LED Blog: LED Lighting And All Things Green

Powered by rice....kinda.

Imagine a world where you could have a coat or a bag that has solar panels on it that would charge your gadgets while you were using it. What, that’s already been done? Well, sure but what I meant was have it done it a way that doesn’t scream “uber-nerd”. I mean how do we expect Lindsey Lohan to wear something that’s ugly?

Well, this technology may be it. It’s a solar cell that is created using tiny solar cells(1/4 the size of a grain of rice) that can potentially be put into a solution and sprayed on various material like a car, a house, your head, etc. and produces a seemingly unheard of amount of energy for the size/power ratio. Not only that, but they plan to double the power in just a few months. So potentially you could just walk around with one of these LED PAR30 bulbs in your backpack to bring light everywhere you go. I can’t wait for my hawaiian-shirt-powered laptop in the next few years.

Those crazy Chinese are at it again with another version of the Great Wall, at least from my perspective. I guess they’re in it to win it when it comes to grand displays to impress the rest of the world. Maybe this time they’re actually getting it right. This version is made up of LED lights and dwarves anything I’ve seen lately. Probably not the biggest I’ve EVER seen, but then again, it also isn’t an installation that uses half a million watts just for the sound system. No, this wall is so “great” because it is billed as a zero-energy fixture.

The LED wall contains solar panels that harvest the sun’s rays during the day, and uses that energy to display a video light show at night. How completely perfect. It’s like the true circle of life. In theory, you could build one of these in the middle of the desert, away from any and all civilization, and play large-than-life size movies off of it. Take that another step further and I would LOVE to play some old school Street Fighter II on a deserted island. Although GTA IV would definitely keep my attention for a little longer.

This is a one-off structure, so I don’t think they’re selling to the general public, but if you have to ask how much it would cost, you definitely can’t afford it. The new green buzzword of 2008 is “zero energy“. I’m already an adopter. I’ve had this solar-powered flashlight for years….
