iPhone and iPod docks are everywhere these days. But most, even the expensive ones, are made in China from plastic and require electricity to work properly.

When the iBamboo speaker hit the market last year, it blew the minds of Apple lovers and eco-geeks alike: using a simple piece of bamboo (a rapidly-growing, sustainable resource), the iBamboo amplifies the sound produced by the built-in speaker of the iPhone 4/4S...no electricity required!

And now, it's getting even better.

Prompted by iBamboo owners who complained that they were afraid to travel with their speaker, lest they chip or break the bamboo in the process, the company has announced plans to market an "urban" version made from recycled plastic (above).

"A plastic iBamboo would serve a different niche," reports Anatoliy Omelchenko of Triangle Tree. "First of all it would be an active effort to remove plastic, which takes thousands of years to degrade, from our environment. Second, a plastic iBamboo would be more fitting for people that would like to enjoy their music in more extreme conditions, as a plastic version would be more durable, and less prone to damage or defect. It would still have the trademark electricity-free design, available in both clear transparent and solid color."
