    Good for him. Do you mean it went the 200 miles on the charge? It is more tan 200 miles from Oregon to San Diego.

    First, what a terrible name for a car and a insult to the genius that is Nicola Tesla.

    Who happens to be one of my favorite historical people.

    While I was in grade school having Eddison shoved down my throat my Dad bought me a science book that talked about a guy named Nicola Tesla and his inventions.

    My Dad worked for NASA as a Aeronautical engineer and helped me to understand the true genius that was Tesla and why we would should be celebrating him and
    not Eddison.

    First, Eddison focused solely on DC power and he was going to build DC powered Grid.

    A highly inefficient grid that would have to be comprised of massive 6" diameter conductors and substations a mile apart to boost power.

    Tesla invented AC induction and patented the AC induction motor AND the Induction transformer.

    Which our Grids use today.

    Thanks to Tesla , who was ROBBED we could run small diameter high tension cables for miles and miles and step it down at first the Sub Stations miles away and then at the buildings or homes for useful power.

    So why is this DC powered car named after the inventor of whats essentially AC induction ?

    Plus the technology behind the Tesla is not that difficult to understand.

    Hmmm..lets see.

    Thousands of Nicad powered batteries in a series parallel configuration that are fed into whats essentially a stepper motor controller that takes that DC and chops it up and outputs it into modulated square waves that are used to vary the frequency on the drive motors which are just large electronically commutated stepper motors.

    I think it is a defensive move. GM especially has a history of anti-competitive behavior when it comes to new tech and since Tesla is under constant attack by the mainstream car companies and political sphere, then by releasing it to everyone, the chance is that the tech wont get locked away in some GM vault rotting away like so much other tech before them. It reminds me a bit like what Ralf Nader did to the collapsible steering column...expose the car companies by shaming them in public.. here Musk is making sure that the same car companies wont shut him up regardless on how much they try.

    I just hope it doesn't come back to bite them later, business wise. Giving technology to a competitor makes them better able to compete. I really like this company and hope it sticks around.

    How many problems do you think you would have with a Street versión with no dealers around to fix it?
    Their issues with the Roadster were scripted.

    They were sued for it.

    You don't need a dealership to fix them. There are hardly any moving parts to begin with, but those that are there are nothing that can't be serviced by any auto shop and only thing that requires any sort of "regular" maintenance are the brake pads and tires, both of which can be done anywhere.

    The hell there isn't.

    Thousands of nicad batteries in series parallel configuration input into a Pulse width modulation controller that out puts modulated square wave to the electronically comutated motor. The PWM is how they vary the speed of the motor and then the speed of the car.

    That may sound simple, but there are tons of electronic components in that car to make it " feasible " ( no electric car is feasible ).

    And there's nothing green about that car either. From the manufacture of the ni-cad batteries and their disposal to the all of the election boards, components and MASSIVE capacitor bank thats in that inverter there is more toxic about that car than a comparable internal combustion engine.

    It a product of a ideological push that is more about symbolism than practicality.

    I troubleshooted and repaired large inverters for industrial applications for years when I was younger and they had a habit of detonating when they lost their ability to output a single phase of PWM. Their coke can sized high voltage capacitors would then overcharge and blow the cover right off the inverter.

    They're very expensive, as is the not green battery pak in that vehicle and have to be disposed of like their toxic waste.

    If it makes you feel any better, just pretend Musk named it that after the unit of magnetism instead of the guy. (although I do realize the unit is also named after the guy). It may soften the blow.
    Maybe you should ask Alessandro Volta's descendents what they think of the Chevy Volt.
