Title: Hydro electric cars coming earlier than expected? Post by: Croosch on June 23, 2004, 07:28:27 pm Hydro electric cars coming earlier than expected?
Here's part of the article written by: Miguel Llanos If you can?t wait five, 10 or 20 years for the much-touted "hydrogen economy," then step right up: Several companies are ready to sell you vehicles that run on the fuel that's much cleaner and gets higher mileage than gasoline or diesel. Like sports cars? There's a Shelby Cobra with a 351 engine that runs on hydrogen. How about a Nissan Frontier pickup powered by fuel cells and hydrogen? That will soon be available. Or hankering for a hydrogen Hummer? That, too, can be yours. The article can be found at http://www.msnbc.msn.com/id/4563676/ A war over gasoline/oil and hyrdo powered cars are coming so soon, though they do cost a lot right now, in the future (like Hybrid cars) Hydro cars will also go down in price.

BOOM! BANG!
Title: Re:Hydro electric cars coming earlier than expected? Post by: Croosch on June 23, 2004, 08:45:38 pm Actuall, if you read the article I believe it sais what the engines are. If it can move the hummer nicely I don't think it's pussy.

Title: Re:Hydro electric cars coming earlier than expected? Post by: BTs_Mysterio on June 24, 2004, 12:35:58 am Does it have BOOM OMPH POW or not? And yes I know what the sound is form but shhh.

what if the hydro electric was more of a POP car? Title: Re:Hydro electric cars coming earlier than expected? Post by: one one one on June 24, 2004, 03:54:41 am um...I don't think it'll happen that fast...I mean they still need to figure out how to "collect" hydrogen and put it into cars...and also, I read somewhere they're putting lots of money into research in that and it might be a failure like when they tried to do solar cars...or something like that

Quote What do you think hydrogen is? well please explain exactly how a hydrogen engine works, i didn't even know they were using pistons because of the wasted energy from changing the momentum of them. Title: Re:Hydro electric cars coming earlier than expected? Post by: BFG on June 24, 2004, 02:35:03 pm As a general rule, no engine can function using hydrogen alone. Every form of combustion requires two substances to function: a fuel and an oxidizer. In most cases, the oxidizer is air. For example, an automobile engine creates a mixture of gasoline (the fuel) and air (the oxidizer) that is burned to release energy while a jet engine mixes jet fuel and air to produce the same result. A rocket is somewhat different since it carries both the fuel and oxidizer aboard. A liquid rocket typically burns a mixture of liquid hydrogen and liquid oxygen to generate thrust. While many potential mixtures exist for solid rockets, a common propellant is made up of a solidified piece of hydrocarbon with small chunks of oxidizing salts mixed in. Once ignited, the hydrogen and oxygen are released from their chemical bonds, mix, and are burned to produce energy.
A hydrogen engine does not use only hydrogen. The hydrogen is only the fuel, and it requires some form of oxidizer to undergo combustion. Depending on the application, the hydrogen may be mixed with air and combusted similarly to a jet engine, or the hydrogen could be carried in liquid form and mixed with liquid oxygen that would also be carried aboard the vehicle. There is a team in Newzeland working on a hydrogen engine: Quote As hydrogen is much hotter than our present fuels, we are looking to turn this into an advantage rather than a problem (as it has been considered in ordinary internal combustion engines, causing an overheating of valves). What we propose with our rotary engine is to use this higher temperature of the hydrogen as a catalyst or trigger. We use water injection along with a small amount of hydrogen. On igniting, the heat turns the water vapor into high pressure steam on each power stroke. We are not looking at power being derived from the hydrogen. It will be from the steam with the hydrogen as the internal heat source. This being the reverse of the present steam engine, where a large body of water is heated externally. We use a small body of water internally. To dissociate the hydrogen and oxygen in water without electrolysis requires a temperature of 800 degrees F. Water per volume expands 1700 times during that change, exerting tremendous force. This force is elastic, not like the hammer blows of the internal combustion engine. The diesel engine obtains its heat from high compression of the air reaching temperatures of 1000 degrees or more. This though, creates back pressure which is power loss on the up stroke. With hydrogen and water we eliminate this. I cannot use the term "stroke" as we have no piston, a round rotor revolves in a circle in one direction.

BMW 750hl (http://www.bmwworld.com/models/750hl.htm) This article provides further information about the BMW 750hl and about hydrogen powered cars in general. Valvoline.com-BMW's 750hL Sedan (http://www.valvoline.com/carcare/articleviewer.asp?pg=dsm20011101bh) >>> Simply, liquid hydrogen and oxygen are introduced through fuel injectors into a 750hL variant's cylinders the same way as gasoline and oxygen are in a conventional BMW. The end result, however, is quite different in that the hydrogen version produces almost no tailpipe emissions. That said, it also produces significantly less horsepower. The bi-fuel engine is optimized to run on either gasoline or hydrogen fuels, which is to say it doesn't achieve maximum performance from either. That's simply the necessity when configuring an engine to run on two fuels as disparate as gasoline and hydrogen, which possess significantly different combustion characteristics. In bi-fuel form the 750hL puts out 204 horsepower, substantially less than the 326 hp produced by the 7 Series' conventional gasoline 5.4-liter V-12. However, BMW says a dedicated hydrogen version will produce an impressive 380 horsepower when optimized exclusively for this fuel?something that gives hope for those into both performance and environmental sensibility. This isn't to say the bi-fuel hydrogen 750hL is a slacker. Yes, its output is more in line with that of a 3.0-liter six-cylinder engine in a 330xi than a 5.4-liter V-12 in a 7 Series, and it's nearly three seconds slower than a conventional 750iL in a 0-60 mph jaunt. But on balance, this is something less noticed in a luxury-oriented 7 Series than in one of BMW's more performance-oriented models. Overall, the hydrogen-powered 750hL does a good job of motivating down the road without overt signs it's running along on environment-friendly rocket fuel. <<< It's worth noting that this car was made back in 2001. Hydrogen conversion kits are also becoming available. http://www.unitednuclear.com/h2.htm (http://www.unitednuclear.com/h2.htm) The technology is there, we just need to use it.

WRONG. Fucking read my post next time goddamnit. I spend part of my day edjumacating you dumbasses and you don't even bother to read what I wrote.

keep your temper in check, it will suit you better. Title: Re:Hydro electric cars coming earlier than expected?

Thank you for admitting that you didn't read my post and were talking out of your ass about shit you know nothing about. And my temper is quite in check, but thanks for asking. Believe me, you'll KNOW when I lose my temper. |
