Hybrid Powertrains and Hydrogen Fuel Cells
An Anonymous Coward writes "Nice article from cars.com detailing a panel dicussion with reps from Chrysler Group, Ford, General Motors and American Honda agreeing that hybrid powertrains and hydrogen fuel cells are the future of automotive propulsion, and discussing their companies' different approaches in both areas."
It may be interesting to some of you that Honda is releasing (for its 2003 model year) a hydrid version of its Honda Civic, named Honda Civic Hybrid. It is a four-door sedan with gas mileage in the upper-40s / lower-50s.
This proves that electric hydrids are not only available technologically-speaking, but that they are commercially viable. Now imagine what would happen if a tax break (perhaps coinciding with George W. Bush's huge breaks) were offered for electric hybrid vehicles. It would stimulate the economy _and_ lower taxes. Of course, the oil industry wouldn't be too happy because of lower profits. Boo-hoo. Gas mileage has been going _down_ since 1986, when it peaked in the upper-20s (about 29).
BTW, you might want to read a review of the Honda Civic.
Despite folks who see hydrogen as free, current process require significant amounts of energy to get at hydrogen.
This article was posted on slashdot last week..
"The most promising source of the hydrogen may be geological "traps" similar to those now drilled for natural gas. Professor Freund said: "One of these natural hydrogen fields is already known to exist in North America, and extends from Canada to Kansas."
Apparently mining these geological "traps" would be no more energy intensive then current natural gas mining. And with such a vast supply right here in the United States, it like this is an inevitable migration.
I wonder If the oil companies are starting to look into hydrogen as the next money maker. They have the infrastructure (gas stations, transportation) to do it, it seems like it would be a no brainier to jump right in.
On Tuesday I bought a Toyota Prius, mentioned in the article. Very nice car for the dollar. Hybrid gas/electric car, uses the gas engine only when needed. In fact, I still haven't gotten used to the fact that the onboard computer will actually turn off the engine while driving, when it is not needed.
Gas mileage on the sticker is very impressive. 52 city, 45 highway. No, that is not a typo. It actually performs better in traffic, mostly because slow acceleration is almost exclusively under electric power. Coasting and deceleration use regenerative braking to recharge the battery, meaning you never have to plug the car into an external power source.
This car is the perfect geek toy -- many functions are performed via the touchscreen LCD screen, and all the other displays are 100% digital. Sound system is very good for a stock system, and you gotta love the static cling sticker on the back: Eat my voltage.
Sticker price was about $21k, and from my experience, has been worth it. I'm currently getting about 42MPG according to the consumption display. More pics are located here.
The main reason is that turbines don't rev like normal engines do. They're designed to be kept at a constant speed for long amounts of time.
They also accelerate to a higher speed slower, as well as decelerate slower (an innate characteristic of turbines)
Recent advances of CVT's (continously variable transmissions) can help ease the inherent problem with turbines, but its hardly worth taking time and research away from the hybrid and fuel cell cars, which are truly the future of automobiles (electric motors are vastly more efficient and powerful than combustions), to go back to something that was tried and failed already.

The new hybrid Civic is like a 4-door Insight. I believe the main difference in the drivetrain is that it uses a 4 cylinder motor instead of a 3. It has a CVT transmission, and I assume a manual too. You can read more about it at www.evworld.com.
"Hydrogen can neither be mined nor found through exploration.": Wrong.
Recently NASA discovered that large concentrations of hydrogen gas exist in the earth's rocky crust (as much as several hundred pounds of hydrogen in a cubic meter of rock). It can be mined, and as NASA has proven HAS been found through exploration. Mind you, not the same variety as "Lets blow a hole in the ground and see what comes up", but still far more available than previously believed. Essentially left over gasses from the formation of the solar system.
Mining can still be environmentally damaging if not inefficient, but still can be much more economical than existing means of hydrogen extraction.
Just because you can mod me down, doesn't mean you're right. Shoes for industry!

There's a good amount of information available about clean vehicles at:Well, with the 350 N-m/258 lb.-ft. @ 0-400 rpm of torque available from my Prius' electric motors from a stop, there isn't a car that can pass me from a standing stop (say, a red light) unless I let it...
A common adage is horsepower sells cars, but torque wins races...
