Planet CNET Episode 23: Lasers on a Volvo

Join CNET Australia's Ella Morton from the premiere of Baz Luhrman's wartime epic Australia for the 23rd episode of our global tech show. This week, our very own Rory Reid is in Scotland to drive a car with laser beams mounted on the front.

No, he hasn't been recruited by MI6, it's a safety feature on the new Volvo XC60. A beam behind the rear-view mirror detects objects in front of the car and makes it brake itself, in case you fall asleep at the wheel.

Meanwhile, Kara Tsuboi goes on-set at the Discovery Channel's new series Prototype This. They build a new protype every week, with a crack team of geeks making everything from fighting robots to waterslide simulators. Kind of like a nerdy A-Team. Finally, Germany's Daniel Schraeder shows us the very latest in techy cleaning -- robot wacuum vacuum cleaners.
