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 Ltd unveiled its environmentally friendly, and green colored, "Solar Power Bra" on Wednesday in Tokyo which features a solar panel worn around the stomach.

The panel requires light to generate electricity and 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, adding that the bra should not be washed or sunned on a rainy day to avoid damaging it.

Being eco-friendly is now fashionable in Japan, and 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 that featured metal chopsticks to promote the use of reusable chopsticks.

"It is very comfortable and I can really feel involved in eco-friendly efforts as well," model Yuko Ishida said.

想把環保做到更“貼心”的女士現在可以選擇一種“太陽能文胸”了！這種文胸產生的電量能夠給手機或iPod充電。

日本“黛安芬”內衣公司于本周三在東京公布了這款綠色的“太陽能環保文胸”，這款文胸的主要特點是其腹部區域安有一塊太陽能面板。

黛安芬公司的女發言人增田美子說，這塊芯板采光后才能發電，不過這款“概念內衣”近期不會上市，因為“人們不可能只穿著內衣出門”。

但它的確能讓人們認識到內衣也可以保護我們的地球。此外，這種內衣不能洗滌或在雨天晾曬以避免損壞。

目前環保在日本十分流行。這款“太陽能文胸”推出前，黛安芬公司還推出了其它“綠色”主題的文胸，如可變身購物袋的文胸，以及旨在鼓勵人們使用非一次性筷子的可插“金屬筷”文胸等。

模特石田勇子說：“這款內衣非常舒適，穿上它讓我感到自己也為環保盡了一份力。”
