It’s not a technological innovation that will have hugely useful implications (I don’t think, at least) but the idea of transparent batteries is pretty cool and will make future handheld devices look awesome. That means you can have completely transparent iPods and such (and whatever amazing technological devices are developed in the future, for that matter).
The battery will be more powerful and transparent, giving it all kinds of uses. These batteries actually exists so it shouldn’t be long before a device is released that is entirely clear and beautiful. It’s a simple technological advance but it should be interesting and amazing and yet another confirmation that science is capable of great things when given the chance to shine. You have to love that someone wanted to create this, too.
