It's not all about rubbish and recycling, saving the world can result in some fantastic new developments in the gadget world. One of the swankiest in recent times is the revolutionary Philips LCD eco TV.

The overall winner of the Consumer Electronics Show, this 42 inch flat screen is not only a great TV but also saves rain forests. It runs off a little as 75 watts, incorporating lead-free parts and only trace elements of mercury. Even the box and manual are made from recycled materials.
