miowpurr writes "A new X-Prize for ultra fuel efficient cars has been announced. The winning car must 'carry four or more passengers and have climate control, an audio system and 10 cubic feet of cargo space. They also must have four or more wheels, hit 60 miles per hour in less than 12 seconds and have a minimum top speed of 100 miles per hour and a range of 200 miles. Those that qualify will race their vehicles in cross-country races in 2009 and 2010 that will combine speed, distance, urban driving and overall performance.'"

Technology: Early Contenders for the Automotive X-Prize 309 comments
longacre writes "With the official entry period for the $10 million Automotive X-Prize contest just around the corner, Popular Mechanics offers a preview of the most promising entries. Among the 100-mpg vehicles that Detroit (and Japan) have claimed impossible to build comes a hybrid designed by a class of inner-city high school students in West Philadelphia. Also displayed is a futuristic-looking electric model with a range of 300 miles. We discussed the beginning of this contest earlier this year."

I don't think there is much likelihood that this prize will have any major impact on an environmental level. Addressing fuel economy globally is not at all about creating the most efficient technology. It will be about creating the most mass producible solution. The best solution will be the one that relies on the most abundant resources.

Doesn't the Tesla run on something like 100 laptop batteries. That means that for each one, 100 fewer laptops can be produced.
It's impossible to manufacture more batteries?
One factory produces seemless containment units for nuclear reactors. They produce 8 a year. That means that only 8 reactors based on that technology can be opened each year.
Yes but if we also build two seamless containment unit factories per year, we can build 24 reactors the next year, 40 reactors the year after that, and 56 reactors the year after that. Sorry, this is one game of Starcraft that you're gonna lose playing that way.

You could make the engine part a trailer [dansdata.com]. When you're doing your inter-city commutes, you'd just plug it in at work, plut it in at home, and go about your merry little business as a fully electric car.
When you want to go cross-country, you'd hook up the trailer to the car, and as necessary, it starts up, generates power for the battery, and shuts down, like hybrid cars. Except unlike hybrids, you're not carrying the whole engine and supporting systems (gas, cooling, exhaust, etc) with you everywhere you go. And like hybrids, it can work the engine where its most efficient. (The ICE is so inefficient, that it's way more efficient to use its mechanical power to generate electricity, and then use the electricity to move a vehicle - see the popular diesel-electic train).
Heck, if there's a standard for wiring up these trailers and cars together, a whole new industry is born - car companies can produce an all electric car and their standard trailer, and third parties can make their own trailers. Or rent a trailer if they don't go on long trips frequently enough to justify owning one (aren't most cars just used for the daily commute? In which case the plug in at office/home would work just fine).

Flow rate.
Say an engine has a displacement of 3 liters and is operating at 2000 rpm.
3 liters * 2000 rpm
the electric power required to electrolyze the hydrogen equivalent to 1 gallon of gasoline is equal to (500 moles) x (0.06587 kWh/mole) = 32.935 kWh, and the approximate cost of that power = (32.935 kWh)

How much current can you alternator put out? Maybe 100 amps. How much hydrogen could your car generate per min? How much power can your alternator produce 100A *13.7V 1.37 KW
How much hydrogen could your car produce per min?
1.37 * (.06587 kWh/mole) / 60min/hr * 22.4 liters/mol = 0.033 liters of hydrogen per min
Compare this to the number above for the volume of air entering the engine.
How much hydrogen would one need to run a vehicle?
If 500 mol of hydrogen = 1 gallon of gasoline
If the vehicle gets 30 mpg at 60 mph = 2 gallons of gasoline per hr or 1000 mol of hydrogen per hr * 22.4 liters / mol / 60 min / hr = 373 lites per min of hydrogen
Compare this to the number above.
If anything all those hydrogen generator scams are going to do is create a vacuum leak that will turn on your check engine light.

The truth is, as much as the idealists would like to think otherwise, price and value are running the show. Fuel efficiency is an added bonus, and as gas gets more expensive this will only increase. Although, I honestly don't see it REALLY making a difference until gas gets $20+/gallon, maybe more. Think about it - it sucks paying $3 a gallon, but we do it because we have to. If it jumped to $5, it would suck even more, but we'd still pay it because hey, most people gotta get to work somehow and that's the only option. Rising gas prices crimp our lifestyles that we've chosen, but at what actual price point does the price of gas and the cost of driving actually truly outweigh the need for your chosen employment? For the majority of people? The automakers, all of them, are only giving the people what they want.
Back on topic, I don't really see this as anything more than a novelty, and a stupid one at that. How much would GM make if tomorrow they released say an Impala priced at the same it is today, but with 200mpg, and where you don't have to change your driving habits or make any radical fueling style changes. You can "fill" it up the same places you can now; i.e., it's not more work for you the consumer. Wouldn't that be worth a heck of a lot more than $10M? You don't think they're already thinking about this?
The point is people want fuel economy and savings, but they don't want to drastically change their lifestyles, rightfully so. I want the insanely high Miles Per Fillup. But I want to pay a comparable price to what today's average "normal" car sells for...a $5-10k premium is too much. I want the ease of being able to refuel it anywhere - I don't want to have to come back to my home base, or only be able to go to certain filling stations. And I want this in any vehicle I choose - be it car, truck, van, SUV, motorcycle, etc. Why does fuel efficiency have to equal econobox? Why can't I have a 200mpg Hummer? This isn't rocket science, and this "prize" isn't going to push the revolution any faster.

Well, Germany springs to mind, Ohio during the day (was it Ohio that has unrestricted speed limits during the day - or have they revoked that rule already!).
Is it safe? The Government, well ours in the UK anyway, have been doing a great job trying to make people think that speed is somehow inherently dangerous. Heads up folks ... it isn't!
On a (reasonably) clear motorway in good weather in a well maintained car and 100MPH is actually fine. On the other side of the coin, 20MPH outside a junior school at chucking out time may well be the posted speed limit but could be way to fast! This is the basic reason why most people have no respect for the law when it comes to speed limits - 99.9% of the time the posted limit isn't appropriate, and yet they try and enforce the limits 100% of the time - exactly who are you protecting by giving a ticket to someone passing a school (often now a 20 limit in the UK) at 25 or 30 MPH at midnight? It's farcical!
We've had variable speed limits on the M25 for years now ... why not have a 15MPH limit by schools when it's the times that the kids arrive and leave school (in mummy's humvee usually!), 20MPH for the rest of a normal school day, + 1hr either side of school time, and 30MPH (or whatever is the prevailing limit in the area) the rest of the time?

KE = 1/2*M*V*V: kinetic energy rises as the square of the speed. Claiming that speed isn't inherently dangerous is like claiming jumping off buildings isn't inherently dangerous. While it might be possible, though skill and safety equipment, to minimize that danger, it still clearly rises with speed.
Add to that, that while well-trained drivers with excellent reflexes might be capable of driving at high speeds safely, many inexperienced drivers with below-average skills or reflexes cannot, and they may not be aware that they cannot. Most people think they're excellent drivers, even people who clearly aren't.
I'd love to see driver tests done like pilot tests: every two years (or more often for professional drivers) complete retest, and loss of driving privileges until the driver takes classes and passes the retest.

As for the top speed, that's what you'd get to after holding down the accelerator on a flat, straight stretch of the road for 2-3 minutes. Reasonable traveling speed for a vehicle is always some amount below the maximum speed of that vehicle.
