Quoting from March/April 2007 Technology Review
In the context of the overall energy economy, a car like the BMW Hydrogen 7 would probably produce far more carbon dioxide emissions than gasoline-powered cars available today. And changing this calculation would take multiple breakthroughs--which study after study has predicted will take decades, if they arrive at all. In fact, the Hydrogen 7 and its hydrogen-fuel-cell cousins are, in many ways, simply flashy distractions produced by automakers who should be taking stronger immediate action to reduce the greenhouse-gas emissions of their cars.
"Top executives from General Motors Corp. and Toyota Motor Corp. Tuesday expressed doubts about the viability of hydrogen fuel cells for mass-market production in the near term and suggested their companies are now betting that electric cars will prove to be a better way to reduce fuel consumption and cut tailpipe emissions on a large scale." In addition, Ballard Power Systems, a leading developer of hydrogen vehicle technology, pulled out of the Hydrogen vehicle business in late 2007. Research Capital analyst Jon Hykawy concluded that Ballard saw the industry going nowhere and said: "In my view, the hydrogen car was never alive. The problem was never could you build a fuel cell that would consume hydrogen, produce electricity, and fit in a car. The problem was always, can you make hydrogen fuel at a price point that makes any sense to anybody. And the answer to that to date has been no."

Someone is not thinking logically here. If you're burning hydrogen, how does the carbon get there??? By OSMOSIS????? and from The Wall Street Journal March 5, 2008

Here is info on the BMW'S HYDROGEN 7 http://www.spiegel.de/international/...448648,00.html Another comment about the BMW'S HYDROGEN 7 can be found at http://www.wired.com/cars/energy/news/2006/11/72100
"One major challenge is how to keep the hydrogen cooled to minus 253 degrees Celsius (minus 423 degrees Fahrenheit) so it remains in liquid form without boiling off. Despite the double-walled, stainless-steel tank that stores the liquid in high-vacuum conditions with aluminum reflective foil, the liquid hydrogen in the 8-kilogram fuel tank begins to boil after 17 hours if the car remains parked. The tank empties completely after 10 to 12 days."
At $10.30 per kilogram, hydrogen fuel is no bargain, even in Europe, where gas prices are significantly higher than in the United States. Filling up a 74-liter gas tank in Germany with high-test gas costs about $123, which for a cruising range of 300 miles is a much better deal than $82.40 you'll pay to go 120 miles on hydrogen fuel. The price of hydrogen is astronomical compared to the $2.20 or so per gallon price in the United States. However, BMW representatives on hand for the car demonstration in Berlin last week said hydrogen pump prices should be significantly lower if production increases for use as car fuel.
The automaker concedes its Hydrogen 7 production car is just a start. The model's acceleration and mileage pale in comparison with many ethanol-fueled and gas-electric-hybrid models, such as the latest Lexus hybrid. Company engineers are working to introduce lower pressure in the fuel tank to limit how fast the liquid hydrogen boils off. And they're researching new materials for a lighter and less bulky fuel tank.

Among the more hydrogenrich metal hydrides, volume is not the primary issue (Figure 3). In fact, many hydrides, including LaNi5H6, store more hydrogen per unit volume than does liquid hydrogen. Furthermore, at modest hydrogen pressures (a few bars), LaNi5H6 releases hydrogen at or near room temperature. Its hydriding kinetics are also acceptable, and laboratory quantities can be dehydrided and rehydrided in 5 to 10 min. The main challenge of metal hydrides is their weight. Because the hydrogen content of LaNi5H6 is only 1.4% by weight (wt%), storing 5 kg of hydrogen would require 360 kg of LaNi5H6.

But, it does not mean that hydrogen isn't a viable source of energy.

