People move. All the time. Wouldn’t it be great to harness that movement and help power our cities with the movement of people living in them?
In the future, pedestrians may generate energy for a city just by walking. A 2008 post from inhabitat.com talks about the application of a new technology (Piezoelectric flooring) to generate electricity by walking in a Tokyo train station: When the East Japan Railway Company (JR East) decided to invest in alternative energy sources, it only had to look to its users for the perfect source of energy.
Yesterday, we took a look at how piezoelectrics— crystals or ceramics that generate voltage when mechanical stress is applied— could allow cell phones to be powered by sound waves. Now the East Japan Railway Company (JR East) has announced that it is installing piezoelectric elements in the floors of its Tokyo station in an attempt to generate power from passengers passing through ticket gates. JR East will begin its experiment on December 10 and continue it until February 2009. The power-generating floor will cover an area of 25m squared and will be installed at 7 ticket gates and 7 staircase steps inside the gate. The company expects the floors to produce 1,400 kW/sec each day. If the piezoelectric experiment is successful, the train station floors will ultimately be used to power ticket gates and electronic display systems.
Piezoelectrics: A New Way to Produce Electricity - Texas Ever since electricity was harnessed and understood by humans, we have found new ways to generate it and put it to use. There was the Baghdad Battery, then lightning rods, and now there is the advanced science of piezoelectrics. Energy, of course, cannot be created or destroyed, but can be transferred from one kind to another. Piezoelectrics allow mechanical energy to become electricity, unlocking new possibilities for personal power sources.
i 1 Vote Interesting press release from Mike Gatto: After two years of work, Assemblyman Mike Gatto (D-Los Angeles) has found a new partner in the fight for green transportation and domestically produced alternative energy. Building on an idea of Gatto’s, the California Energy Commission (CEC) has announced that it will fund preliminary research on the potential of using California’s roadways to generate green electricity. The research will focus on the large-scale energy-harvesting capabilities of piezoelectric materials, which are currently used in everything from lighters to smart phones.
Abstract: The present invention relates to an apparatus system and method for power harvesting on roads and highways using a piezoelectric generator. The invention is to provide a system and a method for power harvesting comprising a plurality of piezoelectric devices embedded in a road and configured to produce electrical power when a vehicle traverses their locations.

A bill by Assemblyman Mike Gatto (D-Silver Lake) would take the power of the road for renewable energy.

Assemblyman Mike Gatto has introduced AB 306, the Roadway / Highway Electrification Act pilot. As of press time, the Sierra Club has taken no official position on it, but may be reviewing it in the coming months. The new bill proposes California invest in 'piezoelectric generation,' to capture the energy lost as traditional automobiles move along a stretch of pavement and place that power into the electrical grid.
Piezoelectric technology generates energy from pressure and stress on certain surfaces, and we’ve seen it harvest electricity from roads and dance floors to power lights and signs.
Piezoelectric Energy-Generating Roads Proposed for California Gatto – Inhabitat - Sustainable Design Innovation, Eco Architecture, Green BuildingWe are big fans of piezoelectricity here at Inhabitat — it essentially transforms kinetic energy into electrical current, and it can be implemented in a wide number of systems ranging from energy-generating railways to electronic circuits that recycle wasted heat .
Although the basic idea of attaching a generator to exercise equipment is many decades old, the press started lavishing attention on this concept four years ago, after a Hong Kong gym called California Fitness rigged 18 exercise machines to charge a battery and power fluorescent lights.

An Intriguing Possibility: The eco-efficient technology of piezoelectricity is essentially the concept of capturing the energy of exerted pressure.
An increasing number of consumer and industrial products that are untethered or need to become disconnected from the electrical outlet will become powered by some form of energy harvesting (EH) technology in the near future. The environmental and economic costs of changing and maintaining batteries for portable devices will motivate consumers and industrial end-users to investigate alternatives involving more autonomous power sources for a variety of device categories. Embedded systems are seen in every part of our daily lives. From the moment we get up in the morning, a programmable microchip in an alarm clock is responsible for keeping us on time.
