Could looking through trees be the view to a greener future? Trees replacing the clear glass in your windows is not a work of science fiction. Its happening now.Forest Products Laboratory researcher Junyong Zhu together with colleagues from the University of Maryland and University of Colorado has developed a transparent wood material that may be the window of tomorrow. Researchers found that transparent wood has the potential to outperform glass currently used in construction in nearly every way.While glass is the most common material used in window construction, it comes with quite a few bad consequences. Heat easily transfers through glass and amounts to higher energy bills when it escapes during cold weather and pours in when its warm. Glass production used for construction also comes with a heavy carbon footprint. Manufacturing emissions alone are approximately 25,000 metric tons per year, without considering the heavy footprint of transporting the glass.The innovation was developed using wood from the balsa tree, which is native to South and Central America. The team treated balsa wood to an oxidizing bath, where the wood is kept in a bleach solution at room temperature to remove the light-absorbing substance from the structure. The wood is then penetrated （注入）with a synthetic polymer called polyvinyl alcohol （PVA）, creating a product that is virtually transparent. So the transparent wood is created, which is far more durable and lighter than glass.Switching to transparent wood could prove to be cost efficient as well. It is approximately five times more thermally efficient than glass, cutting energy costs. It is made from a sustainable, renewable resource with low carbon emissions.With all of these potential benefits for consumers, manufacturi
