Not so hot on the heels of the Philips L-Prize bulb comes this funky piece of hardware from General Electric, which knows a thing (or two) about electricity. It's a 27 watt LED bulb that produces as much (or more) light as a 100 watt incandescent bulb, and the coolest feature is how it keeps itself, uh, cool: silent puffs of high-velocity air.

Compared to other, more modern storage mediums, optical discs are terrible. They're big, they're fragile, and they're hard to access. You may not agree, and neither does GE: they've just developed a commercial micro-holographic storage technology that can fit 500 gigs on an optical disc.

Now this is neat. GE's Visible You is similar to Microsoft's Kinect, but instead of letting you play video games with your body, it acts as a living X-ray.
