electric motor can produce substantially more torque without downshifting.
Joe Fischer
Steve - 15 Feb 2007 14:51 GMT >>.......... >> [quoted text clipped - 11 lines] > and affordable fuels, the gasoline ICE should have been > phased out long ago. Why? As of right now, a hybrid gasoline (or diesel) is the most efficient way to move a car around. Pure electric doesn't match the overall efficiency because charging batteries is and powerplant efficiency combined can't match the peak efficiency of the ICE that you so casually and stupidly dismiss. Chemical-to-mechanical efficiency of ~40% in a portable package is NOT something to be sneezed at, its quite impressive, actually.

What a load of crap!! The current Chrysler 5.7L ("new Hemi") v8 idles between 400-500 RPM to maximize efficiency, and it does so perfectly well without stalling. Just for grins, I've idled even '60s vintage v8s down to 300 RPM or so. That's not practical because the low idle speed would eventually cause camshaft damage in those cars, but with roller cams its perfectly reasonable to idle a v8 down around 300-500 RPM in a modern vehicle. The factory recommended idle speed on 60s and 70s v8s (except the high-performance ones with more radical cams) was around 600 rpm.
Get a clue before you post garbage.

The cost of electricity obviously is less per mile than gasoline here, hybrid or not (6 cents).
If hybrids would have been phased in beginning in 1974, things would be a lot better now, but by the time the change is made, battery and ultracapacitor, fuel cells, and flow battery technology may have progressed to the point that the ICE is gone.

If all autos were hybrid, I would not be writing this, but they are not, and there doesn't even seem to be any real hurry to make the change. I just junked a 5.0L 1988 d'elegance, because the engine was such a dog, the carb was a monstrosity of confused engineering of vacuum hose and two electrical connections of 3 or 4 wires each.
I want an electric car so bad, quite, no stinky fuel, less grease and grime, and they have to be easier to work on.

Battery technology and electronic controls have come a long way since 1974. Hybrids weren't practical then.
>>> To tell just how bad the ICE is, think of a big V8, >> [quoted text clipped - 3 lines] > but I am tired of the things, I don't need the ability to turn > at 5500 RPM to accelerate. It's called "reserve power" and it can save your butt in a sticky situation. This is not a downside to either ICE or electric though, an electric can move just as smartly, it just doesn't have the same range.
>>>turning at 600 RPM, that is 10 revolutions per second, >>>and 80 pistons being pushed down every time the [quoted text clipped - 17 lines] > all the idle speed recovery vacuum solenoids and > electronics, stalls are bad in traffic. True, but there's nothing keeping even an old engine if well maintained from idling at factory spec. Usually if it won't, the remedy is a proper carb rebuild (including rebushing the throttle shafts, which a lot of "rebuilders" don't do. To get a proper rebuild, you generally have to send your carb away to a specialty carb shop, not have your local mechanic throw a jiffy kit in it or buy a "reman" from your FLAPS) and then everything is back to normal.
>>That's not practical because the low idle speed >>would eventually cause camshaft damage in those cars, but with roller [quoted text clipped - 12 lines] > and the engine to not try to pull too hard waiting for a > light in gear, yet not stalling. There's a solution to that problem, it's called a "manual transmission." Even so, if an engine is pulling against the brakes at a stop light, the idle speed is set too high and needs to be lowered. If it can't be set that way, there is a problem with the engine management, or else the torque converter is too tight.

Sure, as long as you don't ever travel more than 100 miles away from home and don't mind letting the car recharge overnight after each medium-long trip. And that is perfectly practical for *some* people and I imagine that as the price of gasoline goes up, we may see more and more mainstream pure electric vehicles.

