    Show this to be true.
    Compare the enegry used to overcome friction over a 20-mile struch of road comapred to the energy used to climb a 3% grade for that same 20 miles.
    Also, compare the energy used to overcome friction over 1/2 mile to the energy used to accelerate from a stop to 60MPH over that same 1/2 mile.
    In both cases, assume a 80,000 gross and 18 standard tires.

    You don't need to replace the wheels; you manufacture the truck in the first place with those wheels
    Yes... altnough this adds to the price of a new truck.
    It also doesnt account for all of the existing trucks.

    One new wheel and tire will cost less than two old ones as soon as the volume is pushed up by artificial means.
    As you are happy to confim - if there were an overall a cost benefit to these, they's be more widespread.
    Your idea forces compamies to spend money thay they won't bet back for the tunnel-vision goal of reducing fuel use.

    Re: CAFE standards for big rigs.

    I read an interesting article that helps delineate the anti-energy/efficiency position common to many on the far right:

    "with few exceptions, today's Republican mind seems to be stuck in Dick Cheney's basement, where if you don't toe the pro-fossils, pro-consumption line you're liable to get shot in the face. Really, the free market of lobbying has spoken: the flow of campaign riches from fossil fuels to Republican officials is three times that given to Democrats.

    Since the mid terms, the Republican stand seems to be that more oil is better and damn the climate and all the fuss about spills. And to heck with asthma and other chronic ailments directly linked to automotive pollution -- which along with coal use is bloating our nation's health care costs by hundreds of billions per year according to two well-funded studies (see here and here). And those costs pour directly over to our deficits."

    "The military's need for renewable power is clear -- it's to push back on oil dependency for distant bases where transporting oil is a distinct killer of troops. Such oil costs from $20 to $1000 per gallon and comprises between 30-80 percent of every convoy's load.

    On another economic note, thanks to Republican disdain for investing in renewable and efficient technologies through consistent policy such as a national renewable energy standard, or a ten or twenty-year production tax credit, US competitiveness is losing out. Governments of Europe, Asia and Latin America have supported this sector and are now exporting their goods and expertise into the States."

    Thank you for your non-topic-related point, enthusiastically supported with raw, partisan bigotry.

    When you can tell us how you -specifically- plan to triple the MPG of an 80,000lb vehicle, please feel free to do so.

    Here's some more info on the human power hybrid:



    "The Hungarian manufacturers of this three-seater believe there is a market for a vehicle that requires human input along with the more conventional form of propulsion.

    Pedals allow the driver and passengers to help the hybrid system, which consists of lithium-ion batteries that power four electric hub motors and a multi-fuel engine that can be used for long-distance trips. "[The pedals] make it possible to exercise while travelling," the company enthuses on its website, solo-duo.hu.

    To round out the alternative fuel sources, high-efficiency solar cells positioned on the roof collect, on average, enough energy to travel up to 25 kilometres at city speeds. The first production cars are scheduled to be on the road next year."

    The article is very to the point regarding the science denier thinking of many on the hard right, that we see examples of so frequently on this forum and from statements by the GOP presidential candidates, with the lone exception of Huntsman.

    Let's review that the regulations cited in the OP:

    "The regulations call for reductions on fuel consumption and greenhouse gas emissions by 2018 of 9 to 23 percent, depending on the type of vehicle. Trucks and other heavy vehicles make up only 4 percent of the domestic vehicle fleet, but given the distance they travel, the time they spend idling and their low fuel efficiency, they end up consuming about 20% of all vehicle fuel, according to the Union of Concerned Scientists.

    Experts say that a 20 percent reduction in heavy vehicle emissions would boost fuel efficiency to an average of 8 miles per gallon from 6 miles now."


    And increase of 2 mpg is hardly tripling the mpg now is it? Tell us again how it would impossible to increase the fleet mileage by 2 mpg over the next 7 years.

    Whcih is off-topic.
    While I understand that you are virtually always forced to offer bigoted, partisan red herrings, that doesn't change the fact that they are bigoted, partisan red herrings

    And increase of 2 mpg is hardly tripling the mpg now is it?
    No... but raising it by the 10MPG you offered, is:

    The views that I spoke to are well documented in this thread.

    I never said that and you are off topic. The regulation says 2 mpg over 7 years. Do you consider this technically feasible or not?

    Yes. Alost all of which are off-topic bigoted partisan red herrings.

    I never said that and you are off topic.
    This is a lie -- I provided the quote and a link to same where you said exactly that.

    The regulation says 2 mpg over 7 years.
    YOU said +10MPG, tripling the current 5.
    Can you or can you not tell us how you -specifically- plan to triple the MPG of an 80,000lb vehicle?

    If you had read the link in which the post with that statement ( a quote from the link). You would have realized the 10 mpg increase is not for class 5 trucks but an overall vehicle increase for cars, light duty trucks and up
    The new law tightens Corporate Average Fuel Economy (CAFE) standards that regulate the average fuel economy in the vehicles produced by each major automaker. The current CAFE standard for cars, set in 1984, requires manufacturers to achieve an average of 27.5 miles per gallon, while a second CAFE standard requires an average of 22.2 miles per gallon for light trucks such as minivans, sport utility vehicles, and pickups. The new rules require that these standards be increased such that, by 2020, the new cars and light trucks sold each year deliver a combined fleet average of 35 miles per gallon.

    Raising fuel economy by 10 miles per gallon nationwide will deliver real benefits. The Union of Concerned Scientists, for example, estimates that it will save 1.1 million barrels of oil per day in 2020--about half of what the United States imports from the Persian Gulf

    Bull****!

    Your strawman is of no interest since the regulation only requires a 2 mpg increase over 7 years. It is was the point of the OP. Go back and check if you do not believe me.

    And you didn't answer my direct question regarding the OP, do you consider this technically feasible or not?
