New X-Prize for Fuel Efficient Cars Announced 371

Posted by Zonk from the it's-like-the-robot-one-but-with-less-programming dept.
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.'"

      Sure, it's less exciting on a sci-fi-this-is-awesome level, but it seems to me like the most practical of the X prizes. This is the first that could very conceivably have a massive effect on worldwide transportation and even politics and the global economy in the next decade. What other x prize is tied so closely to the major environmental concerns of the day?

      Maybe fewer people will follow the prize closely, but I suspect that more will follow its aftermath.

          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).

Assuming linear acceleration from zero to sixty (which is probably an optimistic assumption), say you get on the highway on-ramp at 30, and have to accelerate up to 60 to merge. You'd need 6 seconds to do that. How far would you travel in those 6 seconds?

    Well conservation of energy for one. The energy required to split water in to hydrogen and oxygen is greater than the energy you get from burning it otherwise we'd all have perpetual motion machines running in our back yard.

    Flow rate.
    Say an engine has a displacement of 3 liters and is operating at 2000 rpm.
    3 liters * 2000 rpm /2 (as this is a 4 stroke engine) * .85 (assume this is not turbo charged so the cylinder is never completely full) = 2550 liters of air per min.

    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

  • I wonder, must the winner meet recognized safety standards to win the prize? It's considerably easier to design a vehicle that won't ever come close to government crash standards and thus couldn't possibly be licensed as a car... If the winner builds a glorified ultralight autorickshaw that would probably kill all occupants in case of a low-speed collision with a Pinto, some kind of 3-wheel motorcycle with a full fairing or some other contraption that is "unsafe at any speed", then I see little point to thi

    I don't get it....wouldn't the market dictate progress for massive fuel efficiency gains? Do you think if people were honest-to-goodness clamoring for 200mpg alternative vehicles, the companies would already be doing it? I would think there's a much greater reward than $10M that the market would provide. You don't think that if GM or Ford or Honda or Toyota or Joe Garage inventor could come up with a *normal* vehicle that fit cars, trucks, and SUVs, and make it get 100+ mpg, all for a competitive cost (ie, same as or less than our cars are now) that they wouldn't?

    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.
