hydrogen is sort of dangerous to transport.......


and yes, i think hybrid tech will be around for a very very very very long time
Yes but so is 30 gallons of gasoline in an SUV, hundreds of gallons of nuclear waste, or 5,000 gallons of jet fuel on an airplane. But think about the nuclear waste... they engineer special containters that can pretty much stand up to anything. I can't imagine they wouldn't use the same technology into their tanks.

Use nuclear power to extract it. It's the cleaner of most technologies and has come a long way since the 3 mile island days. We'll have a lot of the "not in my backyard" problems though. Heck, re-use decomissioned nuke subs parked at the dock to suck in seawater and extract it right there! Bury the waste in that hole in Nevada or Norway or wherever and put a ziplock top on it.

Now the political answer: Then we can get off most fossils fuels and withdrawl completely from the middle east and supply our remaining needs with domestic sources. Then, per their wishes, they can go back to the stone age since they do anything and don't contribute to anything productive in the world except digging holes in the ground (oh yeah the "Evil West" provides that expertise to them) and they will have no source for income. Everyone will be happy then right?

No it does not, the hydrogen is harvested from the FOSSIL FUELS which generally have CH bonds and thereby the Hydrogen is harvested and the carbon burned off. I never said it is made by using water as the energy source, I said that the hydrogen could be harvested from water, as opposed to being harvested from hydrocarbons which is a scientific synonym for gas/oil etc...

You completely misquoted/misunderstood me I never said hydrogen was made by using water as the energy source to extract the hydrogen, infact water is a biproduct of hydrogen fuel cells.
Sorry, I didn't realize that fossil fuels contained hydrogen. That being said, I havn't been able to find anything as far as fossil fuels being "burned" to extract the hydrogen (ok, I'll admit I didn't spend much time looking into how this is actually done). It could be possible though nor would I try to dispute it - if you have a source, I would be interested in reading it. http://www.lanl.gov/orgs/pa/newsbulletin/2003/12/03/includes/text02.inc

Also, I think you should read myth#12 which concerns obtaining hydrogen fom fossil fuels.

Wishful thinking. too many safety risks and ofcourse nuclear fuel is also in limited supply...

The myth #12 actually admits that hydrogen is obtained from fossil fuels, and it goes on to use biomass as a possible second use. However keep in mind that the biomass uses fertilizer to be grown and it uses fossil fuels to be transformed and transported which far outweighs its benefits. The website on the oil crash, if you look into the scientific aspects of it, it makes complete sence. You don't have to worry about and go crazy that oil is going to peak, but at least look at the facts surrounding pertoleum replacement.

Apparently, the polution in NY is getting to your head. Notice my prior post!

- also, where is the pollution part? The other link talks about 0 emmision hydrogen development from fossil fuels.

Yes, it is stating that hydrogen can be obtained from fossil fuels [rolleyes]


Also, I do not buy into the whole "we only have oil for 50 more years" crap (though the oil grades may be an issue - such as oil from Indonesia can be used as lubricants but not gasoline). New oil supplies are constanly being found (e.g. Russian oil supplies that may be larger than Sadi Arabia's within the last year)

EDITED:
Also - the by product of fossil fuel hydrogen extraction is CO2 - I guess we should all just quit breathing as well.

BMW seems to be the only auto company that I can find that is looking towards renewable resources for it's hydrogen technology. Chryster is looking at powerballs made of Borax, and I can't find much of anything on the other companies other than some are looking at a sponge like device using hydrogen to begin with or reformers using natural gas, or methonol.

Alternative engines.
In the area of alternative engines, the BMW Group is investing in the hydrogen combustion engine as the engine concept of the future. In comparison to fuel cells, the hydrogen combustion engine has a higher power density, lower costs and the usual driving dynamics. To guarantee the individual mobility of customers over the long term as well as reduce emissions, especially carbon dioxide emissions, the BMW Group is focusing on hydrogen generated from renewable energy sources.

Plus, if the exhaust is water vapor, wouldn't that affect precipitation? I've never heard anyone bring that up.

I never said anything about pollution whatsoever, all I said was that the hydrogen is obtained from fossil fuels. This isn't an issue, perhaps the big smoke stacks pollution of the midwest is getting to your head? [nutkick]

P.S. I don't believe the oil is going to peak either, but at least realize the sources cited on hydrogen power are credible...

Exactly, we can all feel proud that the $$$ well spent on our bimmers is being used to pioneer the way for clean energy in the future. Go BMW [bmwdance]

Umm, a while back some crazy scientist created a radio that tuned into something that no one can figure out now but he got so much power from that little radio that he was able to run all of his appliences in the house from it. He wrote a book about it and was killed. The Japanese tried to get it but couldn't, the soviets tried to get it but couldn't, KGB got mad and one of their agents smashed up the whole radio after killing the scientist. That book still exists and a friend of mine was trying to get it for 3 years, finally got it (there are 17 copys circulating libraries in the entire world) and he is now in the middle of reading it. Too bad one of the pages does not contain a schematic on how to build it or all of these problems would be solved.

Edit: I think the book is called something along the lines of "The sea of electrons in which the earth floats".

Need I remind you of the Pinto fiasco???


There is no easy solution to the problem until we find a way of harnessing energy other than from burning fossil fuels or using nuclear power. Some sort of super-efficient solar panel might be the way to go - We may as well use the free energy from the sun as it is just going to waste otherwise. problem is of course cost and efficiencies. same old, same old.

Oh, and keep the conspiracy theories for Truth magazine. [8)]

Pinto fiasco? Conspiracy theories? WTF are you talking about??? That has nothing to do with what i posted. Nuclear energy is the most efficient energy we have right now. We just don't know what to do with our waste.

I was doing some patent and trademark research today for a project I am working on. Out of curiousity I search the database for recent patents with the keyword BMW. As expected a whole bunch came up. But this one is brand new and highly pertinent to this thread.

A patent was issued to Robert Bosch for :

Method and device for operating an internal combustion engine using a plurality of fuels

Abstract

A method for operating an internal combustion engine is provided, such as, for example, in a motor vehicle, in which at least two different fuels are simultaneously supplied to at least one combustion chamber of the internal combustion engine.
......

Note the word SIMULTANEOUSLY!! - If you want to see the patent - Patent

.......
BACKGROUND INFORMATION

In conventional bi-fuel systems, an internal combustion engine may alternatively be operated either with only a first fuel or with only a second fuel.

It may be desirable, such as, for example, in the field of automotive technology, not only to reduce the pollutant emission on the basis of the fuel choice, but also to extend the range of the vehicle on one tank filling. This range may be required to be large enough so as not to limit the mobility of the motor vehicle on the basis of an existing fuel-supply network.

For this purpose, an EXPO.TM. vehicle of the BMW AG company may be alternatively operated using fuel or pure hydrogen. The switchover between exclusive fuel operation and exclusive hydrogen operation may be implemented by the driver.

In exclusive hydrogen operation, CO2--, CO-- and HC-emissions do not occur. Furthermore, the NO.sub.X emission may be greatly reduced. However, the number of service stations providing hydrogen may be few, such as, for example, in rural areas, so that the mobility of the vehicle in exclusive hydrogen operation may be limited as a result. In contrast, in exclusive gasoline operation, the existing comprehensive supply network may be utilized. However, in exclusive gasoline operation, the pollutant emission is considerably higher than in pure hydrogen operation.
