Fuelless Flight with Air Submarine?
An anonymous reader writes "Using the same physics principles as submarines, a new company is planning a fuelless air ship. Recent advances in ultra light and strong materials are making this concept a practical reality." There's no question that changes in buoyancy can be used to propel a vehicle, but "fuelless" is going to be tricky. -
Bringing CAD to Linux
Christopher Cashell writes "I've often heard it said that linux has the potential to be an ideal CAD platform, and the only thing holding it back is the lack of commercial quality CAD software (a la AutoCAD). Enter QCad, an easy to use 2D CAD project that began as a splitoff from CAM Expert. It was initially released with a 'free for non-commercial use' license, but this has recently been changed to the GPL. It's an excellent program, and earned 5 out of 5 Penguins on Tucow's Linuxberg review." CAD could/should be a "killer app" for Linux on the engineering desktop. I had a conversation a few months ago with an editor at Machine Design magazine about Linux - and how a good CAD app might set off a wholesale migration to Linux by design engineers.
