Here is another potential solution for people running low on energy whenever they are on the go. Thanks to the ingenious mind of a designer named Benjamin Beck of Berlin, the Scaraby Energy Backpack should be a handy item to have along especially if you have lots of gadgets in tow.
The backpack gets its power from the sun (solar power), possibly a great solution to have along during camping trips or when you are constantly traveling and/or exploring. It can be charged by movements as well, converting kinetic energy into useful electricity.
What they failed to mention was the battery life and how long it would take to charge the Scaraby Energy Backpack. Well, since this is a concept, those lacking information may very well come out if ever it does make the grade.
