Engine On a Chip May Beat the Battery

Krishna Dagli writes, "MIT researchers are putting a tiny gas-turbine engine inside a silicon chip about the size of a quarter. The resulting device could run 10 times longer than a battery of the same weight, powering laptops, cell phones, radios, and other electronic devices." From the article: "All the parts work. We're now trying to get them all to work on the same day on the same lab bench." The goal is to do that by the end of the year.

    Turbine blades, made of low-defect, high-strength microfabricated materials, spin at 20,000 revolutions per second -- 100 times faster than those in jet engines.


    And you thought a hot battery in your lap was scary.

      Lasers and turbines on chips? I think this is an elaborate plan to make deadly military level pc components. With the detection of non-drm'd media, the chip will eject, fly close to you and shoot you in the face. It's the next level after "Trusted Computing", "Feared Computing".

  3. Hot exhaust? by Bryansix · · Score: 4, Funny

    The article doesn't mention what happens to the hot exhaust after it passes through the turbine. Does this mean that have not tackled this problem yet? This could give a whole new meaning to the whole "laptop frying your balls".

      what happens when it runs out of gas?

      I'm going to go way out on a limb here and speculate that when it runs out of gas, the engine stops turning.

    Miniature fighter jets with lasers all etched out of a silicon crystal.

    We could drop half a billion of them over the middle east.

    Because as we move to hybrid gas-electric vehicles, more and more mechanics are finding they need a degree in electronics just to be able to fix your car. So to level the playing field, we felt that electronics geeks should have to learn how to fix an engine too.

    will they be putting tiny engines inside silicon*e* ? Just imagine, breasts that swing *themselves* even when the woman is standing still. It truly would be Utopia. Or Stepford. I always get those two confused.

    I would be more interested in a bioelectric power source, like electric eel cells fed with sucrose.

    Electric eel generator, bird beak phonograph needle and dinosaur garbage disposal are already patented by Fred Flintstone.
