Engine On a Chip May Beat the Battery

Posted by ryuzaki0 on from the is-that-a-quarter-in-your-pocket? dept.

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.

    So what are the consequences for the environment here? I realise that it's not nice to have billions of batteries lying around, but do these mini-furnaces cause any other kind of pollution? I did not find anything about this in the 'challenges ahead' section, nor do I know much about gas (no pun intended) to be honest.
