Although the Sony Eclipse is only a concept at the moment, I wouldn't be surprised if it were to become a reality within the next few years.
The design was created by Hoang Nguyen and is supposed to use solar-power to sustain its functions. During the day, the gaming system will collect all the light energy it can get, so once the gamer decides to play, there will be enough energy that can last through the night.
Implications - The Sony Eclipse by Hoang Nguyen is currently only at the conceptual phase of its development, but boy, what a concept it is. Solar power is being used more and more in unconventional ways, and its impact will continue to spread amongst middle class-buyers.
