Our friend Ruben Miller sent us an email on an alternative energy concept him and his wife submitted to the Metropolis’ Next Generation 2007 competition and we think it’s pretty cool. While the idea of harnessing human energy has been around for awhile, this one actually seems feasible. From the article,
“Imagine a nightclub where dancers generate the venue’s electricity just from the impact of their steps. With Redmond’s innovative flooring system, this vision of a human-powered energy source may be close to a reality. The floor tiles, cast in durable concrete and recycled glass, are fitted with piezoelectric brass-reinforced ceramic plates covered in nickel electrodes. With the impact of each footstep, a metal pointer inside the tile compresses the ceramic plate, generating an electric impulse. The resulting voltage activates four LED lights, visible through the glass surface, allowing energy-generating participants to see the power of their steps.”
This type of technology is intended for high-traffic areas; sidewalks, playgrounds, school hallways, etc. Obviously, you could do away with the LED lights and incorporate the idea into flooring that makes the whole thing less obvious. We love the concept, however, and hope Elizabeth and Ruben keep pushing to make it a reality.
