    Thank you, Captain Obvious. :wink:
    I believe there is room for occasional pun-based humor.


    Here's an old EVcast interview from November of last year:

    Wind car update.
    Zero Carbonista's wind-powered car with no name keeps moving forward

    I'll be interested to see if they're ever able to achieve those specs.


    An embeddable youtube version of the video isn't yet available. But watching it, it appears each wheel has an independent controller.

    This part 7 went up on Youtube a couple days ago.

    They never bother to talk about the technical aspects of this project, but the videos show a bit. I took some quick screen caps of this latest one.

    Each motor has it's own liquid cooled controller box.

    I wonder if that's where they really plan to mount the controllers. That side hose likely runs to the radiator up front.

    Those white PVC test boxes appear to contain industrial off-the-shelf electrical components.

    Looks like for the purpose of this test, each motor (and thus each rear wheel) has it's own hand held controller.

    I'm still interested in what approach they plan to use to address the relative wheel speed issue since they don't have a mechanical differential.

    But they do have two separate motors and two separate controllers. They can just ignore that relative speed issue, inner motor would work a little bit harder, outer a little bit easier.

    Yeah, Dale Vince typically either pretends Tesla doesn't exist, or tries to take a dig at them.

    You're probably right, but it depends on how their controlling them. I don't know the details of those UQM controllers, but they likely control for frequency (speed). And then things are a little complicated to balance the two.
    Actually, if the controllers are able to (ahem) control for torque (and they should be), then they should just be able to set the torque for both wheels to be equal. Then you have the equivalent of an open differential. By setting a limit of the maximum difference in wheel speed, you should be able to simulate a limited slip. Again, they don't bother to discuss these details.

    We been following them so we know there is more to the project than just making and electric Elise (like Zytec and Detroit Electric (and probably Lotus someday)) but that video showed nothing significant in specs or design that would make it particularly different from a Tesla (like that wacky bodywork we saw a few months ago).

    I do [plan on putting a wind turbine (3 to 5KW) someday. Will that put a stop to Dale's folley?
    :smile:
    I kid. If Tesla did not exist I would be absolutely thrilled at what he is doing so I wish him well as competition is healthy.
