    I read where the use of only Lead-Acid rechargeable batteries were allowed. I laughed, as I thought of someone (me?) employing LIPo cells and would hardly if at all, not even need charging, toss the solar cell mid race and your gone. I do hope that there is a minimum weight requirement and that the team with the most $$$ is not the foreseen winner.
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    Sometimes we witness a strange dose of what could be perceived as some sort of short term phenomena where Pin approaches Pout. Read on ..........

    I saw a solar powered motorcycle once. These two engineers who were already tuned in to the alternate energy scene, lets say "lifestyle" for now. Our company made fuel cells of many types. So one day Armondo & Harry, two of the most enterprising engineers in the company, had taken lunch together riding said motorcycle when on the way back the old (and just recently revived mind you) motorcycle's motor seemed to quit running halfway through the intersection, just in front out company's parking lot. So as I watched the two of them riding the now very streamlined and silent motorcycle Armondo being the team mate that he was, jumped off the back of the motorcycle and pushed it with Harry still proudly sitting in the command position, up the curb, across the grass and into the parking slot they left from.

    ....So how was it Solar powered you ask? That was Armondo's last name; "Solar"................................................... What?

    73 and the best of luck and sunny skies with a tailwind from all us out of gas hot rodders here in Texas-

    Only thing I see wrong with the design is using the trailer tires. Spoked motorcycle wheels and street tires with a solid center rib would likely have less weight and rolling resistance.

    If that car ain't got some heating, that will be one very cool ride this time of year! Good luck, and We hope it makes it all the way..

    We are aware of that issue, due to the base design coming from a golf car, the solution was to order special bias ply trailer tires rated at 90 psi ... air resistance is our concern though the design did not allow for any fairings.. Rolling resistance looks to by quite minimal as the footprint is about 10 - 12 mm wide.

    There is air conditioning on board if too hot i.e. one big high velocity fan LOL. We are hoping for cool air/ easier driving and better for the panels and electronics as they run very hot any way.

    We have many Antennas...GPS, Telemetry, and our handi talkies. At the time of the picture the Telemetry was in process and Connor has studying for his ticket.

    BTW. Cost is an issue, always will be, that plus the time involved, I feel, scare so many people away from programs like this.
    It is great to see programs like FIRST robotics be so successful or NASA rocket launch or their Human Exploration Rover Challenge ( which we came from). We are proud to say we are the only High School in Illinois to do this but at the same time we also realize many students are not getting this opportunity, which is sad. The fact that these Student Engineers voted to take on this project in mid year and will transport a car to scrutineering that has a good chance to pass and qualify, made them winners.
