Bridgelux silicon LED could mean bright future for solid state lighting

While Democrats and Republicans squabble over the future of the incandescent light bulb, a Livermore-based company has produced an LED that they claim could lead to brighter, more affordable solid state lighting. By growing gallium nitride on low-cost silicon wafers, as opposed to the typical sapphire and silicon carbide substrates, the company has achieved an output of 135lm/W (lumens per watt) with a color correlated temperature of 4730K-- brighter than any affordable LED lighting solution we've ever seen. Of course, this isn't the first time efficacy of this level has been achieved, and we've yet to see a practical application, but if Bridgelux's numbers are right, this could mean a 75 percent cut in LED production costs. The company expects the technology to make its way to real world lights in the next two to three years -- perhaps by then the furor over pigtail light bulbs will have settled a bit. Enlightening PR after the break.

RED EPIC shoots birds at 96fps, no dog needed to retrieve them (video)

Forgive us if we take a moment every now and again to relish in some resolution overload courtesy of a RED EPIC, but we just can't help ourselves. The video below (and picture above) come courtesy of Tom Lowe, who filmed a sequence of birds frolicking in the water at Salton Sea, California, captured at 5K resolution and at 96fps. This gives everything a rather majestic air to it -- though the soundtrack certainly doesn't hurt. Click "play" and enjoy, and then wish that your connection were fast enough to handle an uncompressed 5K video stream.

[Thanks, Tom]

Clement Valla's Postcards from Google Earth blend 3D with 2D, look freaky

The satellite imagery used in Google Earth is captured in 2D. The terrain that it covers is rendered in 3D. Sometimes those disparate layers don't line up, and sometimes those results can be quite compelling. Artist Clement Valla has collected some of the most striking examples in an online gallery called "Postcards from Google Earth, Bridges." It's 60 images from around the virtual globe, pictures that are occasionally janky, occasionally boring, but often quite moving in a Salvador Dali sort of way. Our favorite is above, but feel free to share yours in comments below.

Veritas RSIII Roadster Hybrid melds plug-in tech with 600HP

It isn't exactly the hottest hybrid we've ever seen, Porsche's ludicrous 918 RSR still takes that crown, but the Veritas RSIII Roadster Hybrid is certainly no wheezy commuter. It's a tiny, open-topped racer that features a 507HP V10 from BMW that's been paired with a 105kW motor to spin the front wheels. It's much the same arrangement of the Porsche, again relying on a KERS flywheel to generate electricity that's stored in a Li-ion battery pack, which can also be charged separately. The car can actually limp around for up to 31 miles powered by just that front motor, but when both sources of thrust are called upon the sled gets to 62MPH in 3.1 seconds, as fast as a 911 Turbo S, and it'll keep on going until the speedo hits 205 -- or the car hits something immovable. No word on price or availability, but there is a version with a roof coming this summer, and a fully-electric model due in 2013.
