  • We need to stop seeing governors and senators and representatives and saying, “they would be a great president!”

    Instead we need to see teachers, co-workers, and neighbors and say, “they would be a great on the city council or county government or as a state representative.”

    We need to stop thinking in terms of only one chance of victory every four years and start putting people who care about us in places where they can help.

    Of course, that means we have to be prepared to run, and that is hard as hell. So many of us are stretched to the absolute limit just trying to survive. I honestly don’t understand how anyone can do it.

















  • You are correct. It relates to the torque (rotational force) that can be produced at different RPM.

    Diesel engines have a narrow range of RPM where the torque is highest. At low RPM, the torque of a diesel engine is low. That’s why trucks have to shift into a low gear to start moving and shift multiple times to get up to speed. The driver uses the different gears to keep the engine running within the optimal range of RPM.

    Electric motors have high torque at low RPM, so they can start a heavy load moving without having to have any complicated gearbox between the motors and drive wheels.

    In a diesel-electric locomotive, the diesel generator can be designed to run at an efficient speed without being affected by the mass of the train. The electricity it generates powers the electric motors which have the necessary torque to handle moving the train.