Windwalker, If you have the answer(s) I'm sure BMW (as well as any other auto company) would love to put you on the payroll at a nice fat paycheck. Every company I have ever worked for was alway on the look-out for new ideas and I am sure the auto industry is no exception.
Just like your claim of producing hydrogen with an efficiency factor of 1000%. If it can be done then contact a hydrogen producer with your idea. I'm sure they would love to increase their production at a lower cost. However, I suspect they have seen it and rejected the idea. Everything I have read about hydrogen vehicles I don't think it is the answer. At best it might be a stop gap approach but not the best concept. In my mind I see the electric vehicle as a better approach. Possibly with fuel cell to directly power the motor(s). None of the problems like hydrogen powered vehicles. One last point about hydrogen vehicles would be the restriction of their use in tunnels. Anyway you look at it hydrogen is a explosive element and in the event of an accident it could explode. kc0iv

I'm sure they would love to increase their production at a lower cost. However, I suspect they have seen it and rejected the idea. I doubt it seriously. If they had, they would have already put it into wide-spread use. The equipment IS in popular use, but the configuration is not. It's because electricians and electronics have two different approaches to the same thing. Electronics uses the configuration in millions, and even billions of places every day. Electricians don't even recognize it. In electronics, current flow is from Negative to Positive. And electricians see current flow from Positive to Negative.

And, which pick-up was it that was made with the tank outside the frame for a few years. They woud also explode on side impact. I think it was a GM model. Your argument is invalid.

With our current class-8 engines in the trucks, it would be possible to have a means of storing hydrogen on-board, and only using diesel fuel to idle. By injecting hydrogen to provide power (like they do with compressed natural gas in the Los Angeles City Busses), we could have a very serious reduction in the demand on oil and producing greenhouse gases. The driver should not have to "GET IT IN THE SHORTS".

There are systems on the market for both cars and trucks to inject propane into the engine to assist combustion.
Same idea as the CNG assisted engines. There are also claims that using a simple system to make Browns Gas (HHO, also known as HydrOxy) and inject it will help with more complete combustion and increase fuel mileage. There are shade tree inventors all over the place working on different systems to help reduce oil dependency. Some of them are nut-jobs, others seem to have good ideas that are viable. It'll be interesting to watch the various ideas for which one works and if any of them truly get accepted in a large market.

But, do a search on "hydrogen powered truck" and you'll come up with a company in Canada that adds units on a truck, and I believe the price tag starts at about $14,000. They claim to give a truck about 5% better fuel economy, but reduce the solid particle emission by 30%. My best guess is that this would be something like a "Joe Cell" and produces the HHO you mentioned. With the additional oxygen, I can see reducing the solid particles by burning them inside the cylinders, but I also wonder about the cooling system with the additional oxygen in combustion. I would expect it to cause a bit warmer operation.

Well Windwalker I've been involved in electronic for over 50 years and understand the difference between hole flow vs electron flow. Both are valid and it makes no difference which one a person uses the end results will be the same. You will also find most engineers use hole flow not electron flow.
As someone that has worked as an electrician, a electronic tech, and as an engineer I think I have a good grasp on the world of electricity and I'd be interest in what circuit could be used to improve a circuit's power requirement by 1000%. Maybe you could share this concept with me. Or at least show me some of these millions that use this configuration. I agree there isn't a easy answer for the transportation industry. And I don't see a major break through happening in the near future. As a guy and I was talking about solar a few weeks ago. He was pushing solar as the way to go. Since he lived in southern CA where the sun shines most of the time it works great for him. However, in the Midwest we have to many cloudy days for them to be effective. I see the same thing in the transportation industry one size won't fit all needs. I'm not naive enough to believe that hydrogen is the only explosive element. However, you will find many areas in the country with propane powered vehicle are not allowed in tunnels. Your example of the Chesapeake Bay Bridge-tunnel is interesting. Reading from the Chesapeake Bay Bridge Tunnel regulations
COMPRESSED GAS REGULATIONS
For Non-Commercial Vehicles Maximum capacity: (a) Not more than two non-permanently mounted containers having maximum individual capacity of 105 pounds water capacity or 45 pounds LP-Gas each, or one container having maximum capacity of 60 pounds LP-Gas, or (b) not more than two permanently mounted containers having maximum total capacity of 200 gallons water capacity LP-Gas when used as a motor fuel. Tanks must meet the approved standards of the Department of Transportation and are subject to inspection at toll plaza. They must be properly secured and valves closed while crossing the facility. A discussion on the Ford Pinto is an interesting one. I found on at: http://www.wfu.edu/~palmitar/Law&Val...ett-pinto.html written by a law professor. I wonder what the lawyers would do if they had a lawsuit involving a hydrogen powered vehicles. kc0iv |
