This was the 2nd place entry in a renewable energy design contest. Although it wouldn't produce all that much power it would look pretty cool if built.
The hybrid system proposed
(combining solar and wind power) allows for a continuous production of
Energy. The project is based on the idea of utilizing the space between
the pillars of the existing viaducts to house a system of wind-powered
turbines which will be integrated into the structure. This ensures
contained land use and therefore a reduced impact on both landscape and
environment in addition to re-designing the visual profile of the
The solar park proposed in the competition will stretch the
full length of the inner carriageway, with the outer carriageway
remaining reserved for the transit of vehicles.
