Among the highlights of last month's trip to the World Future Energy Summit was a tour of Masdar City, Abu Dhabi's living laboratory in sustainable development and what is held out to be among the most sustainable cities ever built (at least in the modern sense). Masdar City has progressed significantly since my last tour a little over a year ago. Most interestingly, Siemens has chosen to locate their Middle East headquarters at Masdar City - validating both the city's ambition and representing a solid commitment to sustainable development for the company.

I hope the short video below gives you an idea of what it's like to walk around the city, and a little more information about what's going on:

In case you'd like to see more about the personal rapid transit program at Masdar City, I made the following video last year which gives you a nice taste:
