Taking those electroluminescent wires to a whole new level, a company called LumiLor has created a brushable/sprayable paint that casts a uniform fluorescent glow whenever a current is applied. So it can be used to cover irregularly shaped objects with ease, and as Boing Boing points out, it has the potential to revolutionize Burning Man. More »

Our planet’s recent close call with one asteroid, and direct visit from another has definitely made it seem important to consider how to avoid the pesky things in the future. One solution is to direct the Sun’s power into pulverizing lasers, but another option just involves covering incoming rocks with spray paint. Simple as that. More »

Who would have thought that a humble coat of paint would be able to help lower the mercury readings by up to 40 degrees Fahrenheit (22 degrees Celsius) on a hot day? Well, that is exactly what this light-colored, heat-reflecting asphalt and paint combination does, helping reduce the temperature of a parking lot (or wherever it is painted) whenever the sun decides to show up for work with full of zest. Of course, more or less everyone knows that painting sidewalks, walls and roofs with white would help lower temperatures somewhat, but the Lawrence Berkeley National Laboratory in Northern California decided to go ahead with commercially available heat-reflecting coatings to prove a point.

Not only did it help lower the overall temperature by a whole lot, in the long run when used in neighborhoods, it might even lower residents’ electricity use for air conditioning while doing their bit in the fight against global warming. Haley Gilbert, a research assistant at the Berkeley Lab who studies heat in cities, cited that “across an entire city, small changes in air temperature could be a huge benefit as it can slow the formation of smog.” Hmmm, perhaps Beijing might want to investigate into the use of such heat-reflecting paints.

Concrete jungles need to be maintained every few years with a fresh coat of paint, otherwise the scene would look like something out of a zombie apocalypse. Well, science had always drawn inspiration from nature, and this time around, it is a pair of butterfly wings that proved to be the impetus for a new material that not only repels water, but gleams with brilliant color (hmmm, qualities of Edward the vampire, perhaps?) Similar to iridescent butterflies, this particular material relies on tiny structures on its surface in order to achieve both qualities. Such a material could eventually be advanced to a stage where it sees action in sensors that regulate the interior temperature of “smart buildings. ” Taking into account minuscule bumps on butterfly wings that cause any water that hits the wing to form beads and roll away, such a concept also means there is no chance of dirt sticking to the wings – and in this case, a building.

The ultimate goal? An entire city of energy-efficient buildings, which is something bustling metropolises need these days. Of course, this material could also be used on the outside of buildings in order to deliver colorful designs which are more durable compared to conventional paint, resisting dirt and mildew in the process.
