Until they make the solar panel removable, this is just an excuse to parade models around in underwear. Not that there’s anything wrong with that — parading around in underwear is a lot of fun.

A model (C) displays lingerie maker Triumph International Japan’s “Photovoltaic-Powered Bra” during an unveiling in Tokyo May 14, 2008. The camisole bra, which the company calls it as “earth and human friendly”, features a solar panel which can display messages on the removable small electric board when the cell generates electricity. The bra is also equipped with pads designed to hold beverages so that the usage of cans and plastic bottles can be reduced, the company said.

The bra can also power a mobile device, says Reuters.
