Greentastic Tablets

It is no lie that everything is going green -- from electronic cars to the clothes on your back -- and now LG has hopped on the bandwagon with its first solar-powered e-book. This is especially handy for those summer days lounging in the park; no one particularly likes getting halfway through a book for the device to die.

Able to last for four to five hours, the solar-powered e-book allows you to forget about the charger and just enjoy the summer day.
