Electric Motorcycle Inventor Crashes at Wired Conference 337

not5150 writes "The inventor of the electric 'KillaCycle" motorcycle was taken to the hospital for x-rays after demonstrating the vehicle to reporters. Bill Dube, a government scientist during the day and bike builder at night, attempted a burnout in front of the Los Angeles Convention Center during the Wired NextFest fair. Fueled by the "most powerful" lithium-ion batteries in the world, the bike accelerated uncontrollably into another car. There's a video interview (thankfully before the crash) and footage of Dube crashing."

    sure as hell emphasizes the difference between an inventor, scientist and engineer...

    ..and a professional stunt man who will ensure adequate clearance zones, safety margins, appropriate safety gear and at least apply a basic safety audit before carrying out a start stop on such a potentially powerful bike.

    ..that would be my number one fantasy vehicle from a movie. (or maybe a land speeder :-).

    And the eye candy who was hired to sit on the bike was quite nice. Sorry that's amazingly un-PC of me and I apologize. :-(

    By making the vehicle seem dangerous, it instantly becomes desirable to a great many idiots who will quickly become enthusiasts.

    This will depend on your definition of "easy"... if it means "in less than five passive components", then you may be right.

    Anyway, you mentioned the railway engine's AC-DC-AC drive. Now, to run on DC, just skip the first rectifier: you can run the inverters directly on DC. In fact, many railroads do just that. There are lower-powered inverters and motors available for lighter-duty applications. Did you know your average "brushless DC" CPU fan is in effect an induction motor with an integrated drive?

    So, if you have a 500 V battery pack capable of 10 A, just slap a 5 kW drive with a suitable control input and a 5 kW induction motor on it and you're basically done. (Select ratings to suit application and products.) Ask your supplier for more information.

    "I wasn't wearing a helment, because..."

    There's nothing you can say here that will justify not wearing a helmet.

    I recently put a new seat on my Ducati. I wanted to test it, but I was only taking to the end of my street and back. As I left the driveway, I hit an acorn (yes a fucking acorn) that had been smashed, lost the front, and went down. Low speed, no problems, but I banged my head pretty hard, hard enough to send me to the hospital.

    That is, if I had been dumb enough to listen to the inner voice that said "I don't need to wear a helmet because...". Luckily, I'm not that dumb and I did wear my helmet, so I got up and walked away.

    I'm not in the insurance game, but I've heard myths that insurance rates are higher because of people who wear helmets. A $5,000 funeral is a hell of a lot cheaper than a $50,000 hospital bill from the same accident. Don't know how true that is...

    Thanks, I forgot to specify the type of combustion engine. However Wankel/rotary style engines still only operate up to 2 or 3 times the RPM of a reciprocating piston engine, whereas an electric motor in the same context spins an order of magnitude faster quite easily.

    Point being, you *still* need gears using a rotary engine in a car, so both points still stand 100%.
