    My concept is the recharging post for electric cars and people.

    The post consists of solar panel, displays, wifi hub. recharging outlets for electric stuff and car. displays can used for advertisements, showing status of cars, etc. it provides people nearby it with internet connection viawifi. With display, we can get money for operating the post, and give useful information for car status including BIT results. The USB outlets enablepeople recharge their portable devices like smartphones, MP3 players, and so on. The total power is available with the power recharged via solar panel.

    Please give comments on this concept for brainstorming. Thanks.

    display, we can get money for

    operating the post, and give useful information for car status including
    BIT results.

    smartphones, MP3 players, and so on.

    Why is it so hard to do some simple math before spouting this stuff?

    A charging post must be FAST.
    How many cars do you want to charge in a day...including night?
    That sets how many car's worth of batteries you need.
    How many cloudy days do you want to survive?
    Multiply the number by that.
    How much does that cost?
    Not convinced?
    How many acres of solar panels will be required to provide
    adequate charge for your battery hoarde...while still charging cars?

    All the other stuff is completely irrelevant to someone wishing to
    charge their car.

    We have several grid-tied charging stations around the city.
    I've never seen ANY in use.

    Bottom line is that all electric cars and solar have no chance of
    success as long as there is any alternative lower cost source...oil.

    Sure, waive the green flag...invest a zillion dollars in technology.
    Show your friends how cool you are.
    It'll be useful some day, just not yet.

    An all electric car makes no sense unless you always drive between
    two places that have chargers (yes, both can be your home) and can
    be guaranteed of a vacant charger at each end. Takes only one other
    guy to ruin your plan. Nobody wants to be stuck for an hour at the
    drug store so they can get enough charge to get home. It just ain't
    practical.
     
  3. If you have enough juice for the round trip, then you only need a
    charger at home base, be that home or a workplace.

    The Nissan Leaf has a ~75 mile range, which is enough for most
    commuters (more than double the average round-trip commute).

    Pretty useless for any kind of distance transportation, though, since
    they didn't see fit to include a backup gasoline motor.

    Most working people would not find a solar charging post useful at
    home, since their car is not usually at home much during daylight
    hours.

    Guess it was too much trouble to read what you quoted. ;-(
