  1. Longer than getting to the moon? on Obama's Impending NASA Decisions · · Score: 1

    I know the time frame has been on here a lot, but why will it take 6 years to get a new operational version of the shuttle? It took less than 7 years from JFK's challenge to get a man on the moon, so why can't we get Americans in space any faster?

  2. Re:Fuel economy on Fuel Efficiency and Slow Driving? · · Score: 1

    Most cars make their best fuel economy somewhere between 1800 to 2200 rpm.

    Umm, isn't fuel mileage completely dependent on the RPMs your car is turning? What I mean is that at higher RPM (revolutions per minute), the valves are turning more than at a lower RPM. Each turn uses the same amount of gas, so a higher RPM means you are using more gas than a lower RPM.

    While I appreciate your test, your basics are wrong.

    One of the easiest ways to change your fuel mileage is to watch your tachometer. If you floor the gas, that needle goes up and you use more gas than when you accelerate slowly. Same goes for the interstate- watch that needle and see where it is the lowest for the speed with which you want to get home.
