What have in common a briefcase, a bonsai and a fan?

A briefcase, a bonsai and a fan may not have anything to do, but now if you'll have much in common, since all of these take advantage of solar energy to become sources.

PowerSafer proposes a briefcase Solar ComputerBag that besides being a classic case to protect your laptop has 4 solar panels which can recharge a battery inside the case and this in turn gives us until 2 hours of extra energy. These panels are made of the case so that we can place them in the best position at the sun. You can also connect a camera, a mobile phone or any player. It costs about 300 euros.

This Bonsai tree, designed by French Vivian Muller, instead of leaves brings solar panels to recharge batteries can be smaller. The branches can be moved so as to find the ideal position towards the sun.

This curious fan is ideal for your cap, especially on a sunny day because while the fan quietly cools you recharge it with solar energy.
