Long running batteries and trees as streetlights

Batteries last 10 times longer when fused with Virus


Apparently two wrongs can make a right (referencing the ever popular tobacco plant and mosaic virus that likes to dine on it).

Scientists have recently discovered that coating the rods of the mosaic virus with a conductive substance and then cramming them into lithium batteries causes them to last longer. How much longer? Ten times actually.

So how does this work? Well, the viral rods bond with the battery's electrodes effectively expanding their surface area. More surface area means the battery can hold more of a charge.

World's Highest Resolution Image


At a whopping 80-gigapixels, photographer Jeffrey Martin has officially captured the world's highest resolution image. It took three days to capture this image from atop the Center Point Building and required digitally stitching 7886 independant images into one masterwork via a Fujitsu CELSIUS computer.

The resolution of this 360 degree photograph is so high one could literally zoom in to see the time displayed on Westminster clock (well over a mile from the location this photo was taken) -or- clearly make out people and places located great distances from the image's point of origin

If printed, the image would span 115 feet (35.052 meters) long and 56 feet (17.0688 meters) high!\





Trees may replace street lights

Scientists in Taiwan may have just uncovered one of the most beautiful methods of energy conservation ever conceived.

This brilliant concept was envisioned by Dr. Yen-Hsun Wu who sought to find a method of creating light via a non-toxic means (unlike the highly efficient, but toxic phosphor powder used in LED lighting). The end result, trees, infused with gold nanoparticles that could replace traditional street lights. To test concept plausibility, gold nanoparticles were implanted in Bacopa caroliniana plants. After exposure to ultraviolet light (which is also emitted by our sun) the particles reacted with the naturally present chlorophyll and induced a red luminescence in the leaves. The vision is that some day street lights around the world could be replaced by such an aesthetically pleasing source of light that is both self perpetuating and a natural contributor to the ellimination of co2 emissions.
