With cheap materials and simple technology, this method promises a new breakthrough in the green energy sector of the future.
Until now, thousands of engineers and scientists around the world have continued to research to improve the methods of solar energy exploitation even more effectively. Recently, at the laboratory of the University of Wisconsin-Madison, a scientist has invented a way to create new very unique electricity .
This high-tech material is completely familiar to us, it is wood pulp . Scientists have turned the waste wood pulp from the cutting of wood planks into cellulose nanofibers , then squeezed into wood-lined planks capable of generating electricity when we step up.
After treating wood pulp chemistry, the team led by science and technology professor Xudong Wang realized that this wood floor is capable of generating electricity because of the force that causes cellulose nanoparticles to friction. into each other. The amount of electricity emitted may even be enough to supply phone batteries and electric lights in the house.

Professor Wang's method is special in that it creates a new direction in the field of finding alternative energy sources . This finding has very cheap costs as well as very simple manufacturing techniques. If we could improve the technology further, this would be a potential method of providing alternative energy sources, perhaps even surpassing solar power.
"Unlike solar power , the electricity obtained from wooden slabs is much more stable . We can always get electricity regardless of how the weather changes. However, this method needs to be applied in places where people live and operate, " said Professor Wang.
Therefore, these wooden slabs when installed in densely populated areas such as sports stadiums or universities will help create a large amount of energy. In addition, these wooden slabs can be stacked on top of each other to help increase power output.
"Our initial test in the laboratory showed that these panels could go through millions of power generation cycles without any problems , " Wang added.Cellulose is simply a combination of Glucose molecules that are joined together to form a long chain. When we shrink this cellulose chain at the nanoscale, then reconstruct it into a long or chain-shaped polymer chain to form a lattice, we get Nanocellulose - a super-durable, ultra-light material. conductive. It is these properties that create a metamaterial with great potentials that can change our world.
