Following on the heels of the Chopstick Bra and the No! Shopping Bag Bra, comes the Solar Power Bra to, you know, help your boobs generate some juice.

A waist-mounted solar panel powers a small, chest-mounted electronic billboard or any other electronic device you choose to connect.

There's also a reusable cup nestled--where else--in the bra's own cup. The whole thing aims to "stimulate" eco-awareness and give the Internet yet another glimpse at Japanese women in strange underwear.
