There are many forms of renewable energy being proposed, especially now that prices of gas and oil-based energy sources have gone through the roof. How about a bouncy bra iPod charger?
Boffins are planning to harness the energy of London commuters by using the energy generated by the city workers as they pound across railway stations, so the possibilities are endless.
Adrienne So, writing in Slate, has gone even further. She wants to power her iPod with her bouncing bosoms.
"As a woman who loves sports, I've always found the concept of breasts bothersome. They alternate between getting in my way and embarrassing me.
"Then one day recently I had an idea. As I rode public transportation to the office, my messenger bag slung uncomfortably across my chest, I thought, 'Why not put the girls to work?' The time seemed perfect for a bra that could harness the untapped power of breast motion."
If you're as interested in the physics of breast motion as I am, then her article is mind boggling.
She asked LaJean Lawson, a former professor of exercise science at Oregon State University who now works as a consultant for Nike to develop better sports bra designs, if breast power could be realised.
"It's just a matter of finding the sweet spot," she replied.
