Instead of thinking big - as in huge solar panels or enormous wind turbines - one designer started small, and worked his way up.Product designer Agustin Otegui came up with a unique solution to supplying large structures with alternative energy. His invention is called Nano Vent Skin, and it is just that: miniature wind turbines that form a "skin" that can wrap around buildings, tunnels, or anywhere else that needs energy.
Thousands of mini turbines would form the mesh skin (see photo at right for a magnified example of the turbines, which would measure about 25 millimeters long by 10 millimeters wide) and the energy they collected would be stored in storage units located around the structure. And as an added benefit, the wind turbines would also collect CO2.
Otegui says these types of nano-manufacturing are still years away, but he continues to think of other ways that his nano skin could be used.
