I have just been looking into how to power your laptop using solar energy. There are several ways you can do it depending on your situation and how you are traveling. Up until recently solar panels used to be quite bulky and heavy to carry around. But with the latest developments in Thin Film Technology , you now have flexible lightweight solar panels that you can roll up and carry around. I posted a page with different ideas on how to use a solar charger to power your laptop and cash in on the solar energy provided by the sun. Solar Energy is clean, green infinitely renewable and environmentally friendly.
