When they're not busy carving handsets out of teak (or rockin' out with their pupils), the folks over at NTT DoCoMo apparently focus their efforts on saving the environment. Next year, the Japanese provider will begin outfitting its expansive cellphone tower network with ten "green transmission stations," to be powered by an artillery of biofuels, wind and solar energy. This kind of infrastructure would obviously bring a smile to the face of ol' Mama Nature, but it could also help mitigate the adverse effects of power outages and elfin insurgents. And for that, we should all be grateful.
