One of the renewable energies that we always have on hand is solar energy, and we all know that we don't use it enough. One of the reasons why we aren't using solar energy more is that it's usually impractical. Hopefully things will change in the future and we will fully exploit this unlimited source of power. This is one of the reasons why I thought that this concept was so great. You'd just be walking around and charging your gadgets at the same time!
The design is by Koreans Hyun-Joong Kim and Kwang-Seok Jeong. Naturally, the glasses themselves don't need any power! The Self-Energy Converting Sunglasses are quite simple. The lenses of the glasses themselves have solar cells, collecting energy and powering some of your devices. For now, this technology is just a concept because the designers have envisioned a sort of solar cell dye, made up out of tiny solar transistors, assembled with nano-technology. We think that it's possible that actual see-through solar panels would come before these nano-technological appendages. A form of glass with transistors sandwiched in-between. That already exists and it's called intelligent glass, which can become dark on a touch of a button. With the advances in technology, it's probable that we will see window glass that are solar panels at the same time.
Even though this won't exist for a while, it makes you think about using the sun's energy to power your gizmos. Backpacks and shoulder bags are the ideal medium for this, since they have a large surface on their lid, which could be easily converted for a solar charging panel. However, they'd have to be quite rugged because of the usual wear and tear associated with daily use. We've featured quite a few here at Unplggd. [via Yanko Design]
