Engine on a chip promises to best the battery

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 can, powering laptops, cell phones, radios and other electronic devices.

The MIT team has now used this process to make all the components needed for their engine, and each part works. Inside a tiny combustion chamber, fuel and air quickly mix and burn at the melting point of steel. 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.


No doubt MIT likes how this quote reflects on MIT:

For all the difficulties, Epstein said the project is “an astonishing amount of fun” — and MIT is the ideal place for it. “Within 300 feet of my office, I could find the world’s experts on each of the technologies needed to make the complete system,” he said.

That quality (high concentration of leading experts) also explains why world class research universities are so important to innovation, scientific breakthroughs and economic gains.

    Wow, let’s get that engine-on-a-chip technology going and make it available to the general population soon! I’m tired of my laptop running out of juice at the most crucial times — and I’m sure many other people are as well.

    “Within 300 feet of my office, I could find the world”™s experts on each of the technologies needed to make the complete system.”Now that is a fantastic quote!!!

    Instead of irradiating the environment with electromagnetic waves, a power transmitter would fill the space around it with a “non-radiative” electromagnetic field. Energy would only be picked up by gadgets specially designed to “resonate” with the field….

    I’m not sure at what point of development the recent battery’s are but in almost any industry it is the most reliable form of backup power and power. It’s kind of downbringing to never hear about these sort of projects anymore. You would almost start to think that it was downplayed or not picked up by the industry on purpose.
