The innovation uses wood from the balsa tree, which is native to South and Central America, and claims to be five times more thermally efficient than glass. The transparent wood was created by a team at the University of Maryland and University of Colorado, which set out to find a greener alternative to conventional glass — a production that creates 25,000 tons of emissions each year. Along with contributing to greenhouse gases, glass contributes to a loss of energy. “Residential building windows in particular account for 10%—25% of the heat loss due to their poor thermal management capability,” the team wrote in the study. “Exploring energy efficient window materials is thus highly desirable to address heating costs, energy shortages, and the global impact of climate change associated with increased carbon emissions.” The team notes that the bonding between PVA and cellulose(纤维素) in the wood, creates a tightly packed structure that allows for more thermal protection and makes it more durable and lighter than glass. The team treated balsa wood in an oxidizing bath that bleached(漂白) it of nearly all visibility and then penetrated it with PVA — creating a product that was virtually transparent. Unlike traditional glass, the transparent wood can withstand much stronger impacts and will bend or splinter(裂成碎片) when damaged, instead of shattering(粉碎). “Switching to transparent wood could prove to be cost efficient as well,” researchers shared in a statement. “It is made from a sustainable, renewable resource with low carbon emissions. It can be produced with existing industrial processing equipment, making its manufacturing an easy prospect.” 1. What does the underlined word “thermally” in Paragraph 1 mean? A. Associated
