The details are a bit scanty, but this does sound interesting. Rather than having batteries, future laptops could be powered by miniature gas turbines. The inventor claims that a laptop could run for 15 to 20 hours on one of these things, which makes current batteries look very poor indeed. Of course, the article doesn’t mention how the devices would be fuelled. Given the safety concerns about batteries, I can see fuel burning engines causing even more alarm.
Cool idea though.
 You know, those things that explode all over the place
