Anatomy of a Smart City

Anatomy of a Smart City | Sustainable ⊜ Smart Path | Scoop.it

The 19th century was a century of empires, 20th century was a century of nation states and the 21st century will be a century of cities...

 

This outstanding infographic (courtesy of postscapes.com) begins with some information about our current state of urbanization.

 

Did you know that 1.3 million people are moving to cities each week?! It then explains the need for smart cities and delves into what is required to establish these intelligent connected environments, how the smart city may take various forms in the developing worlds and what specific technologies are necessary to achieve such grand goals in practice.

We have been grateful to the wide array of planners, architects, techies, entrepreneurs and students of the built environment who have joined us on this journey. And the ‘Smart City‘ has featured again and again, whether it be a futurologist’s insights into the bionic, nature-centric adaptable cities of the future, or an economist’s keen ideas on instilling happiness in the built environment.

Eli Levine's curator insight, December 18, 2014 10:45 AM

There is an evolution taking place where politics, policy, technology, the environment, and the economy all intersect. This movement towards technical, empirically driven local policy making could be our saving grace.This could be the future of government.

A stunning infographic which predicts how urban living will change in this century.  Our age is truly becoming "a century of smart cities."  Exciting times lie ahead.  Aloha, Russ.

Smaller, cheaper, faster: Does Moore’s law apply to solar cells? | Scientific American | Sustainable ⊜ Smart Path | Scoop.it

The sun strikes every square meter of our planet with more than 1,360 watts of power. Half of that energy is absorbed by the atmosphere or reflected back into space. 700 watts of power, on average, reaches Earth’s surface. Summed across the half of the Earth that the sun is shining on, that is 89 petawatts of power. By comparison, all of human civilization uses around 15 terrawatts of power, or one six-thousandth as much. In 14 and a half seconds, the sun provides as much energy to Earth as humanity uses in a day.
