The next big renewable energy source could be at our feet

Associate Professor Xudong Wang holds a prototype of the researchers’ energy harvesting technology, which uses wood pulp and harnesses nanofibers. The technology could be incorporated into flooring and convert footsteps on the flooring into usable electricity

Flooring can be made from any number of sustainable materials, making it, generally, an eco-friendly feature in homes and businesses alike. Now, however, flooring could be even more “green,” thanks to an inexpensive, simple method developed by University of Wisconsin–Madison materials engineers
