Ladies, take your battle for the environment a little closer to your heart with a solar-powered bra that can generate enough electric energy to charge a mobile phone or an iPod.
Lingerie maker Triumph International Japan unveiled its environmentally friendly, and green coloured, Solar Power Bra in Tokyo.
The bra features a solar panel worn around the stomach which requires light to generate electricity.
The concept bra will not be in stores anytime soon, said Triumph spokeswoman Yoshiko Masuda, as "people usually can not go outside without wearing clothes over it."
But it does send the message of how lingerie could possibly save the planet, Masuda said.
The Solar Energy Bra follows the company's other green-themed undergarments that include a bra that turns into a reusable shopping bag and one made of metal chopsticks to promote the use of reusable chopsticks.
