Designboom recently came up with a challenge for designers, who were supposed to image the future of computing. The winner was the following concept, of a tablet that requires finger energy to get charged. This green slate received the Fujitsu Design Award 2011in the “A Life With Future Computing” competition.

This is the Ecopad, a slate that recharges through piezoelectrics, meaning that it will gather up energy generated through the movement of the human hands as they get in contact with the touchscreen. There’s a statistic from Ecowizer saying that on average people press touchscreens over 10,000 times a day and this can be turned into energy, using a piezoelectricity film placed on the screen.

Thanks to their innovative idea, the designers of the Ecopad concept tablet received a prize of $1416. Congrats to them!
