Months ago, our community decided on a crazy goal – the largest mobilisation on climate change in history. Just last Sunday, we blew past our wildest expectations, with a climate march *6 times* the size of anything before it!!! This was 80 city blocks of New York:
And this was London, Berlin, Bogota, Paris, Delhi, and Melbourne…
Over 675,000 of us marched around the world. It was a beautiful expression of our love for all that climate change threatens, and our hope that we can save this world and build a society powered by 100% safe, clean energy. Click to see more pictures from the day:
Together, we made history, but it’s just the beginning. The crucial Paris climate summit is 15 months from now — that’s where we need a global deal. By March next year, countries have pledged to make their national commitments — so our movement will divide to focus on these national targets. But every few months until Paris we’ll come together globally again and again, bigger and bigger, to beat a drum for change, for 100% clean energy, that our leaders can only follow. The movement we’ve been waiting for has begun.
Each day for the last six months, approximately 5,000 people passed through the turnstiles of the Saint-Omer subway station in northern France. Chances are good that the vast majority of them were so focused on the minutiae of their daily lives—Respond to the boss’ email now from my smartphone or from my computer when I get to the office? Un café express or un noir at the corner coffee cart?—that they didn’t realize that by putting one foot in front of the other they were serving the greater good by producing clean, renewable energy.
In March, 14 flooring tiles from London-based clean-tech company Pavegen Systems were installed at the mass-transit depot. The tiles, each roughly 7 by 24 inches, generate renewable electricity from the otherwise wasted energy of footsteps.
When a walker’s foot makes contact with the tile, it bends inappreciably, depressing an average of five millimeters each step and creating approximately seven watts of converted kinetic energy in the process. The slabs, made from 100 percent recycled rubber, can store energy for up to 72 hours via small built-in batteries.
The energy captured by the tiles at the Saint-Omer station has been used to power an LED bench lighting system and two USB ports installed in nearby benches, allowing commuters to charge their electronic devices as they wait for trains.
The concept was conceived in 2009 by Laurence Kemball-Cook, then a graduate student in industrial design at Loughborough University in the United Kingdom.
“I realized that although wind and solar alternatives were progressing exponentially, they were inefficient in urban environments due to high-rise infrastructure and pollution,” he says. “Given that 60 percent of the world’s population would be residing in urban environments by 2030, I decided to investigate further. I discovered footfall as an untapped, renewable resource that is efficient, constant, and literally all around us, to be used when and where it is needed.”
Since the first Pavegen tiles were installed at a U.K. school in 2010, the concept has spread across the Atlantic to the U.S. In January, Pavegen installed eight tiles in a hallway outside the cafeteria at New York City’s Riverdale Country School, the first American venue to feature the kinetic units. The captured electricity has been used to power a phone-charging dock and LED information boards that explain the innovation and potential uses of the technology.
“We received a highly positive reaction from both teachers and students—the fact that we’re educating aspiring innovators on a people-powered alternative to fossil fuels, whilst maintaining the fun factor, is a huge result for us,” says Kemball-Cook.
