If you’ve been trying to latch onto the �green� movement, and haven’t had much success, why not start with something simple, like switching to solar power for charging your phone? Normally, the problem would be acquiring a clunky case that needed to sit out in the sun for several hours, which would also make it hot to the touch, but there are better methods now.

The XDModo Solar Charger sticks to your window, and catches the suns rays, which can be used to charge your smartphone. This way, it can take all the heat and energy, and just give you the latter while your phone stays cool, away from the window. It has a regular and micro USB output, and stores its power in an 1400mAh rechargeable lithium battery. This will give you about one good charge by today’s battery standards for smartphones. It will cost you around $66, which might seem a little excessive, but at least you’re doing your part to help the environment (and shaving a few pennies off your electric bill).
