Here’s something a bit out there that I picked up on inhabitat design:
There was an international competition for the reinvention, reinterpretation and revitalization of the Silk Road, the legendary trade route connecting Asia, Europe and Northern Africa that was for thousands of years the main thoroughfare for merchants, traders, and nomads.
A project by an architectural firm proposing a 15,000 km long CITY which will stretch from Venice to Xian, Shanghai to Tokyo, promoting trade via a new railways system functioning on gravitational platforms.
In addition to the air purifying skin, an innovative system of piezoelectric panels will be integrated into the tracks of the rail system, capturing energy created by the movement of the trains and converting it into electricity.
