Turning Footsteps into Energy
The article “Kinetic Floor Tiles Harvest Energy from Footsteps” by Dezeen explores renewable energy that uses the act of walking to make it. The technology, developed by Pavegen and founded by Laurence Kemball-Cook, uses specially designed floor tiles to capture the mechanical energy created when people step on them and convert it into electricity.
"78% of the world’s energy is consumed in high-density urban areas, which is also where 60% of global greenhouse gases are produced."
"Millions of people moving around in urban areas generating energy as they go, and one inventor decided to come up with a way to capitalize on this abundance of motion. Laurence Kemball-Cook founded his company Pavegen in 2009 after conceptualizing the kinetic paving technology."
This idea is especially interesting for cities because urban areas have large populations and high amounts of foot traffic, but they often have limited physical space for traditional renewable energy systems such as solar panels and or wind turbines. I think that this concept is very interesting because it is solving the problem of limited space, kinetic flooring can be installed directly into places where people are already walking, including shopping centers, transportation stations, universities, stadiums, and even parks were people run, take their dogs, exercises, etc.
"Kinetic paving operates on the scientific principle of electromagnetic induction, which converts the mechanical energy of a footstep into electrical energy. It’s this property that led to the development of surface tiles that draw energy from people stepping on them—a totally free and clean source"
When someone steps on one of the tiles, the surface moves down slightly, compressing by approximately 10 millimeters. This movement activates an electromagnetic generator underneath the tile, converting the mechanical energy from the person's footsteps into electrical energy.
"Each step could create between 3 and 5 watt-seconds of energy when pressure is applied to an electromagnetic generator installed under the surface of the tile. This can either be stored in batteries for later use or instantly released to power lighting or low-energy devices like sensors, LED lights, charging stations, and signage."
While this is a relatively small amount from a single step, thousands of people walking across the tiles can create a larger amount of usable energy. The electricity can either be stored in batteries for later or low-energy devices such as LED lights, sensors, signs, and charging stations. Knowing this it makes an interesting thought of how we could use these types of tile sensors to activate something within the park. using this motion activated flooring we could create maybe a light source that walks with the user in certain sections of the trail that are difficult to see. or when someone is going up to use a restroom or facility. This concept makes me think back to a conversation that i had with Summer who is a naturalist at Deer Creek. She talked about how it hard for people to stop doing things they are accustomed to. So, if something was made that doesn't affect the user, they don't notice it while creating change; this technology combines sustainability with everyday human activity. People do not have to change their normal behavior. This technology turns existing human movement and public infrastructure into part of the energy system. As the technology continues to develop, it could become another tool for creating more sustainable and interactive cities.
