    Yeah, and the only two wheeler you'll get is a stationary exercise bicycle with a dynamo to power your virtual reality system with option A) you riding an Electra Glide into the sunset of Monument Valley or, B) you riding on an ADV on the Alcan in deep mud chasing grizzlies.

    And where are the tents where the car owners can stay until their car's battery is charged?

    I saw some figures it takes hours to charge an electric car battery after a 50 miles trip.

    Let's take an electric car motor with 20 kW (~26 hp) for half an hour trip to the office that needs 10 kWh to charge the battery or, 1,250 Watts over 8 hours. Looking at some of the panels available today you would need a ~100 sqft panel to do that charging in 8 hours (at perfect sunlight).

    Or roughly 6 panel insets shown on the Dell picture. So one of the large "roof" panels would charge 10 cars. As many as would fit under that "roof". All using a moderate size motor and perfect daylight.

    Sounds technically feasible (if I haven't made one of these stupid calculation errors/assumptions). Might even work well where Dell's HQ is.

    The winners were Team Agni, a couple of privateers from the UK and India. Their patented "pancake" motor will be available on (rather expensive) production bikes next year.

    Electric vehicles are "remote emission" vehicles not non emission. As pointed pointed out above the electicity to charge them comes from somewhere and then you have the whole battery production and disposal issue. Many do not seem to look at the entire picture. Another example would be the CFL lamps, they contain mercury and to make them acceptable to consumers the price had to come down so many of the cheaper models are built with tranformers that disrupt the power curve. If another lamp type is not developed or more efficient transformers are not used the power suppliers will be required to spend millions to correct the power quality issues. Guess who will pay for that.

    In a recent Popular Mechanics article they stated that the automobile (motorcycle) consumption of petro fuel is about 1% when compared to other consumers. The highest levels of consumption are by electoplants and oil used in home heating/industry heating. Here in PA. we are sitting on huge supplies on natural gas that the powers to be are "paying" gas companies to "stop finding"!

    At this point I'm not willing to fly in any plane that operates on anything other than aviation fuel and I will continue to heat my home with clean natural gas and ride my RT to and from the office.

    It appears to me that often the most "green" are often the highest consumers!
