How do you make a renewable, natural, oxygen-producing, CO2-storing material even more sustainable? Make it as close to zero-waste as possible. Wood waste left over after milling lumber already gets put to myriad valuable uses, from paper products to biomass fuel, and a new innovation will actually enable it to produce clean energy. Engineers at the University of Wisconsin-Madison have discovered a way to manufacture wood floors embedded with wood pulp nanofibers that generate electricity when you step on them.
Chemically treated, tiny cellulose fibers within the waste pulp produce an electrical charge when they come in contact with untreated nano fibers. Stepping on wood floors enhanced with these fibers generates electricity, effectively harnessing energy from footsteps without the need for complex equipment.
Published in the journal Nano Energy on September 24th, 2016, the method is ingeniously simple and inexpensive, with the potential to produce electricity that can be harnessed to power lights or charge batteries. The technology can easily be incorporated into virtually every … more/ Generating Renewable Energy
