Question of the day: Engine with the highest power/weight ratio?

Who makes the engine (ie an engine with an output shaft that you could use to drive a pump or something...) with the highest power/weight ratio, and what is that engine used for?

    It is a ‘Wankel’ made by "Moller International’ in Davis, California. It is sold for other uses, but it was developed for the ‘Sky Car’. They have tours on Thursday afternoons. (make a reservation). The tour is great fun.

  2. Darron says:

    According to Epson, it’s their miniature flying robot’s ‘acoustic’ motor.

  3. Scot Boyd says:

    I’m going to guess it’s the drive motor in an ultra-small hard drive.

  4. George, Darren, Scot:

    No, no, and no.

    This guy claims the Zanzottera MZ202 has the highest power-to-weight ratio "on the market today."

    How about a nono motor – those little devils are tiny so can’t weigh that much 🙂

  7. I have no idea what the right answer is, but Eric asked for an *engine* not a *motor* in his question. Maybe he was trying to give a hint.

    There’s a tradition that things called "motors" are powered by electricity, and those things called "engines" are internal combustion devices. There’s no strict rule about this, of course.

  8. Tommy is right. It isn’t an electrical motor.

    There’s another hint in the post.
