If you're tired of the battery going dead in your mp3 player at the beach - then a new invention might be for you.
Scientists have invented a solar powered bikini - a high tech bathing suit that can charge an mp3 player or other small devices while you relax in the sun.
The bikini does not weigh anymore than a regular bathing suit even with 40 solar cells attached.
However, they are set to cost more than €1,000.
