The scenery of the passengers waiting for flights have changed dramatically in the recent years. While newspapers and magazines were the dominant choices in the past, the trend has shifted to smartphones and/or tablet PCs. Although these new gadgets provide limitless choice of killer-applications, spending too much time on it can kill the battery and it can do it fast.

CNet introduced Jung Inyoung’s concept bag that provides power using kinetic energy. (http://www.cnet.com.au/suitcase-powers-your-devices-339330076.htm)

The two gears on the bag’s wheels collect energy as you stroll around the airport. It stores energy in a charge battery and delivers it through the port located on the top of the bag. There’s also an LED battery indicator that displays how much energy is stored in the battery.

There are, however, electrical outlets on the walls of the airport but even these are very much competitive.

Jung’s newly designed bag can get useful for frequent and busy travellers however the concept bag is not yet for sale.
