A "Tree" That Recharges Gadgets With the Sun's Energy
The most recent introduction into the growing variety of sun-collecting gadgets is Greendix’s solar-powered "fruit tree" that acts as a portable charging station. Its leaf-shaped solar panels charge up “energy apples,” which glow from green to red to show when they are “ripe” – or charged – and ready to use. The apple-shaped batteries can be used to recharge cell phones or iPods without using electricity.
While the idea of “energy apples” might seem a little extravagant, we think it’s exciting that solar-energy companies are trying to appeal to a younger audience.
