(Disclaimer: I stole the title of this post from the original article. Hey, if imitation is a sincere form of flattery...) Anyway, the Italian town of Torraca (population 1,200) is the first place on Earth to be entirely illuminated with light-emitting diodes (LEDs) instead of incandescent lighting. Lots of other cities around the world are following suit.

Though they're more expensive to buy up front, LEDs are much more energy efficient than old-school light bulbs, and they last a LOT longer.

"Potential energy savings, however, appear to hold more sway with cities and building owners than cost. After all, some 22 percent of all electricity use in the U.S. is devoted to lighting, according to the U.S. Department of Energy—and switching to LEDs could save $280 billion by 2028. In fact, researchers at the Rensselaer Polytechnic Institute in Troy, N.Y., estimate that replacing incandescents with LEDs could save $1.83 trillion in energy costs globally over the next decade and eliminate the need for 280 1,000-megawatt power plants."

Check it out y’all: this could be the next Playstation Portable!

That model isn’t exactly in production yet, though—it’s a conceptual design of what the next PSP system could be, based on existing technology (or technology that will be practical within a few years). Its designer, Tai Chiem, is exploring how the technology could be implemented in multiple portable electronic devices, including gaming systems.

For those of you unable or unwilling to click on the link above, the new PSP concept is based on a large, flexible screen that can roll up around the cylindrical controller (which looks to be about the same size and shape as a cigar case). Controls would be on the face of the cylinder, and stereo speakers would occupy each end. The screen, when unrolled, would be made stiff by a small electrical charge.

The screen is based on organic light emitting diode technology. The difference from normal LED tech is that the light emitting layers of OLEDs are based on organic compounds. A variety of compounds, which emit different colored light when subjected to electrical current, are deposited on a polymer surface in a similar way to ink being deposited on paper during the printing process. Although there is some concern over the degradation of the light emitting compounds over time, because OLEDs emit light themselves, they don’t need a backlight like LCD screens, and they require less power to run. OLED screens are already being manufactured by Sony, and have been used in demonstrations of flexible display screens.

Because the controls of this future PSP don’t exactly look comfortable to handle, I’m assuming that the impetus of the design was primarily ease of smuggling. You wouldn’t want to try to sneak a whole crate of these anywhere, but just one of them, I’m guessing, would fit pretty well in any one of a number of common smuggling compartments. The location of the speakers on each end could lend itself to some hilarious sound effects too. The potential for a stray electric charge to erect the screen, however, is disturbing. It could make things tremendously uncomfortable for the smuggler, and put an end to any sneakiness previously underway.

What do y’all think? Cool technology for portable gaming? Or is this going in the wrong direction?
