Oh, what wondrous things come from the land of Korea -- dancing emotional robot humanoids, oxygen-emitting robot plants, and multiple 24-hour StarCraft channels. It's all good, and we dig robotics and televised gaming, but this latest invention could be our favorite if it pans out. Professor Cho Jae-Phil and his team at Hanyang University have replaced the graphite in lithium batteries with a certain kind of silicon, which we're told can store eight times the power. No word on what the batteries have actually been used for yet, but it stands to reason they could eventually make it to consumer electronics. Now you see why we're willing to say this might be better than 24-hour StarCraft. Say it with us: 48-hour StarCraft.
