A round-up of the latest technology news from around the globe.

PACK OF CARS: Hate driving round and round in parking buildings? In Budapest the Woehr Parksafe car parking system uses software controlling automated lifts and slides to pack 200 cars into a tiny space only 12 by 25 metres. 3D parking. See more here and a video on YouTube.

ONWARD AND UPWARD: Computer chips are flat so there's only so much you can fit on them. A new method of 'growing' wires to extend above the surface offers scope for a 3D chip with more power. 3D with everything. Details at NewScientist.

HONEY I'M HOME: The new Allure Mobile energy-saver thermostat tracks your iPhone When it detects you're on your way home it adjusts the temperature to your favourite setting. Can it get the dinner on too?

UNTRAINED PILOT: Spotter planes for Search and Rescue could use specialised algorithms, rather than a crew, to direct their search. An operator on the ground, who doesn't even need to know how to fly, controls the plane and can analyse photos to find missing people. Why do they need full-size planes? Details at NewScientist.

BREATHE EASY: Mechanical ventilators are usually huge and can cost $30,000. Students from MIT have devised a $100 mobile ventilator from readily available parts that could save lives in emergencies and
poorer communities. A nice application of the 80-20 rule. Read more at MIT.
