Technology of The City 2.0: Power by footsteps
In his talk at TEDxBerlin, industrial design engineer Laurence Kemball-Cook discussed his invention, the Pavegen, a paving tile made of recycled car tires that converts the kinetic energy of footsteps into electrical power:

I’m fascinated by the built environment—and how to make our cities more sustainable...I used to work for one of Europe’s largest energy companies, and I was looking at how to create a new form of power in our cities that was a renewable source of energy…so I thought, what about a power source that was literally under our feet? That every step people make—if we could capture that? And I thought, think of all the millions of people in the world; think of all the hundreds of cities; and think about what could be created by it.

So I created…a flexible paving slab that converts the kinetic energy of your footstep into electrical power…it stores the energy from many people walking—throughout the day, throughout the night—in our cities.

A set of Pavegen is currently installed in a school in the UK, where the foot traffic of the 1,100 students is used to power school lighting systems. Tiles were also installed in the West Ham tube station during the London Olympics. According to an article on Efergy about the installation, “[during] the 2 weeks of the games the 12 tiles produced 72m joules of energy or 20 kilowatt-hours..sufficient to keep the walkway streetlamps illuminated at full power through the night, and at half power during the day, with plenty of back-up energy left over to spare.”

TEDxTalks playlist: 5 talks on envisioning the city of the future—the City 2.0

What will the city of the future look like? According to the United Nations, by the year of 2050, 70% of the world’s population will be living in urban areas. Questions dominate our conception of the “City 2.0”: How will we transport ourselves? Where will we grow our food? How will we power our homes, our offices, our cities? What will happen to the natural world?

On October 13, 2012, communities across the globe will be asking these questions as part of TEDxCity2.0 day, a day during which nearly 70 TEDx events will be held in conjunction to dream the city of the future.

To celebrate the City 2.0 and the spirit of urban inspiration, here are 5 great TEDxTalks on the future of cities across the globe.
