Not quite an iPhone Nano, but a patent for a phone having
a bamboo casing with an “outer surface and a coating containing nanoparticles”. Bamboo has been chosen as it is “natural and recyclable”. The bamboo would be pre-treated with gamma-rays making it more durable and removing any bacteria, moisture, debris and contamination. To make the phone even more high tech the bamboo would be coated with nanoparticles such as titanium dioxide, silver or zinc dioxide.
Very environmentally friendly, but we were disappointed by the lack of a wind turbine.
