Scientists figured out how to make transparent displays a while back, but that's not going to be much use in a portable device unless you can figure out a way to make the battery transparent as well. Now it looks like researchers have just about figured out how to do it, meaning we could have some totally see through gadgets before too long.
Developed by researchers at Stanford University, the batteries use lithium-ion technology just like most regular batteries, but they have managed to make the internal wiring so thin that it becomes invisible to the naked eye.
One member of the team, Yi Cui, has his own reasons for developing the battery. "I want to talk to Steve Jobs about this. I want a transparent iPhone!"
Sounds pretty cool to me.