Well, Nate, what your going to get in the future with transportation is something along the following:
As fuel prices continue to rise, people are going to turn to the cheaper solutions.
First, they are going to move to where they work. Second they are going to start shopping close to home. Third they are going to take vacations closer.
Then when prices continue to rise they are going to start getting on mass transit. Then they are going to push the government into subsidizing mass transit more and more. Your going to see more and more rail built. More and more bus traffic.
As for the problems of hydrogen and batteries and all that, it's immaterial. All of these problems are the result of designing transportation that has an -independent- and -mobile- fuel supply.
Rail has no such limitations. You can design a cross-country "bullet train" that runs on electrical power, and goes 200Mph and the power is supplied by transmission lines that go 500 miles across country to the coal-fired power plant and are coupled to the train engine by contacts, just like a subway train today.
Sure, that will make taking a trip across country take 4 times longer than a plane ride.
But when fuel prices push the cost of the plane ride to 15 times the cost, everyone will get on the train except for some select few.
The losers in all of this are going to be the rural people. What your going to end up seeing is all of the small towns that can't afford to put in mass transit will dry up and disappear. People are going to end up in mega-cities because it will be cheaper to live close together. The only folks left out in the rural areas will be the real commercial farmers. And they will be producing thier own liquid fuel, alcohol.
Most long haul freight will end up on rail
Most short-haul freight distribution will be biodiesel-powered.
Electrical generation capacity will vastly increase. It will either be wind generation or nuclear.
What people always overlook in these discussions is that since it's going to be impossible to get cheap energy out of nothing, society will change.
150 years ago, there were no personal autos. Society worked out quite well without them. When personal autos came in, society radically adapted and changed from the form that it WAS in, to the form that it IS in today. When the personal autos go the way of the dinosaur, society will change to a new form THEN that is different than what we have NOW.
Someone from the 1800's, adapted to that society, couldn't possibly conceive of our society now. And if he could, he very likely would dislike it very much.
Someone from today, adapted to today's society, cannot really conceive of society in the future. And if he could, he is most likely going to dislike it.
Do I like thinking that one day, I might have to give up my cars and motorcycles and be dependent on mass-transit? f.ck no. But, my children's, children, who will be raised from infancy in a world without personal transportation, won't see their society as wrong. Most likely, they will read in the history books and be mystifyed about why people made such a big deal about cars.
Today, we tie in personal transportation to this notion of personal freedom. Without personal transportation, we feel like we are in jail, trapped.
But I ask you - does a 15 year old in the middle of New York City, who has no drivers license, but has a subway pass, have any less freedom than an adult in the same city, who has a drivers license and a car? Well, I've been in NYC and I can assure you, he doesen't. He can go anywhere that anyone would want to go in a car, on rail and on his feet. It just takes a little longer.

I cannot remember the last time I had a car "stall in traffic." Or stall ANYWHERE for that matter, unless I was a goob and dumped the clutch too quickly. Stalling cars are a thing of the past. And since when do cars have "idle speed recovery vacuum solenoids?!?" About 1975???
> I want an electric car so bad, quite, no stinky > fuel, less grease and grime, and they have to be > easier to work on. Yeah, just a few hundred pounds of heavy metals and corrosive electrolytes. Oh, and increase power grid capacity by 200% to charge everyones electric car. Oh, and all the safeties that have to be built into large battery packs to prevent cell reversals and other "rapid disassembly with report and heat" events in NORMAL operations, let alone what happens in a collision. No big deal at all. :-/

Additionally, a higher percentage of the SFHs in europe are attached townhouse type units than here, and of the single family detatched units, a VASTLY higher percentage sit on lots that are less than half the size compared to the high energy countries (US, Canada, Australia). 5 minutes with google earth is more than enough to see the differences between european and us land uses.

In Shaker Heights, Ohio there are thousands of big homes, rather mansions, 20 rooms or more, all built by millionaires in the first half of the 20th century or earlier, most brick, covered with ivy, and a lot of them were converted to apartments beginning in the 1960s.

Putting all your eggs in one basket is an evolutionary dead-end. there is more than one city :) I can't really debate that cities run somewhat counter to how humans are wired to best enjoy life, having tried both lifestyles. however, the normal response for people in the city is to make a small group of close friends. that seems to work pretty well. High crime rates are a separate issue, mostly relating to cultural issues in the us and a few other countries. MANY countries have highly urbanized living conditions and remarkably low crime rates. Again, it's a bit of a frontier thing, americans are kind of a rebel culture prone to glorifying crime.

Humans are supposedly 'wired' to co-exist best in groups of 7-12 and villages of 60-100.

Oh, some day our level of technology may be such that some guy (though he may not quite be human) will remark that slamming hydrogen atoms together to get energy and helium is "inelegant." But the stars will continue burn by fusion despite its "inelegance." :-)

And its not for lack of TRYING to replace reciprocating engines. The wankel was a bust for all practical purposes. The gas turbine doesn't scale down to automobile sizes well.
